Regardless of what terminates the using statement, an exception or just reaching the end of the block or whatever, Dispose() for the object created by the using will always be called.

That's the beaty about "using", you don't have to worry about cleaning up.

>>What you could do if the Socket class suports IDisposable is use a using statement, that way, you don't have to worry about writing a finnally block, the Scocket object will dispose itself.

>>>The contents of the code is not really important, but what can I use in the finally block to ensure that the object that I am trying to call the "clean-up" code for (in this case Close()) has been initialized? What if an error was thrown before the line Socket udpSocket = new Socket(...), I want to call Close() on the udpSocket in the finally block but only if the object udpSocket is defined.
