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?

Answer 1

I don't think this is possible by default. But there are plenty of third party libraries that enable you to do that. Take a look at

• SharpPcap - A Packet Capture Framework for .NET
• Packet Capture and Analayzer
• Pcap.Net
