实现UDP可靠文件传输

在网上搜到的C#实现的UDP文件传输代码，分享给大家。局域网下速度能达到5,6M，效率还可以

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

namespace ReceiveFileDemo
{
    internal class ControlTag
    {
        private string _md5;
        private string _fileName;
        private IPEndPoint _remoteIP;

        public ControlTag（
            string md5
            string fileName
            IPEndPoint remoteIP）
        {
            _md5 = md5;
            _fileName = fileName;
            _remoteIP = remoteIP;
        }

        public string MD5
        {
            get { return _md5; }
            set { _md5 = value; }
        }

        public string FileName
        {
            get { return _fileName; }
            set { _fileName = value; }
        }

        public IPEndPoint RemoteIP
        {
            get { return _remoteIP; }
            set { _remoteIP = value; }
        }
    }
}
