Is there a low level Network library to sniff and change network traffic? [closed]

题

I am looking for a way to sniff network packets and encode them with C# (in summary: alter network traffic).

I don't know how to explain my request but I need something like "Keyboard Hook".

Is there any library or software in .net or Windows API?
