Assignment Operators

Along with the equal operator, there is one assignment operator that corresponds to each arithmetic and concatenation operator. Its symbol is obtained by appending an equal sign to the arithmetic or concatenation symbol.

The arithmetic and concatenation operators work as follows. They all take the form:

where <operator> is one of the arithmetic or concatenation operators. This is equivalent to:

To illustrate, consider the addition assignment operator. The expression:

is equivalent to:

which simply adds 1 to x. Similarly, the expression:

which concatenates the string "end" to the end of the string s.

All of the “shortcut” assignment operators—such as the addition assignment operator or the concatenation assignment operator—are new to VB .NET.

The assignment operators are:

The equal operator, which is both an assignment operator and a comparison operator. For example:

Note that in VB .NET, the equal operator alone is used to assign all data types; in previous versions of VB, the Set statement had to be used along with the equal operator to assign an object reference.

Addition assignment operator. For example:

adds 1 to the value of lNumber and assigns the result to lNumber.

Subtraction assignment operator. For example:

subtracts 1 from the value of lNumber and assigns the ...

Visual Basic Operators

In Visual Basic, Operator is a programming element that specifies what operation needs to perform on operands or variables . For example, an addition (+) operator in Visual Basic is used to perform the sum operation on operands.

Visual Basic Operator Types

In Visual Basic different types of operators are available; those are

  • Arithmetic Operators
  • Assignment Operators
  • Logical/Bitwise Operators
  • Comparison Operators
  • Concatenation Operators

Now, we will learn each operator in a detailed manner with examples in the Visual Basic programming language.

Visual Basic Arithmetic Operators

In Visual Basic, Arithmetic Operators are useful for performing basic arithmetic calculations like addition, subtraction, division, etc., based on our requirements.

The following table lists the different arithmetic operators available in Visual Basic.

Visual Basic Assignment Operators

In Visual Basic, Assignment Operators are useful to assign a new value to the operand.

The following table lists the different assignment operators available in Visual Basic.

Visual Basic Logical / Bitwise Operators

In Visual Basic, Logical / Bitwise Operators are useful to perform the logical operation between two operands like AND, OR, etc., based on our requirements. The Logical / Bitwise Operators will always work with Boolean expressions ( true or false ) and return Boolean values.

The following table lists the different types of logical/bitwise operators available in Visual Basic.

Visual Basic Comparison Operators

In Visual Basic, Comparison Operators are useful to determine whether the defined two operands are equal, greater than or less than, etc., based on our requirements.

Visual Basic operators

last modified October 18, 2023

In this part of the Visual Basic tutorial, we talk about operators.

An operator is a special symbol which indicates a certain process is carried out. Operators in programming languages are taken from mathematics. Programmers work with data. The operators are used to process data.

We have several types of operators:

Arithmetic operators

Boolean operators.

  • Relational operators

Bitwise operators

An operator may have one or two operands. An operand is one of the inputs (arguments) of an operator. Those operators that work with only one operand are called unary operators . Those who work with two operands are called binary operators .

The + and - signs can be addition and subtraction operators as well as unary sign operators. It depends on the situation.

The plus sign can be used to indicate that we have a positive number. But it is mostly not used. The minus sign changes the sign of a value.

Multiplication and addition operators are examples of binary operators. They are used with two operands.

The assignment operator

The assignment operator = assigns a value to a variable. A variable is a placeholder for a value. In mathematics, the = operator has a different meaning. In an equation, the = operator is an equality operator. The left side of the equation is equal to the right one.

Here we assign a number to the x variable.

The previous expression does not make sense in mathematics. But it is legal in programming. The expression adds 1 to the x variable. The right side is equal to 2 and 2 is assigned to x .

This code example results in syntax error. We cannot assign a value to a literal.

The following is a table of arithmetic operators in Visual Basic.

The following example shows arithmetic operations.

In the preceding example, we use addition, subtraction, multiplication and division operations. This is all familiar from the mathematics.

Next we show the distinction between normal and integer division.

In the preceding example, we divide two numbers using normal and integer division operator. Visual Basic has two distinct operators for division.

We use floating point data types.

