Exits a procedure or block and transfers control immediately to the statement following the procedure call or the block definition.

Exit { Do | For | Function | Property | Select | Sub | Try | While }  

Exit Do
Immediately exits the Do loop in which it appears. Execution continues with the statement following the Loop statement. Exit Do can be used only inside a Do loop. When used within nested Do loops, Exit Do exits the innermost loop and transfers control to the next higher level of nesting.

Exit For
Immediately exits the For loop in which it appears. Execution continues with the statement following the Next statement. Exit For can be used only inside a For...Next or For Each...Next loop. When used within nested For loops, Exit For exits the innermost loop and transfers control to the next higher level of nesting.

Exit Function
Immediately exits the Function procedure in which it appears. Execution continues with the statement following the statement that called the Function procedure. Exit Function can be used only inside a Function procedure.

To specify a return value, you can assign the value to the function name on a line before the Exit Function statement. To assign the return value and exit the function in one statement, you can instead use the Return Statement.

Exit Property
Immediately exits the Property procedure in which it appears. Execution continues with the statement that called the Property procedure, that is, with the statement requesting or setting the property's value. Exit Property can be used only inside a property's Get or Set procedure.

To specify a return value in a Get procedure, you can assign the value to the function name on a line before the Exit Property statement. To assign the return value and exit the Get procedure in one statement, you can instead use the Return statement.

In a Set procedure, the Exit Property statement is equivalent to the Return statement.

Exit Select
Immediately exits the Select Case block in which it appears. Execution continues with the statement following the End Select statement. Exit Select can be used only inside a Select Case statement.

Exit Sub
Immediately exits the Sub procedure in which it appears. Execution continues with the statement following the statement that called the Sub procedure. Exit Sub can be used only inside a Sub procedure.

In a Sub procedure, the Exit Sub statement is equivalent to the Return statement.

Exit Try
Immediately exits the Try or Catch block in which it appears. Execution continues with the Finally block if there is one, or with the statement following the End Try statement otherwise. Exit Try can be used only inside a Try or Catch block, and not inside a Finally block.

Exit While
Immediately exits the While loop in which it appears. Execution continues with the statement following the End While statement. Exit While can be used only inside a While loop. When used within nested While loops, Exit While transfers control to the loop that is one nested level above the loop where Exit While occurs.

Do not confuse Exit statements with End statements. Exit does not define the end of a statement.

In the following example, the loop condition stops the loop when the index variable is greater than 100. The If statement in the loop, however, causes the Exit Do statement to stop the loop when the index variable is greater than 10.

        Dim index As Integer = 0
        Do While index <= 100
            If index > 10 Then
                Exit Do
            End If

            Debug.Write(index.ToString & " ")
            index += 1
        Loop

        Debug.WriteLine("")
        ' Output: 0 1 2 3 4 5 6 7 8 9 10 

The following example assigns the return value to the function name myFunction, and then uses Exit Function to return from the function.

    Function myFunction(ByVal j As Integer) As Double
        myFunction = 3.87 * j
        Exit Function
    End Function

The following example uses the Return Statement to assign the return value and exit the function.

        Function myFunction(ByVal j As Integer) As Double
            Return 3.87 * j
        End Function
