使用unity UGUI 利用Socket 实现 多客户端通讯

unity  5.1.1  UGUI    VS2013

服务器端：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;

namespace SocketSever
{
    class Program
    {   static ListclientList =new List();  //建立连接的数组！！！！
        /// 

        /// 广播消息
        /// 
        /// 
        public  static void BroadcastMessage(string message)
    {   var notConnectedList = new List();
        foreach (var client in clientList)
        {
            if (client.Connected)
            {
                client.SendMessage(message);
            }
            else
            {
                notConnectedList.Add(client);
            }
        }
        foreach (var temp in notConnectedList)
        {
            clientList.Remove(temp);
        }
    }
        static void Main(string[] args)
        {
            int port = 6180;               //端口
            string host = "192.168.10.75"; //IP
            //创建终结点
            IPAddress ip = IPAddress.Parse(host);
            IPEndPoint ipe = new IPEndPoint(ip, port);

            //创建Socket并开始监听
            Socket TcpSever = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); 

//创建一个Socket对象，如果用UDP协议，则要用SocketTyype.Dgram类型的套接字
            TcpSever.Bind(ipe);                                                                            //绑定EndPoint对象(6180端口和ip地址)
            TcpSever.Listen(100);            //开始监听 监听数//接受到Client连接，为此连接建立新的Socket，并接受消息
         Console.WriteLine("等待客户端连接。。。。。");
                                             //死循环接受新的连接
            while(true){
            Socket temp = TcpSever.Accept();  //为新建立的连接创建新的Socket
            Console.WriteLine("有一个已经连接过来了！");
            Client client = new Client(temp); //把与客户的通讯交互逻辑做到Client 类里面（收发消息）
            clientList.Add(client);           //新的连接放入集合
            }


            //Console.WriteLine("建立连接");
            //string recvStr = "";
            //byte[] recvBytes = new byte[1024];
            //int bytes;
            //bytes = temp.Receive(recvBytes, recvBytes.Length, 0); //从客户端接受消息
            //recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);

            ////给Client端返回信息
            //Console.WriteLine("server get message:{0}", recvStr);    //把客户端传来的信息显示出来
            //string sendStr = "ok!Client send message successful!";
            //byte[] bs = Encoding.ASCII.GetBytes(sendStr);
            //temp.Send(bs, bs.Length, 0);                             //返回信息给客户端
            //temp.Close();
            //TcpSever.Close();
            //Console.ReadLine();
        }
    }
}

   

Client 类：

using System.Threading.Tasks;

        private Thread t;//建立线程
        private byte[] data=new byte[1024];//数据容器
        public Client(Socket s)
        {
            clientSocket = s;
            //启动一个线程处理接收客户端的数据
            t = new Thread(ReceiveMessage);
            t.Start();
        }
        private void ReceiveMessage()
        {
            while(true){
                //在接收数据之前 判断Socket连接是否断开
                if (clientSocket.Poll(10,SelectMode.SelectRead))
                {
                    clientSocket.Close();
                    break;//跳出循环 终止线程
                }
                try
                {
                    int length = clientSocket.Receive(data);
                    string message = Encoding.UTF8.GetString(data, 0, length);
                    //TODO:接收数据之后把数据分发到客户端
                    //广播这个消息！！！！！！！！！
                    Program.BroadcastMessage(message);
                    Console.WriteLine("客户端发来的消息：" + message);
                }
                catch (Exception ex) { Console.WriteLine("有一个退出了：" +"这是一个异常"); }
            }
        }
        /// 

        /// 分发出去
        /// 
        /// 
        public void SendMessage(string message)
        {
            byte[] data = Encoding.UTF8.GetBytes(message);
            clientSocket.Send(data);
        }
        public bool Connected
        {
            get { return clientSocket.Connected; }
        }
    }
}

unity 源码         客户端在关闭的时候没有关闭Socket连接，存在异常！！！！！