This is floating-point division.

This is integer division. The result of this operation is always and integer.

The last two operators that we mention are modulo operator and exponentiation operator.

The Mod operator is called the modulo operator. It finds the remainder of division of one number by another. 9 Mod 4 , 9 modulo 4 is 1, because 4 goes into 9 twice with a remainder of 1. Modulo operator can be handy for example when we want to check for prime numbers.

Finally, we mention exponentiation operator.

9 ^ 2 = 9 * 9 = 81

Concatenating strings

In Visual Basic we have two operators for string concatenation. The plus + operator and the & ampersand operator. We can also use the String.Concat method.

We join three strings.

In Visual Basic, we have the following logical operators. Boolean operators are also called logical.

Boolean operators are used to work with truth values.

Many expressions result in a boolean value. Boolean values are used in conditional statements.

Relational operators always result in a Boolean value. These two lines print False and True.

The body of the If statement is executed only if the condition inside the parentheses is met. The x > y returns True, so the message "y is greater than x" is printed to the terminal.

Example shows the logical And operator. It evaluates to True only if both operands are True.

The logical Xor operator evaluates to True, if exactly one of the operands is True.

The logical Xor evaluates to False if both operands are True or both False.

The logical Or operator evaluates to True, if either of the operands is True.

If one of the sides of the operator is True, the outcome of the operation is True.

The negation operator Not makes True False and False True.

The example shows the negation operator in action.

AndAlso , OrElse operators are short circuit evaluated. Short circuit evaluation means that the second argument is only evaluated if the first argument does not suffice to determine the value of the expression: when the first argument of And evaluates to false, the overall value must be false; and when the first argument of Or evaluates to true, the overall value must be true. Short circuit evaluation is used mainly to improve performance.

An example may clarify this a bit more.

We have two functions in the example. Functions, unlike subroutines, return values. This is the main difference between them.

The one function returns False. The short circuit AndAlso does not evaluate the second function. It is not necessary. Once an operand is False, the result of the logical conclusion is always False. Only "Inside one" is printed to the console.

In the second case, we use the And . In this case, both functions are called. Even though it is not necessary for the result of the expression.

Relational Operators

Relational operators are used to compare values. These operators always result in a boolean value.

Relational operators are also called comparison operators.

As we already mentioned, the relational operators return boolean values. Note that in Visual Basic, the comparison operator is = .

Notice that the relational operators are not limited to numbers. We can use them for other objects as well. Although they might not always be meaningful.

We can compare string objects too. Comparison operators in a string context compare the sorting order of the characters.

What exactly happens here? Computers do not know characters or strings. For them, everything is just a number. Characters are special numbers stored in specific tables. Like ASCII.

Internally, the a and b characters are numbers. So when we compare two characters, we compare their stored numbers. The built-in Asc function returns the ASCII value of a single character.

In fact, we compare two numbers, 97 with 98.

Say we have a string with more characters. If the first characters are equal, we compare the next ones. In our case, the b character at the second position has a greater value than the a character. That is why "ab" string is greater than "aa" string. Comparing strings in such a way does not make much sense, of course. But it is technically possible.

Finally, we mention the Is operator. The operator checks if two object references refer to the same object. It does not perform value comparisons.

We create three objects and compare them with the Is operator.

We declare and initialise two Object instances. The Object class is a base class for all classes in the .NET framework. We describe it later in more detail.

The third variable is only declared.

The o3 now refers to the o2 object. They are two references to the same object.

In the first case, we get False. The o1 and o2 are two different objects. In the second case, we get True. The o3 and o2 refer to the same object.

Decimal numbers are natural to humans. Binary numbers are native to computers. Binary, octal, decimal, or hexadecimal symbols are only notations of the same number. Bitwise operators work with bits of a binary number. Bitwise operators are seldom used in higher level languages like Visual Basic.

The bitwise negation operator changes each 1 to 0 and 0 to 1.

The operator reverts all bits of a number 7. One of the bits also determines, whether the number is negative or not. If we negate all the bits one more time, we get number 7 again.

