public void WriteData(string data)
{            try
            {
            client = new TcpClient();
            IPAddress ip = IPAddress.Parse(IP);
            client.Connect(ip, port);
            
              Byte[] mybytes = Encoding.ASCII.GetBytes(data);
              stream = client.GetStream();
              stream.Write(mybytes, 0, mybytes.Length);
            }
            catch (SocketException e)
            {
                isFail = true;
                text = e.ErrorCode + "连接失败！" + e.ToString();
            }
}
为什么执行到client.Connect(ip, port);会抱如下错误:
未处理
  Message="由于目标计算机主动拒绝，未能建立连接"
  ErrorCode=10061
  NativeErrorCode=10061

我用的IP是127.0.0.1 端口是6000

我看见有2个IP
一个是192.168.1.11
一个是192.168.5.101
我用了上面那个!没有异常发生
可服务器端却没有收到客户端发出的数据,又一个疑问出来了?
我的服务器端是这样写的:

static void Main(string[] args)
        {
            string s=Dns.GetHostName();//获得本机名
            Console.WriteLine(s);
            IPHostEntry address = Dns.GetHostEntry(s);//获得本机IP
            IPAddress[] my = address.AddressList;//获得本机IP数组，多个IP
            foreach (IPAddress i in my)//把本机所有IP打印出来
            {
                Console.WriteLine(i);
            }
            IPAddress IP = IPAddress.Parse("192.168.1.11");//socket://220.248.36.5
             int port = 6000;

            TcpListener server = new TcpListener(IP, port);
            server.Start();

            Console.WriteLine("等待客户机连接");
            while (true)
            {               
                Socket socket = server.AcceptSocket();
                //这里没有反应 为什么?????????????????????
                Console.WriteLine("服务器接受连接");
                try
                {                    
                    byte[] buff = new byte[1024];
                    int length = socket.Receive(buff);
                    Console.WriteLine("接受到数据！");
                    string data = Encoding.ASCII.GetString(buff, 0, length);
                    Console.WriteLine(data);
                }
                catch (Exception e)
                {
                    Console.WriteLine("客户机离开");
                    socket.Close();
                    break;
                }
            }
             Console.ReadLine();
}
