VB exit sub

In VB, you can exit a sub procedure at any time by using Exit Sub statement. The Exit Sub statement is useful when you detect an invalid input and there is no reason to continue next code execution.

Module Module1
   Sub Main()
     readdate()
     Console.Read()


   End Sub
   Sub readdate()
     Console.WriteLine("Enter a date value:")
     Dim datestr = Console.ReadLine()
     If Not IsDate(datestr) Then ' If not a valid date format input then do not continue the next code
        Exit Sub
     Else
        Dim dv = Date.Parse(datestr)
        Console.WriteLine("You long date format is: " & FormatDateTime(dv, DateFormat.LongDate))
     End If

   End Sub
