软件简介

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)]]
