Question

基本纲要是......

1）我的应用程序启动Java进程并对其进行管理。

2）我在另一个线程中有一个TCP服务器，用户可以连接并发出Java进程理解的命令。

3）传递命令不是问题是streamWriter.WriteLine（cmd）;但得到回应证明是困难的。

通过RedirectStandardError进入的下一行（由于某种原因它使用此而不是输出）应该是回复，但我无法弄清楚如何在我的TCP服务器的线程中访问它。

这就是我的TCP服务器的功能，它需要获得回复并将其打印出来。我怎么能这样做呢？

    static void AcceptClient(IAsyncResult ar)
    {
        TcpListener rconListener = ar.AsyncState as TcpListener;
        TcpClient rconClient = rconListener.EndAcceptTcpClient(ar);
        Console.WriteLine("New client: " + rconClient.Client.RemoteEndPoint.ToString());

        NetworkStream ns = rconClient.GetStream();

        // Loop while client is Connected
        while (rconClient.Connected)
        {
            byte[] buff = new byte[4096];
            List<byte> msg = new List<byte>();
            int total = 0;

            while (true)
            {
                int read = ns.Read(buff, 0, buff.Length);
                if (read <= 0)
                    break;

                msg.AddRange(buff);
                total += read;

                if (read < buff.Length)
                    break;
            }
            if (msg.Count <= 0)
            {
                Console.WriteLine("Lost connection: " + rconClient.Client.RemoteEndPoint.ToString());
                rconClient.Close();
                break;
            }

            int len = BitConverter.ToInt32(msg.ToArray(), 0);
            int seq = BitConverter.ToInt32(msg.ToArray(), 4);

            PacketType packetType = (PacketType)BitConverter.ToInt32(msg.ToArray(), 8);
            List<byte> response = new List<byte>();


            // RCON Execute Command
            if (packetType == PacketType.ServerData_ExecCommand_AuthResponse)
            {
                string srvcmd = ReadString(msg.ToArray(), 12);
                Console.WriteLine("RCON: " + srvcmd);

                response.AddRange(BitConverter.GetBytes((int)seq));
                response.AddRange(BitConverter.GetBytes((int)PacketType.ServerData_ResponseValue));

                string[] cmdargs = srvcmd.Split(new char[] { ' ' });

                if (cmdargs[0] == "rcon_password")
                {
                    ServerSettings.RCONPassword = cmdargs[1];
                    response.AddRange(Encoding.ASCII.GetBytes("RCON Password succesfully changed to " + cmdargs[1]));
                }
                else if (cmdargs[0] == "date")
                {
                    response.AddRange(Encoding.ASCII.GetBytes(DateTime.Now.ToString()));
                }
                else
                {
                    Program.SendRCONCmd(cmdargs[0]);
                }


                response.AddRange(new byte[] { 0x20, 0x0a }); //LF
                response.Add(0x0);
                response.Add(0x0);
                response.InsertRange(0, BitConverter.GetBytes((response.Count)));
                ns.Write(response.ToArray(), 0, response.Count);
            }
        }
    }
