.net socket客户端实例代码分享

客户端代码

代码如下:

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Data;

using System.Net;

using System.Threading;

using System.Net.Sockets;

namespace W.Common

    public class CacheSocket

        public Socket skClient;

        public string ip = string.Empty;

        public int port = -1;

        public int netID;

        // public int timeSleep = 1;

        //每次接收发送的临时信息

        private byte[] sendData;//发送的信息

        private byte[] receiveData = new byte[1024];//接收信息

        private int receiveN;

        private bool isErr = false;

        //--------

        public CacheSocket(int pNetID)

        {

            this.netID = pNetID;

            GetConfig();

            Connection();

            Cmd("netid:" + this.netID);

        }

        public CacheSocket(int pNetID, string pIP, int pPort)

        {

            this.ip = pIP;

            this.port = pPort;

            Connection();

            Cmd("netid:" + pNetID);

        }

        public string Cmd(string key)

        {

            lock (this)//一个信息发送后再接收为一次完成过程

            {

                this.sendData = Encoding.UTF8.GetBytes(key);

                try
