C# 根据MAC地址 监听IP数据报

Question

这个没做过 MARK 等高人回复

Answer 1

监听MAC地址？？如果是多网卡的话，感觉还是先找到对应MAC地址的IP地址，监听这个IP地址吧！

Answer 2

试试fastCSharpusing System;
using fastCSharp;namespace fastCSharp.demo.rawSocketListener
{
    class Program
    {
        /// <summary>
        /// 原始套接字监听
        /// </summary>
        /// <param name="args"></param>
        static void Main(string[] args)
        {
            using (fastCSharp.net.rawSocketListener rawSocket = new fastCSharp.net.rawSocketListener(getPacket, System.Net.IPAddress.Parse("192.168.1.100")))
            {
                Console.ReadKey();
            }
        }
        /// <summary>
        /// 数据包处理
        /// </summary>
        /// <param name="data">数据包</param>
        private static void getPacket(subArray<byte> data)

                        }
                        else Console.WriteLine("Unknown");
                        break;
