c# - Do I need to dispose the FileStream object?

Question

I am pretty depressed by my programming knowledge but do we really need to dispose FileStream Object ?

Reason I am asking is because code is throwing "File being used by another process" exception once in 100 cases and for a moment as if i try again(to download file using file stream) it works fine.

Please refer to this question for code.

Since it only happening once in 100 or so making me so confused and it's happening on production server so can't debug at all, but works perfectly on my development machine...

Answer 1

Of course, you need to dispose everything that is disposable, unless you have very good reason to not to dispose.

Put everything into a using block by default. If you call Close manually this is a code smell.
