c# - 设置 tcp 服务器与 android 和 kinect 通信

Question

我正在制作一个带有 android 和 kinect 的双重应用程序。我希望能够从 kinect 向 android 应用程序发送通知。有人告诉我，完成此任务的最佳方法是设置一个简单的 tcp 服务器。我尝试使用此 <链接> 中的教程进行设置。然而，该教程对我来说描述性不够，我无法使其工作。发布它的人基本上发布了几段代码，没有任何关于组装它们的说明。我需要有人指导我设置此服务器，或者我需要一个指向详细教程的链接。我自己在网上搜索了几个小时，但没有找到任何有用的东西，这就是我在这里问的原因。

以下是我认为他在该教程中所说的内容：

using System;
using System.Text;
using System.Net.Sockets;
using System.Threading;
using System.Net;

namespace TCPServerTutorial
{
  class Server
  {
    private TcpListener tcpListener;
    private Thread listenThread;

    public Server()
    {
      this.tcpListener = new TcpListener(IPAddress.Any, 3000);
      this.listenThread = new Thread(new ThreadStart(ListenForClients));
      this.listenThread.Start();
    }


    private void HandleClientComm(object client)
    {
      TcpClient tcpClient = (TcpClient)client;
      NetworkStream clientStream = tcpClient.GetStream();

      byte[] message = new byte[4096];
      int bytesRead;

      while (true)
      {
        bytesRead = 0;

        try
        {
          //blocks until a client sends a message
          bytesRead = clientStream.Read(message, 0, 4096);
        }
        catch
        {
          //a socket error has occured
          break;
        }

        if (bytesRead == 0)
        {
          //the client has disconnected from the server
          break;
        }

        //message has successfully been received
        ASCIIEncoding encoder = new ASCIIEncoding();
        System.Diagnostics.Debug.WriteLine(encoder.GetString(message, 0, bytesRead));
      }

      tcpClient.Close();
    }

    private void ListenForClients()
    {
      this.tcpListener.Start();

      while (true)
      {
        //blocks until a client has connected to the server
        TcpClient client = this.tcpListener.AcceptTcpClient();

        //create a thread to handle communication
        //with connected client
        Thread clientThread = new Thread(new ParameterizedThreadStart(HandleClientComm));
        clientThread.Start(client);
      }
    }

    //you'll have to find a way to pass this arg
    private void SendBack(TcpClient tcpClient)
    {
    NetworkStream clientStream = tcpClient.GetStream();
    ASCIIEncoding encoder = new ASCIIEncoding();
    byte[] buffer = encoder.GetBytes("Hello Client!");

    clientStream.Write(buffer, 0 , buffer.Length);
    clientStream.Flush();
    }
  }
}

但这只是我。他只谈论过一个类，因此假设他的所有功能都在该类中是合乎逻辑的。

对于客户端代码，他几乎只是为您提供了一个函数的代码（当然是在 C# 中），它将一些字节发送到一个 IP 地址（也就是您的服务器正在运行的机器的 IP）。您可以将此函数放在任何 C# 类中，并以您希望的任何方式调用它。他已经硬编码了 IP 地址和要发送的消息，但这些很容易成为传递给函数的参数。

private void SendToServer(){
    TcpClient client = new TcpClient();

    //IP of the server: currently loopback, change to whatever you want
    IPEndPoint serverEndPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 3000);

    client.Connect(serverEndPoint);

    NetworkStream clientStream = client.GetStream();

    ASCIIEncoding encoder = new ASCIIEncoding();

    //Message being sent: "Hello Server!"
    byte[] buffer = encoder.GetBytes("Hello Server!");

    clientStream.Write(buffer, 0 , buffer.Length);
    clientStream.Flush();
}
