please help.

Not sure if I understood correctly what you are trying to do, but if it is to get the type of the exception that is being catch by the exception handling, then what you could do is simply put a Breakpoint on the Catch and look at the Local Variables panel on Debug mode when the execution get there to see more information. Another option would be to put a Rethrow on the Catch block.
