Throwing an Exception

You can throw an exception using the Throw statement, and you can also rethrow a caught exception using the Throw statement. Here's an example where I'm explicitly throwing an overflow exception:

Module Module1
    Sub Main()
            Throw New OverflowException()
        Catch e As Exception
        End Try
    End Sub
End Module

In fact, it's even possible to mix structured and unstructured exception handling to some extent—if you're using unstructured exception handling, you can get an exception object with the Err object's GetException method and throw that exception in a Try block.
