最近在一个项目中，涉及到了C#的程序和一个C++的程序进行UDP交互数据的，所以就连续写了两个模块。希望能对大家有所帮助：

使用方法：

UDPServerService.cs

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Net.Sockets;

namespace UDPServerCSharp
{
    public class UdpState
    {
        public IPEndPoint e = null;
        public UdpClient u = null;
    }
    class UDPServerService
    {
        static UdpState us = new UdpState();
        static public void StartService(int _port)
        {
            IPEndPoint ipep = new IPEndPoint(IPAddress.Any,_port);
            UdpClient uc = new UdpClient(ipep);
            us.u = uc;
            us.e = ipep;
            uc.BeginReceive(new AsyncCallback(RecvCallback), us);
        }

static void RecvCallback(IAsyncResult ar)
        {
            UdpClient _uc = ((UdpState)ar.AsyncState).u;
            Byte[] recvBytes = _uc.EndReceive(ar, ref  ((UdpState)ar.AsyncState).e);
            _uc.BeginReceive(new AsyncCallback(RecvCallback), ar.AsyncState);
            string receiveString = Encoding.ASCII.GetString(recvBytes);
            ParseStr(receiveString);
        }

static void ParseStr(string _str)
        {
            Console.WriteLine(DateTime.Now.ToString() + "==" + _str);
        }
    }
}
