SharpPcap is a fully managed, cross-platform .NET library for capturing packets from live network devices and reading/writing pcap capture files. It supports libpcap on Linux/macOS and Npcap/WinDivert on Windows, with BPF filtering and high-performance ReadOnlySpan-based APIs.

Use cases

• capture packets from a network interface in c#
• read and parse pcap capture files in .net
• build a network traffic monitor in c#
• filter packets with berkeley packet filter expressions
• write captured packets to a pcap file
• list available network devices in .net
• sniff packets cross-platform on windows mac and linux

When to choose

• you need packet capture in a .NET application across Windows, macOS, and Linux
• you want to read or write pcap/pcap-ng capture files from managed code
• you need BPF-based packet filtering with a high-performance, allocation-conscious API

When to avoid

• you need packet dissection or protocol construction - use Packet.Net alongside it
• your project is not on .NET or .NET Framework
• you need high-level network analysis features rather than raw capture
