客戶端代碼

復(fù)制代碼 代碼如下:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Data;

using System.Net;

using System.Threading;

using System.Net.Sockets;

        public int netID;

        // public int timeSleep = 1;

        //每次接收發(fā)送的臨時信息

        private byte[] sendData;//發(fā)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;

            Connection();

        }

        public delegate void ReSocket_D();

        private void ReSocket(ReSocket_D d)

            if (isErr)

            {

                this.sendData = Encoding.UTF8.GetBytes("netid:" + this.netID);

                this.skClient.Send(this.sendData);

                this.receiveN = this.skClient.Receive(this.receiveData);

                if (Encoding.UTF8.GetString(this.receiveData, 0, this.receiveN) != "1")

                {

                }

                d();

                this.isErr = false;

            }

        }

        #region 獲取IP和端口

        private void GetConfig()

        {

            this.ip = "127.0.0.1";

            this.port = 1234;

        }

        #endregion

        #region 連接套接字

        private void Connection()

        {

            this.skClient = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            IPEndPoint ie = new IPEndPoint(IPAddress.Parse(this.ip), this.port);//服務(wù)器的IP和端口

            skClient.Connect(ie);

            byte[] data = new byte[7];

            this.receiveN = this.skClient.Receive(data);

            string s = Encoding.UTF8.GetString(data, 0, this.receiveN);

            if (s != "success")

            {

                throw new Exception("連接不成功" + s);

            }

        }

        #endregion

    }

}

使用方法

復(fù)制代碼 代碼如下:

 public static readonly CacheSocket cac=new CacheSocket(2);

 cac.Cmd("發(fā)送內(nèi)容");
