Question

I want to develop a program in c# that can target and application or port’s traffic and tries to view that traffic.For example,I select example.exe program in my application and it gives me it’s network traffic data.
Is it possible?If so,give me some directions.
I’m trying not to use airPcap or winPcap or anything like these,because these libraries target the network card and I don’t know what type of interface card the user might be using.

Answer 1

You have to either capture packets where you receive a duplicate from the NIC (pcap), or route requests through your own application so you can inspect the live packet flow (proxy-like).

For a WinPcap implementation in C#, take a look at SharpPcap. For a proxy, see here.
