When are C# “using” statements most useful?

Question

So a using statement automatically calls the dispose method on the object that is being \"used\", when the using block is exited, right?

But when is this necessary/benef

Answer 1

They are useful in any situation when you want cleanup code to be called on an object deterministically and regardless of exceptions (since a using statement is really just a try/finally).

Most often they are used to clean up unmanaged resources but you can use them however you see fit.
