Throwing an Exception in

By: Steven Holzner in Tutorials on 2010-11-17  

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.
