How do I automatically delete tempfiles in c#?

Question

What are a good way to ensure that a tempfile is deleted if my application closes or crashes? Ideally I would like to obtain a tempfile, use it and then forget about it.

Answer 1

You could P/Invoke CreateFile and pass the FILE_FLAG_DELETE_ON_CLOSE flag. This tells Windows to delete the file once all handles are closed. See also: Win32 CreateFile docs.
