The GoTo statement transfers control unconditionally to a specified line in a procedure.
GoTo statement can branch only to lines in the procedure in which it appears.GoTo can refer to.The basic syntax of the GoTo statement looks like as shown below.
GoTo line
Place an identifier, followed by a colon, at the beginning of the line of source code.
Line1:
Labels can be used only on executable statements inside methods.
You cannot use a GoTo statement to branch from outside a For...Next, For Each...Next, SyncLock...End SyncLock, Try...Catch...Finally, With...End With, or Using...End Using construction to a label inside.
Within a Try...Catch...Finally construction, the following rules apply to branching with the GoTo statement.
| Block or region | Branching in from outside | Branching out from inside |
|---|---|---|
| Try block | Only from a Catch block of the same construction |
Only to outside the whole construction |
| Catch block | Never allowed | Only to outside the whole construction, or to the Try block of the same construction |
| Finally block | Never allowed | Never allowed |
The following example uses the GoTo statement to branch to line labels.
Module GoToStatement
Public Sub Example1()
Dim number As Integer = 1
Dim sampleString As String
If number = 1 Then
GoTo Line1
Else
GoTo Line2
End If
Line1:
sampleString = "Number equals 1"
GoTo LastLine
Line2:
sampleString = "Number equals 2"
LastLine:
Console.WriteLine(sampleString)
End Sub
End Module