The bitwise and operator performs bit-by-bit comparison between two numbers. The result for a bit position is 1 only if both corresponding bits in the operands are 1.

The first number is a binary notation of 6, the second is 3 and the result is 2.

The bitwise or operator performs bit-by-bit comparison between two numbers. The result for a bit position is 1 if either of the corresponding bits in the operands is 1.

The result is 00110 or decimal 7.

The bitwise exclusive or operator performs bit-by-bit comparison between two numbers. The result for a bit position is 1 if one or the other (but not both) of the corresponding bits in the operands is 1.

The result is 00101 or decimal 5.

Compound assignment operators

The compound assignment operators consist of two operators. They are shorthand operators.

The += compound operator is one of these shorthand operators. They are less readable than the full expressions but experienced programmers often use them.

Other compound operators are:

Operator precedence

The operator precedence tells us which operators are evaluated first. The precedence level is necessary to avoid ambiguity in expressions.

What is the outcome of the following expression, 28 or 40?

Like in mathematics, the multiplication operator has a higher precedence than addition operator. So the outcome is 28.

To change the order of evaluation, we can use parentheses. Expressions inside parentheses are always evaluated first.

The following list shows common Visual Basic operators ordered by precedence (highest precedence first):

Operators on the same line in the list have the same precedence.

In this code example, we show some common expressions. The outcome of each expression is dependent on the precedence level.

This line prints 28. The multiplication operator has a higher precedence than addition. First the product of 5*5 is calculated. Then 3 is added.

In this case, the negation operator has a higher precedence. First, the first True value is negated to False, than the Or operator combines False and True, which gives True in the end.

Associativity

Sometimes the precedence is not satisfactory to determine the outcome of an expression. There is another rule called associativity . The associativity of operators determines the order of evaluation of operators with the same precedence level.

What is the outcome of this expression? 9 or 1? The multiplication, deletion and the modulo operator are left to right associated. So the expression is evaluated this way: (9 / 3) * 3 and the result is 9.

Arithmetic, boolean, relational and bitwise operators are all left o right associated.

On the other hand, the assignment operator is right associated.

If the association was left to right, the previous expression would not be possible.

The compound assignment operators are right to left associated.

You might expect the result to be 1. But the actual result is 0. Because of the associativity. The expression on the right is evaluated first and than the compound assignment operator is applied.

AddressOf operator

The AddressOf operator creates a function delegate that points to another function. Delegates are type safe function pointers, they are used to call methods of other objects.

In the code example, we use the AddressOf operator to point to two different subroutines.

We need to declare a delegate.

The delegate takes the address of a subroutine using the AddressOf operator. Now we have a type-safe pointer to the Message1 subroutine.

The Invoke method calls the method, to which the delegate points.

Now we give the delegate an address of another subroutine.

Both messages are printed to the console.

In this part of the Visual Basic tutorial, we covered the operators.

The Assignment Statement

Format: <variable name> = <expression>

The assignment statement causes the value of the expression on the right side of the equal sign to be stored in the variable specified on the left side of the equal sign.

An expression can be a constant, variable, or any valid combination of constants and/or variables connected with the operators such as +, -, *, and /.

The assignment statement has the form variable = constant

(i.e., the <expression> is a constant)

If the variable name on the left of the equal sign is a string variable, then the constant must be a string constant enclosed in quotes.  The quotes are not stored.  Examples follow:

Assume that the following variables are declared:

The statement

      strCustName = "BOB SMITH"

would cause the characters BOB SMITH to be stored in the variable strCustName.

      strCustAddr = "123 MAIN ST."

would cause the characters 123 MAIN ST. to be stored in the variable strCustAddr.

You can also declare and initialize a variable in one line:

I will recommend declaring and initializing the variables in different lines.

