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

With finally, you can clean up resources, even if your catch statement throws the exception up to the calling program. With your example containing the empty catch statement, there is little difference. However, if in your catch, you do some processing and throw the error, or even just don't even have a catch at all, the finally will still get run.
