Hugo Estrada's House of Wonder

This may be one of the most useful pages explaining "using" in C#.

It seems that
a) Using is a try-finally clause without a catch
b) You must properly implement the IDispose() method, or its magic won't happen.

Now I can use this keyword. I have avoided it because it seems that I don't like magic. Now I will be able to use this construction since I know exactly what it does. Thanks, Peter Femiani , for taking the magic out of "using."