If the variable name on the left of the equal sign is a numeric variable (Integer, Long, Single, Double,Decimal), then the constant must be a valid numeric constant.  Numeric constants must not be enclosed in quotes.  They must consist only of the digits 0 through 9 and can optionally have a leading sign (- or +) and may have one decimal point.  Examples:

The following statements would cause the specified quantities to be stored in these variables:

Date and time values are stored internally in a special format, but you don’t need to know the exact format. They are double precision numbers: the integer part represents date and the fraction part represents the time.  Assume that the following variable is declared:

                Dim dtmHireDate As Date

The following statement would cause the internal representation of November 29, 1999 to be stored in the variable dtmHireDate:

            dtmHireDate = #11/29/99#

The statements given below are also the valid statements

            dtmHireDate = #11/29/99 6:30:11 PM#

            dtmHireDate =  “November 2, 1999”

            dtmHireDate =  Now( )

Note: Whenever we assign a value to a variable name, the previous value stored in that variable is destroyed and replaced with the new value.  This is called a "destructive replacement" or "destructive write".  For example, if the previous value of the variable intI was 2, and then the statement intI = 6 was executed, the new value of intI would be 6 (the 6 would replace the 2).

The assignment statement has the form variable = variable

(i.e., the <expression> is a variable)

The contents of the variable on the right of the equal sign will be copied to the variable on the left of the equal sign, replacing the previous contents of the variable on the left.  The contents of the variable on the right will remain unchanged.

The examples below assume that the following variables have been declared:

           

The assignment statement has the form variable = expression

(i.e., the <expression> is an arithmetic expression)

If an arithmetic expression is on the right of the equal sign, the expression is evaluated and the result of the expression is stored in the variable on the left of the equal sign.

For example, given the two statements:

In the second statement above, VB .NET will determine that the variable intI contains 2, add the constant 4 to it, and store the result (6) in intJ.

Given these two statements:

In mathematics, you could never have a statement like the second one above (intI = intI + 1), because in mathematics, the "="  indicates equality.  But in VB .NET, the "=" does not indicate equality; rather, it means "is replaced by" - i.e., the expression on the right (intI + 1) is first evaluated and determined to be the value 3.  The 3 is then stored in the variable on the left (which happens to be intI).

Other assignment statement notes:

No expression on left of equal sign

There can never be an expression on the left of the equal sign.  For example,

            A + B = C + D

is invalid, it means nothing in VB .NET.  By definition, the function of the assignment statement is to store a value in the variable specified on the left of the equal sign.

Assignment statements with mixed data types

In previous versions of BASIC and VB, you could only assign a string constant or another string variable to a string variable, and you could only assign a numeric constant, numeric variable, or numeric expression to a numeric variable.  Violation of this rule resulted in the generation of a Type Mismatch error.  In later versions of VB, this rule has been relaxed (only if Option Strict is OFF in VB .NET) – basically, VB will convert one data type to another if it possibly can; if it can't perform a suitable conversion, the "Type Mismatch " error will still occur.  Generally, "mixed-mode" assignment statements should be avoided when possible; they are inefficient and may sometimes produce unexpected results.

Regarding the last statement, if the decimal portion of a Single or Double is exactly .5, VB always rounds to the nearest even number when converting to an Integer or Long. This is sometimes referred to as "bank rounding".

In the "mixed mode" assignment statements shown above, VB would perform the necessary conversions in these cases wherever it could. Such conversions are called implicit conversions .

In VB, you can also use a set of functions that explicitly convert (or "cast") one type of data to another.  The set of functions that enable you to do this all begin with the letter "C": CBool, CByte, CChar, CDate, CDbl, CDec,  CInt, CLng, CSng, CStr, CObj, and CShort. There are also two older functions, Val and Str, which enable you to perform conversions as well. These functions will be covered in a later topic.

Assigning Data to Arrays

Given the following definitions:

Dim aintCount(9) As Integer

Dim asngSales(4,5) As Single

The following would be valid assignment statements:

      aintCount(4) = 36

      asngSales(2, 3) = 12543.22

You can also assign the arrays while declaring them:

