VB.NET GoTo Statement

In VB.NET, the GoTo statement is known as a jump statement. It is a control statement that transfers the flow of control to the specified label within the procedure. The GoTo statement uses labels that must be a valid identifier. The GoTo statement can be used in Select case, decision control statements, and loops.

Syntax:

Here, GoTo is a keyword, and label_1 is a label used to transfer control to a specified label statement in a program.

Now we will see how to use the GoTo statement in the loop, select case, or decision-making statement to transfer control to the specified label statement in the VB.NET program.

Use of GoTo statement in If Else

Example 1: Write a simple program to print whether the number is even or odd in GoTo Statement.

Goto_Statement.vb

Imports System
Module Goto_Statement
    Sub Main()
        'Declaration of local variable
        Dim num As Integer
        Console.WriteLine(" Enter the number :")
        num = Console.ReadLine ' Accept a number from the user
        If (num Mod 2 = 0) Then
            GoTo even ' Jump to even label
        Else
            GoTo odd   ' Jump to odd label
        End If
odd:
        Console.WriteLine(" It is an Odd number")

even:
        Console.WriteLine(" It is an Even number ")
        Console.WriteLine(" Press any key to exit...")
        Console.ReadKey()
    End Sub
End Module

Output:

In the above program, when we enter a number, it checks whether the number is even or odd. And if the number is odd, the GoTo statement will be encountered, and the control transfers to the odd statement Else the control transfer to the even statement.

Use of GoTo Statement in For Next loop

Example 2: Write a program to print the sum of the First ten numbers using the Goto Statement in VB.NET.

Goto_For.vb

Imports System
Module Goto_For
    Sub Main()
        'Declaration of local variable
        Dim i, n As Integer, Sum As Integer = 0

        ' Define For Loop Statement
        For i = 1 To 10
            Console.WriteLine(" Value of i is {0}", i)
            Sum = Sum + i 'At each iteration the value of i added to Sum
            If i = 5 Then
                n = i 'Assign i to n

                GoTo total_sum  ' Jump to total_sum
            End If
        Next
total_sum:
        Console.WriteLine(" Total sum is {0}", Sum)
        Console.WriteLine(" GoTo Encounter, when value of i = {0}", n)
        Console.WriteLine(" Press any key to exit...")
        Console.ReadKey()
    End Sub
End Module

Output:

In the above program, the For loop is executed till the given condition ( i = 1 To 10). And when the value of i is equal to 5, the GoTo statement will be encountered, and it transfers the control to total_sum so that the total sum of each iteration can be printed in the For loop.

Use of GoTo statement in Select Case Statement

Example 3: Write a simple program to print the days' names in select cases using the GoTo Statement.

Goto_Select.vb

Imports System
Module Goto_Select
    Sub Main()
        'Definition of local variable 
        Dim Days As String
        Days = "Thurs"
        Select Case Days

            Case "Mon"
Case1:

                Console.WriteLine(" Today is Monday")
            Case "Tue"
                Console.WriteLine(" Today is Tuesday")
            Case "Wed"
                Console.WriteLine("Today is Wednesday")
            Case "Thurs"
                Console.WriteLine("Today is Thursday")
                GoTo Case1
            Case "Fri"
                Console.WriteLine("Today is Friday")
            Case "Sat"
                Console.WriteLine("Today is Saturday")
            Case "Sun"
                Console.WriteLine("Today is Sunday")
            Case Else
                Console.WriteLine(" Something wrong")

        End Select
        Console.WriteLine("You have selected : {0}", Days)
        Console.WriteLine("Press any key to exit...")
        Console.ReadLine()
    End Sub
End Module

Output:

In the Select case statement, the value of Days Thurs will compare the values of all selected cases available in a program. If it matches any statement, it prints the particular statement and contains the GoTo statement that transfers control to defined case1: and then the following statement is executed.

Use of GoTo statement in While End Loop Statement

Example 4: Write a simple program to understand the use of GoTo statement in the While loop.

Goto_While.vb

Imports System
Module GoTo_While
    Sub Main()
        'Declaration and initialization of the local variable
        Dim i As Integer = 1, num As Integer
start1:
        'Definition of While Loop
        While i < 10
            If i = 6 Then
                num = i
                i += 1
                GoTo start1 'transfer control at start1
            End If
            Console.WriteLine(" Value of i is {0}", i)

            i += 1 ' Update the variable i by 1
        End While
        Console.WriteLine(" Control transfer at number {0}", num)

        Console.WriteLine(" Press any key to exit...")
        Console.ReadKey()
    End Sub
End Module
