What are VB.net Operators?
The VB.net Operator is a symbol that instructs the compiler to carry out particular logical or mathematical operations.
The Operator symbol is used in VB.net programming to execute various operations on variables.
There are many types of operators in VB.net that assist with applying logical and mathematical operations to data values.
In the VB.net programming language, the Operator precedence is used to specify the order in which several Operators are executed.
Operator is a specialized symbol in VB.net that instructs the compiler to apply a particular logical or mathematical operation to the data values.
An operand is the data value itself, which can be either a variable or a constant. The operator applies different operations on the operand.
How Many Types of Operators Used in VB.net?
The following are the types of operators that are used in VB.net extensive built-in operator library.
- Arithmetic Operators
- Comparison Operators
- Logical/Bitwise Operators
- Bit Shift Operators
- Assignment Operators
- Miscellaneous Operators
VB.net Arithmetic Operators
The Arithmetic Operators in VB.net, are used to perform mathematical operations such as subtraction, addition, multiplication, division, etc. on the operands in VB.net.
The following table shows all the arithmetic operators supported by VB.net.
| Arithmetic Operators in VB.net | Description | Example |
|---|---|---|
| ^ | It is an exponentiation Operator that is used to raises one operand to the power of another operand. | Y ^ X (X to the power Y) |
| + | The addition Operator is used to add numeric data, as well as concatenate two string variables. | X + Y |
| – | It is a subtraction Operator, which is used to subtract the second operand from the first operand. | X – Y |
| * | The multiplication Operator is used to multiply the operands | X * Y |
| / | It is a division Operator used to divide one operand by another operand and returns a floating-point result. | X / Y |
| \ | It is an integer division Operator, which is similar to division Operator, except that it returns an integer result while dividing one operand to another operand. | X \ Y |
| Mod | It is a modulo (Modulus) Operator, which is used to divide two operands and returns only a remainder. | X Mod Y |
Example Program of VB.net Arithmetic Operators:
Imports System
Module Arithmetic_Operator
Sub Main()
'Declare a, b And c as integer Data Type()
Dim a, b, c As Integer
Dim d As Single
a = 17
b = 4
' Use of + Operator
c = a + b
Console.WriteLine(" Sum of a + b is {0}", c)
'Use of - Operator
c = a - b
Console.WriteLine(" Subtraction of a - b is {0}", c)
'Use of * Operator
c = a * b
Console.WriteLine(" Multiplication of a * b is {0}", c)
'Use of / Operator
d = a / b
Console.WriteLine(" Division of a / b is {0}", d)
'Use of \ Operator
c = a \ b
Console.WriteLine(" Similar to division Operator (return only integer value) of a - b is {0}", c)
'Use of Mod Operator
c = a Mod b
Console.WriteLine(" Modulus of a Mod b is {0}", c)
'Use of ^ Operator
c = a ^ b
Console.WriteLine(" Power of a ^ b is {0}", c)