Dim aintCount(3) As Integer = {0,1,2,3}

Assigning Data to Structures

      Public Structure EmployeeName

          FirstName As String

          MidInit As String

          LastName As String

      End Structure

      Public Structure EmployeeRecord

          udtEmpName As EmployeeName

          dtmHireDate As Date

          sngHourlyRate As Single

          dblQuarterlyEarnings(4) As Double

      Dim udtEmpRec As EmployeeRecord

      Dim audtEmpRec(10 As EmployeeRecord

      udtEmpRec.sngHourlyRate = 28.75

      audtEmpRec(3).dtmHireDate = #1/15/2001#

      udtEmpRec.udtEmpName.MidInit = "B"

      audtEmpRec(4).dblQuarterlyEarnings(3) = 14950.00

Using With/End With

You can use a With/End With block to "factor out" a qualifying reference in a group of statements. For example, the following sets of statements are equivalent:

With statement blocks can be nested. The following sets of statements are equivalent:

  • Press F5 to test the application
  • After using it, close the form
  • After using the form, close it

Operators and Expressions in Visual Basic

  • 13 contributors

An operator is a code element that performs an operation on one or more code elements that hold values. Value elements include variables, constants, literals, properties, returns from Function and Operator procedures, and expressions.

An expression is a series of value elements combined with operators, which yields a new value. The operators act on the value elements by performing calculations, comparisons, or other operations.

Types of Operators

Visual Basic provides the following types of operators:

Arithmetic Operators perform familiar calculations on numeric values, including shifting their bit patterns.

Comparison Operators compare two expressions and return a Boolean value representing the result of the comparison.

Concatenation Operators join multiple strings into a single string.

Logical and Bitwise Operators in Visual Basic combine Boolean or numeric values and return a result of the same data type as the values.

The value elements that are combined with an operator are called operands of that operator. Operators combined with value elements form expressions, except for the assignment operator, which forms a statement . For more information, see Statements .

Evaluation of Expressions

The end result of an expression represents a value, which is typically of a familiar data type such as Boolean , String , or a numeric type.

The following are examples of expressions.

' The preceding expression evaluates to 9.

15 * System.Math.Sqrt(9) + x

' The preceding expression evaluates to 45 plus the value of x.

"Concat" & "ena" & "tion"

' The preceding expression evaluates to "Concatenation".

763 < 23

' The preceding expression evaluates to False.

Several operators can perform actions in a single expression or statement, as the following example illustrates.

In the preceding example, Visual Basic performs the operations in the expression on the right side of the assignment operator ( = ), then assigns the resulting value to the variable x on the left. There is no practical limit to the number of operators that can be combined into an expression, but an understanding of Operator Precedence in Visual Basic is necessary to ensure that you get the results you expect.

Logical and Bitwise Operators

The logical and bitwise Operators work with Boolean (true or false) conditions, and if the conditions become true, it returns a Boolean value. The following are the logical and bitwise Operators used to perform the various logical operations such as And, Or, Not, etc. on the operands (variables). Suppose there are two operand A and B, where A is True, and B is False.

Example of Logical and Bitwise Operator:

Operator Precedence in VB.NET

Operator precedence is used to determine the order in which different Operators in a complex expression are evaluated. There are distinct levels of precedence, and an Operator may belong to one of the levels. The Operators at a higher level of precedence are evaluated first. Operators of similar precedents are evaluated at either the left-to-right or the right-to-left level.

The Following table shows the operations, Operators and their precedence -

  1. Assignment Operators

    Visual Basic guide Language reference Assignment Operators (Visual Basic) Article 09/15/2021 10 contributors Feedback The following are the assignment operators defined in Visual Basic. = Operator ^= Operator *= Operator /= Operator \= Operator += Operator -= Operator <<= Operator >>= Operator &= Operator See also

  2. = Operator

    Syntax VB variableorproperty = value Parts variableorproperty Any writable variable or any property. value Any literal, constant, or expression. Remarks The element on the left side of the equal sign ( =) can be a simple scalar variable, a property, or an element of an array. The variable or property cannot be ReadOnly.

  3. += Operator

    The += operator adds the value on its right to the variable or property on its left, and assigns the result to the variable or property on its left. The += operator can also be used to concatenate the String expression on its right to the String variable or property on its left, and assign the result to the variable or property on its left. Note

  4. &= Operator

    The &= operator concatenates the String expression on its right to the String variable or property on its left, and assigns the result to the variable or property on its left. Overloading The & Operator can be overloaded, which means that a class or structure can redefine its behavior when an operand has the type of that class or structure.

