Throwing an Exception in VB.net

By: Steven Holzner Viewed: 153308 times  Printer Friendly Format    


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()
        Try
            Throw New OverflowException()
        Catch e As Exception
            System.Console.WriteLine(e.Message)
        End Try
    End Sub
End Module
Tip 

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.