Comparison Operator in VB.net
The Comparison Operator in VB.net compares the values of two variables or operands for a variety of conditions, including greater, less than, or equal, etc., and depending on the condition, it produces a Boolean value of true or false.
The following table shows all the Comparison Operators in VB.net.
| Comparison Operator in VB.net | Description | Example |
|---|---|---|
| = | It checks whether the value of the two operands is equal; If yes, it returns a true value, otherwise it shows False. | (A = B) |
| <> | It is a Non-Equality Operator that checks whether the value of the two operands is not equal; it returns true; otherwise, it shows false. | (A <> B), check Non-Equality |
| > | A greater than symbol or Operator is used to determine whether the value of the left operand is greater than the value of the right operand; If the condition is true, it returns TRUE; otherwise, it shows FALSE value. | (A > B); if yes, TRUE,Else FALSE |
| < | It is a less than symbol which checks whether the value of the left operand is less than the value of the right operand; If the condition is true, it returns TRUE; otherwise, it shows FALSE value. | (A < B); if the condition is true, returns TRUE else FALSE |
| >= | It is greater than equal to which checks two conditions whether the first operand is greater than or equal to the second operand; if yes, it returns TRUE; otherwise, it shows False. | A >= B |
| <= | This symbol represents less than equal to which determines the first operand is less than or equal to the second operand, and if the condition is true, it returns TRUE; otherwise, it shows FALSE. | A <= B |
| Is | The Is Operator is used to validate whether the two objects reference the same variable or object; If the test is true, it returns True; otherwise, the result is False. In short, it checks the equality of the objects. An Is Operator is also used to determine whether the object refers to a valid object. | result = obj1 Is obj2 |
| IsNot | The IsNot Operator is similar to Is Operator, except that the two object references the different object; if yes, the result is True; otherwise, the result is False. | Result = obj1 IsNot obj2 |
| Like | The Like Operator is used to check the pattern expression of string variable; And if the pattern matched, the result is True; otherwise, it returns False. | result = string Like the pattern, the pattern represents the series of characters used by Like Operator. |
Example Program of VB.net Comparison Operator:
Imports System
Module Comparison_Operator
Sub Main()
'declaration of Integer, Object and String Data Type variables
Dim x As Integer = 5
Dim y As Integer = 10
Dim Result, obj, obj2 As Object
Dim str, str2 As String
str = "ITSOURCECODE"

Logical/Bitwise Operators in VB.net
The logical and bitwise Operators in VB.net 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 operands A and B, where A is True, and B is False.
The following table shows all the Logical/Bitwise Operators in VB.net.
| Logical/Bitwise Operators in VB.net | Description | Example |
|---|---|---|
| And | The And Operator represents, whether both the operands are true; the result is True. | (A And B), result = False |
| Or | It is an Or Operator that returns a true value; if anyone operand is true from both the operands. | (A Or B), result = True |
| Not | The Not Operator is used to reverse the logical condition. For example, if the operand’s logic is True, it reveres the condition and makes it False. | Not A OrNot (A And B) is True |
| Xor | It is an Exclusive OR Operator that represents, whether both the expression is true or false, the result is True; otherwise, the result is False. | A Xor B is True |
| AndAlso | It is a logical AND Operator that performs short-circuit operation on the variables, and if both the operands are true, the result is True else the result is False. | A AndAlso B = Falase |
| OrElse | It is a logical OR Operator that perform short-circuit operation on Boolean data. If anyone of the operand is true, the result is True else the result is False. | A Or Else B = True |
| IsFalse | The IsFalse Operator is used to determine whether an expression is False. | |
| IsTrue | The IsTrue Operator is used to determine whether an expression is True. |
Example Program of VB.net Logical/Bitwise Operators:
Imports System
Module Logic_Bitwise
Sub Main()
Dim A As Boolean = True
Dim B As Boolean = False
Dim c, d As Integer
c = 10
d = 20
'Use of And Operator
If A And B Then
Console.WriteLine(" Operands A And B are True")
End If
'Use of Or Operator
If A Or B Then
Console.WriteLine(" Operands A Or B are True")
End If
'Use of Xor Operator
If A Xor B Then
Console.WriteLine(" Operands A Xor B is True")
End If
'Use of And Operator

Console.WriteLine(" Operands c And d is True")
End If
'Use of Or Operator
If c Or d Then
Console.WriteLine(" Operands c Or d is True")
End If
'Use of AndAlso Operator
If A AndAlso B Then
Console.WriteLine(" Operand A AndAlso B is True")
End If
'Use of OrElse Operator
If A OrElse B Then
Console.WriteLine(" Operand A OrElse B is True")
End If
'Use of Not Operator
If Not (A And B) Then
Console.WriteLine(" Output of Not (A And B) is True")
End If
Console.WriteLine(" Press any key to exit?")
Console.ReadKey()
End Sub
End Module When the above code is compiled and executed, it produces the following result:
Operands A Or B are True