  5. .net

    2 Firstly, I am aware of the similar question here: Assignment "=" operator in VB.NET 1.1 Suppose I have a VB.NET structure which contains an ArrayList: Structure MarbleCollection Private marbles As ArrayList End Structure Class Marble Public name As String Public radius As Double End Class

  6. VB.Net

    There are following assignment operators supported by VB.Net − Example Try the following example to understand all the assignment operators available in VB.Net − Module assignment Sub Main() Dim a As Integer = 21 Dim pow As Integer = 2 Dim str1 As String = "Hello!

  7. Assignment Operators

    The assignment operators are: =. The equal operator, which is both an assignment operator and a comparison operator. For example: oVar1 = oVar2. Note that in VB .NET, the equal operator alone is used to assign all data types; in previous versions of VB, the Set statement had to be used along with the equal operator to assign an object reference.

  8. Visual Basic Operators

    Visual Basic Arithmetic Operators In Visual Basic, Arithmetic Operators are useful for performing basic arithmetic calculations like addition, subtraction, division, etc., based on our requirements. The following table lists the different arithmetic operators available in Visual Basic. Visual Basic Assignment Operators

  9. Operators in Visual Basic

    The assignment operator The assignment operator = assigns a value to a variable. A variable is a placeholder for a value. In mathematics, the = operator has a different meaning. In an equation, the = operator is an equality operator. The left side of the equation is equal to the right one. x = 1 Console.WriteLine (x) ' Prints 1

  10. The Assignment Statement

    An expression can be a constant, variable, or any valid combination of constants and/or variables connected with the operators such as +, -, *, and /. The assignment statement has the form. (i.e., the. If the variable name on the left of the equal sign is a string variable, then the constant must be a string constant enclosed in quotes.

  11. Microsoft Visual Basic

    Start Microsoft Visual Basic and, on the opening dialog box, double-click Standard EXE; To save the project, on the main menu, click File -> Save Project; Locate your MS Visual Basic folder created in the first lesson and display it in the Save In combo box; Click the Create New Folder button.

  12. VB.net Operators

    Assignment Operators in VB.net Description Example = It is a simple assignment Operator used to assign a right-side operand or value to a left side operand. X = 5, X assign a value 5 X = P + Q, (P + Q) variables or value assign to X. += An Add AND assignment Operator is used to add the value of the right operand to the left operand.

  13. *= Operator

    The *= operator first multiplies the value of the expression (on the right-hand side of the operator) by the value of the variable or property (on the left-hand side of the operator). The operator then assigns the result of that operation to the variable or property. Overloading

  14. Operators

    An operator is a symbol which has special meaning and performs an operation on single or multiple operands like addition, substraction etc. VB.net provides rich set of in-built operators. Types of Operators in VB.net 1. Arithmetic Operators. Arithmetic operators are used to perform arithmetic operations on operands.

  15. \= Operator

    The \= operator divides the value of a variable or property on its left by the value on its right, and assigns the integer result to the variable or property on its left For further information on integer division, see \ Operator (Visual Basic). Overloading

  16. Operators and Expressions

    An operator is a code element that performs an operation on one or more code elements that hold values. Value elements include variables, constants, literals, properties, returns from Function and Operator procedures, and expressions. An expression is a series of value elements combined with operators, which yields a new value.

  17. Why aren't assignment operators overloadable in VB.NET?

    Assignment operators cannot be overloaded, but +=, for example, is evaluated using +, which can be overloaded. These operators cannot be overloaded. struct MyType1 { ... public static explicit operator MyType1 (MyType2 src) //explicit conversion operator { return new MyType1 { guts = src.guts }; } } Ticket closed as "Won't Fix" in 2004 - rofl.

  18. Detecting or preventing assignment operator to a class

    Public Class AnyValue Private value As Int32 Public Sub New (ByVal aValue As Int32) value = aValue End Sub End Class 'I want to be able to do this: Dim val As New AnyValue (8) 'But not this. val = New AnyValue (9) Or it is possible to stop the assignment or detect when the operator = is used. It's an interesting question.
