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

It is purely syntactic sugar on top of a try-catch-finally block and a call to the Dispose method. It does not even necessarily define a lexical scope since you can hand it an instance variable. Basically, it makes your code cleaner and easier to maintain.
