Is there a list of common object that implement IDisposable for the using statement?

Question

I was wondering if there was some sort of cheat sheet for which objects go well with the using statement... SQLConnection, MemoryStream, etc.

Answer 1

A quick&dirty way of checking if a type implements IDisposable is to create an instance of it and check if the instance has a Dispose() member function. If it does then you can be 99% sure that it implements IDisposable.
