How to detect file copy over local network with C#?

I've to create a simple application with .NET Framework that detects when a remote user copy some file from the machine that the application will run on.

Eg.

• Machine1 (The application will run here)
• Machine2

A user on the Machine2 access a shared directory on the Machine1 and copies some files to some Machine2 directory.

I need log the file name that was copied and the IP/DNS that request the copy.

Is there some Windows Message to do it?

Or even any IO class?

A requirement is that I have to do this through a custom application.
