I have a very simple page with which a user uploads a file. Using only server-side C# (e.g. the code-behind), how can I measure the amount of time the user had to wait for the file to upload?

This is very difficult (well, it was in IIS6). You need to write an HttpModule to intercept the upload and handle it, then using the total size of the file coming in (it’s in the header of the request), calculate how many bytes per second you’re getting, and then you can calculate how much time is left.
However, you cannot do any of this with just the code-behind file — the file is already uploaded and available by the time the request gets to the asp.net handler.
