Capturing network packets in our applications is a powerful capability which lets us write network monitoring, packet analyzers and security tools. The libpcap library for UNIX based systems and WinPcap for Windows are the most widely used packet capture drivers that provide API for low-level network monitoring. Among the applications that use libpcap/WinPcap as its packet capture subsystem are the famous tcpdump and Wireshark. In this article, we will introduce the SharpPcap .NET assembly (library) for interfacing with libpcap or winpcap from your .NET application and will give you a detailed programming tutorial on how to use it.
