Packet.Net 介绍
Packet.Net 是一个.NET程序包，提供了剖析和构建网络数据包的功能。可以通过类的属性来调整各种数据包的参数。
示例代码：
using PacketDotNet;
// open the capture file
SharpPcap.LivePcapDevice dev = new SharpPcap.LivePcapDevice("SomeCapturedPackets.pcap");
// read a raw packet
rawPacket = dev.GetNextRawPacket();
// parse the packet
Packet p = Packet.ParsePacket((LinkLayers)rawPacket.LinkLayerType,
new PosixTimeval(rawPacket.Timeval.Seconds,
rawPacket.Timeval.MicroSeconds),
rawPacket.Data);
// print out the packet contents
Console.WriteLine(p);
输出信息：
[EthernetPacket: 00234D5BF88B -> 00183F7775D1 proto=IpV4 (0x800) l=14][IPv4Packet: 192.168.1.76 -> 72.14.204.83 HeaderLength=5 Protocol=TCP TimeToLive=64][TCPPacket: SourcePort: 59038 -> DestinationPort: 443 ack[218134930 (0xd007992)]]
