Question

我希望我的服务器继续监听同一个客户端。它只听一次客户端。如何继续阅读客户端发送的数据。

           sk = new Socket(AddressFamily.InterNetwork, SocketType.Stream,ProtocolType.Tcp);
            sk.Bind(new IPEndPoint(IPAddress.Any, 5000));
            sk.Listen(-1);

            while (true)
            {
                try
                {

                    Socket client = sk.Accept();
                    NetworkStream ns = new NetworkStream(client);
                    byte[] buffer = new byte[32768];
                    using (MemoryStream ms = new MemoryStream())
                    {
                        while (true)
                        {
                            int read = ns.Read(buffer, 0, buffer.Length);
                            if (read <= 0)
                                break;
                            ms.Write(buffer, 0, read);
                        }
                    }
                    MemoryStream msi = new MemoryStream(buffer);
                    Image returnImage = Image.FromStream(msi);

                }
                catch (Exception)
                {

                }
            }

最后我找到了解决这个问题的方法

private void Form1_Load(object sender, EventArgs e)
    {
        serverSocket = new TcpListener(9361);
        clientSocket = default(TcpClient);
        Thread listen = new Thread(listenClients);
        listen.Start();

    }
//this will keep listening the clients
    public void listenClients()
    {
        int counter = 0;
        serverSocket.Start();
        counter = 0;
        while ((true))
        {
            counter += 1;
            clientSocket = serverSocket.AcceptTcpClient();

            Thread thread = new Thread(
                () => readClient(clientSocket));
            thread.Start();
        }
    }

    public  void broadcast(Image bmp)
    {
        pictureBox1.Image = bmp;
    }  //en
 //keep reading the client data
    private void readClient(TcpClient inClientSocket)
    {

        byte[] bytesFrom = new byte[65536];
        string dataFromClient = null;
        while ((true))
        {
            try
            {
                NetworkStream networkStream = inClientSocket.GetStream();
                networkStream.Read(bytesFrom, 0, (int)clientSocket.ReceiveBufferSize);
                MemoryStream ms = new MemoryStream(bytesFrom);
                Image returnImage = Image.FromStream(ms);
                broadcast(returnImage);
            }
            catch (Exception ex)
            {

            }
        } //end while
    } //end readClint

如何在c＃socket中保持客户端连接到服务器？
