Why is try {…} finally {…} good; try {…} catch{} bad?

Question

I have seen people say that it is bad form to use catch with no arguments, especially if that catch doesn\'t do anything:

StreamReader reader=new  StreamRead         


        

Answer 1

If you don't know what exception type to catch or what to do with it, there's no point in having a catch statement. You should just leave it for a higher-up caller that may have more information about the situation to know what to do.

You should still have a finally statement in there in case there is an exception, so that you can clean up resources before that exception is thrown to the caller.
