Throw VS rethrow : same result?

Question

refering to a lot of documentation on the net, particularly on SO, eg : What is the proper way to re-throw an exception in C#? there should be a difference between \"throw e;\"

Answer 1

Use a debug build and you will see the difference more clearly. With a debug build the first run will show the location as the throw ex line and the second as originating from the actual call to BadGuy. Obviously the 'problem' is the call to BadGuy - not the throw ex line and you'll chase fewer ghosts with the direct throw; statement.

In a stack trace this shallow the benefits aren't as immediatley obvious, in a very deep stack you'll mask the actual source of the problem and loose some fidelity by manually throwing exception instead of using the built in re-throw statement.
