How to find the client network speed

I am sending a file from client to server. Both the client and server applications are running in the same machine. After a sending a file from client to server, now I need to show the time it will take to transfer the file from client to server in .Net. Same as copy box 开发者_如何转开发in windows xp.

Any idea would be appreciate.

You can remember the size of the file, and divide it by the time it took to transfer the file. This will give you a transfer speed estimate (for instance, kilobytes / second).
