Question

我收到TcpClient未连接的错误，我无法将信息发送到非活动的套接字。我想知道这段代码有什么问题吗？错误：未连接的套接字上不允许这种类型的连接。

SERVER:
public List<TcpClient> clients = new List<TcpClient>();

  On client connection:
  Socket s = currClient.Client;
  clients.Add(currClient.Client);

When Sending Client Info
   Stream sendData = clients[0].GetStream();
        ASCIIEncoding text = new ASCIIEncoding();
        byte[] clientInfoByte = text.GetBytes("msg");
        sendData.Write(clientInfoByte, 0, clientInfoByte.Length);
        sendData.Close();

客户端：

        Thread thr = new Thread(commands);
        thr.Start();
    }
    public static void commands()
    {
        Stream cmds = me.GetStream();
        while (true)
        {
            byte[] b = new byte[100];
            Socket s = me.Client;
            int k = s.Receive(b);
            string ClientInfo = "";
            string command = System.Text.Encoding.ASCII.GetString(b);

            if (command == "msg")
            {
                MessageBox.Show("Command Recieved!");
            }
        }
    }

在您的服务器中创建一个TcpListener＆＃34; listener＆＃34;并使用以下方法接受传入连接：

listener.BeginAcceptTcpClient(
    new AsyncCallback(DoAcceptTcpClientCallback), 
    listener);

然后在您的回调中，您将获得TcpClient将数据发送到

// Process the client connection.       
public static void DoAcceptTcpClientCallback(IAsyncResult ar) 
{
    TcpListener listener = (TcpListener) ar.AsyncState;

    TcpClient client = listener.EndAcceptTcpClient(ar);

    //add to your client list
    clients.Add(client);
  }

将TCP数据发送到C＃中的特定TcpClient
