It's a question about best .net practise. I always caught and stored information about exceptions in all of my web and window forms applications as follows:
Is this the best way to handle exceptions? Or should I do something different in my next projects?

C++ exception handling is built upon three keywords: try, catch, and throw. throw − A program throws an exception when a problem shows up. This is done using a throw keyword. catch − A program catches an exception with an exception handler at the place in a program where you want to handle the problem.
I wouldn't add 1 & 2 unless I had some specific reason; for example to alter (wrap) the message; there is no need since exceptions will raise upwards anyway. And done incorrectly you can accidentally remove the all-important stack-trace (throw; vs throw ex; - the first being preferred).
