There's plenty to say about the IDisposable interface and the using statement, but you probably don't have time to read it all (and I don't have time to write it all!), so I'm going to try to keep this short and simple.
First, let's make sure we're all on the same page. If you're not familiar with the relevant concepts, please take a moment to learn about .NET Garbage Collection, the IDisposable interface, the using statement, and the use of objects that implement IDisposable. (If you're a bibliophile, I understand that the book "Framework Design Guidelines: Conventions, Idioms, and Patterns for Reusable .NET Libraries" (ISBN 0321246756) contains additional material in section 10.3, "Dispose Pattern".)
Now that we're all familiar with the concepts, I'd like to call attention to a few things:
With these points in mind, I propose following guidelines whenever dealing with an object that implements the IDisposable interface:
Conveniently, the using statement makes it easy to do *all* of these things! The using statement is a simple programming construct that's very readable and that helps your code perform reliably, predictably, and efficiently. It doesn't get much better than that, so if you aren't already, please start using using today!
