C# tcp 套接字定义客户端

Question

我正在尝试使用 Visual Studio 2010 设置一个 tcp .net 套接字网络。到目前为止它可以工作，我可以将客户端连接到它，但目前我无法定义连接的客户端。我需要一组已连接的客户端，这样我就可以更具体地说明我要流式传输给谁。

这是我的服务器代码，我正在从 http://www.codeproject.com/Articles/511814/Multi-client-per-one-server-socket-programming-in 复制所有这些代码

服务器代码

static TcpListener tcpListener = new TcpListener(25000);

    static void Listeners()
    {
        Socket socketForClient = tcpListener.AcceptSocket();
        if (socketForClient.Connected)
        {
            Console.WriteLine("Client:"+socketForClient.RemoteEndPoint+" now connected to server.");
            NetworkStream networkStream = new NetworkStream(socketForClient);

            System.IO.StreamWriter streamWriter =
            new System.IO.StreamWriter(networkStream);
            System.IO.StreamReader streamReader =
            new System.IO.StreamReader(networkStream);


            Console.WriteLine("type your message to be recieved by client:");
            string theString2 = Console.ReadLine();
            streamWriter.WriteLine(theString2);
            Console.WriteLine(theString2);
            streamWriter.Flush();

            while (true)
            {
                string theString = streamReader.ReadLine();
                Console.WriteLine("Message recieved by client:" + theString);
                if (theString == "exit")
                    break;
            }
            streamReader.Close();
            networkStream.Close();
            streamWriter.Close();


        }
        socketForClient.Close();
        Console.WriteLine("Press any key to exit from server program");
        Console.ReadKey();
    }

    public static void Main()
    {
        tcpListener.Start();
        Console.WriteLine("************This is Server program************");
        Console.WriteLine("Hoe many clients are going to connect to this server?:");
        int numberOfClientsYouNeedToConnect = int.Parse(Console.ReadLine());
        for (int i = 0; i < numberOfClientsYouNeedToConnect; i++)
        {
            Thread newThread = new Thread(new ThreadStart(Listeners));
            newThread.Start();
        }
    }

Answer 1

如果你想坚持使用原始 TCP 套接字，那么你可以将委托(delegate)/处理程序等传递给线程:

for (int i = 0; i < numberOfClientsYouNeedToConnect; i++)
{
     Thread newThread = new Thread(new ParameterizedThreadStart(Listeners));
     newThread.Start(i);
}

然后您的监听器需要采用一个对象 来匹配ParametrizedThreadStart see MSDN

但是，如果您正在开发两端(正如我评论的那样)，我会建议一些更抽象的东西，例如 ASP.NET SignalR或类似的情况。它增加了一些开销，但您可以在方便的抽象级别上获得服务器到客户端的通信，反之亦然。
