In visual basic, the Exit statement is useful to terminate the execution of loops (for, while, do-while, etc.) and transfers the control immediately to the next statements that follow a terminated loops or statements.
In visual basic, we can also use Exit statement in nested loops to stop or terminate the execution of inner loops based on our requirements.
Following is the syntax of defining the Exit statement in a visual basic programming language.
In our applications, we can use Exit statement with Do, For, Function, Property, etc. to stop or terminate the execution of a particular loop or statement based on our requirements.
Following is the pictorial representation of Exit statement process flow in a visual basic programming language.
Now, we will see how to use Exit statement in for loop, while loop, do-while loop to terminate the execution of loops in a visual basic programming language with examples.
In visual basic, by using Exit keyword we can stop the execution of for loop statement based on our requirements.
Following is the example of terminating the execution of for loop with Exit statement.
Module Module1
Sub Main()
For i As Integer = 1 To 4
If i = 3 Then Exit For
Console.WriteLine("i value: {0}", i)
Next
Console.WriteLine("Press Enter Key to Exit..")
Console.ReadLine()
End Sub
End Module
If you observe the above code, we used Exit statement to terminate the for loop whenever the variable i value equals to 3.
When we execute the above visual basic program, we will get the result as shown below.
If you observe the above result, whenever the variable i value equals to 3, automatically the for loop execution has stopped.
This is how we can use the Exit statement in for loop to terminate the execution of for loop based on our requirements.
In visual basic, we can exit or terminate the execution of while loop immediately by using Exit keyword.
Following is the example of using Exit keyword in a while loop to terminate the execution of loop in a visual basic programming language.
Module Module1
Sub Main()
Dim i As Integer = 1
While i < 4
Console.WriteLine("i value: {0}", i)
i += 1
If i = 2 Then Exit While
End While
Console.WriteLine("Press Enter Key to Exit..")
Console.ReadLine()
End Sub
End Module
If you observe the above example, whenever the variable (i) value become 2 we are terminating the while loop using Exit statement.
When we execute the above visual basic program, we will get the result as shown below.
This is how we can use the Exit statement with while loop to terminate the execution of loop based on our requirements.
In visual basic, we can exit or terminate the execution of the do-while loop immediately by using Exit keyword.
Following is the example of using Exit keyword in a do-while loop to terminate the execution of loop in a visual basic programming language.
Module Module1
Sub Main()
Dim i As Integer = 1
Do
Console.WriteLine("i value: {0}", i)
i += 1
If i = 2 Then Exit Do
Loop While i < 4
Console.WriteLine("Press Enter Key to Exit..")
Console.ReadLine()
End Sub
End Module
If you observe the above example, whenever the variable (i) value become 2 we are terminating the loop using Exit statement.
When we execute the above visual basic program, we will get the result as shown below.
This is how we can use the Exit statement in do-while loop to terminate the execution of loop based on our requirements.
This is how we can use the Exit statement in our visual basic applications to terminate the execution of loops or statements based on our requirements.
