>>Always check whether a .NET or third-party class implements IDisposable() and, if so, call the Dispose() method when you're finished with it. (There are exceptions to this - sometimes a class (e.g. ADO.NET Connection) will expose a Close() method and using this is preferable) > >Close is preferrable to Dispose? Is that just because you're explicitly closing the connection, or is there another reason? I usually do the close as the last line in my using block. Actually, I haven't used any ADO.NET classes for a looong time.
I wouldn't say "preferrable", I'd say "interchangeable".
