How to detect incoming network transfers in windows (preferably in c#)

I was wondering if anyone knows how (or even if it is possible) to monitor and trigger an action when a computer running windows (7-8) starts reciving a file transfer from over the network onto one of its drives.

Bonus points if I can find out how big the file is that the other guy is placing on my machine and how much is done etc...

I want to know if there is any API in windows, or snippit of code, or some other API that provides any of this functionality.

I still want to be able to recive files, I just want to manage them better. I am on a network with over 90 computers and this software that I wish to write would be running on most of them.

Of course you can (after all it's what an Antivirus program does) but it's NOT easy and probably you'll see it's more comfortable to do in C than in C#. I'm sure there's a .NET porting of WinPCap anyway you can always P/Invoke.

Start reading about Network Monitor SDK on MSDN. It's not an easy task, you have to capture a specific set of frames, you may use a Network Packet Monitor to inspect the content and the type of the packets you have to capture and parse.

I'm not sure but you may take a look to QoS API (start reading this article), it should provide something you can use.
