I'm not talking about closing the toilet lid (and not just putting the seat down as women seem to think is acceptable!).

Anyway...

I've just been pulling my hair out over why a zip file generated using SharpZipLib was being corrupted when returned from a webpage, saving to disk on the server worked flawlessly. The file sent to the client was approximately 7kb larger than the one saved on the server.

Now usually I use the using statement to dispose of any objects that use resources but for some reason I wasn't calling Response.Close() in my method (Close() just calls Dispose(true)).

What's even more annoying is there was the case of "it worked last week, why isn't it working anymore???". I don't remember putting Response.Close() in the first place, let alone deleting it at somepoint.

So please remember to Close() after you Flush(), it's only polite.
