说明：  SharpPcap 是一个.NET 环境下的网络包捕获框架，基于著名的 pcap/WinPcap 库开发。提供了捕获、注入、分析和构建的功能，适用于 C# 和 VB.NET 开发语言。
(The purpose of SharpPcap is to provide a framework for capturing, injecting and analyzing network packets for .NET applications. The following list illustrates the features currently supported by SharpPcap: Single assembly for Microsoft .NET and Mono platforms on Windows (32 or 64bit), Linux (32 or 64bit) and Mac. High performance- SharpPcap can capture fast enough to keep up with+3MB/s scp transfer rates WinPcap extensions are partially supported Setting the kernel buffer size Injecting packets using send queues Collecting network statistics on a given network interface Enumerating and showing details about the physical network interface on a Windows machine. Capturing low-level network packets going through a given interface. Analyzing and parsing the following protocols: Ethernet, ARP, IP (IPv4 and IPv6), TCP, UDP, ICMP, IGMP. Injecting low-level network packets on a given interface. Handling (reading and writing) offline packet capture files. Retrieving ad)
