详解C# Socket简单例子(服务器与客户端通信)

时间:2021-10-31 03:36:53

这个例子只是简单实现了如何使用 Socket 类实现面向连接的通信。

注意:此例子的目的只是为了说明用套接字写程序的大概思路,而不是实际项目中的使用程序。在这个例子中,实际上还有很多问题没有解决,如消息边界问题、端口号是否被占用、消息命令的解析问题等。。

下面是两个程序的代码,(两个程序均为控制台程序)

先发服务端的(Server)完整代码如下:

引入命名空间:

?

using System.Net.Sockets;
using SystemNet;
using SystemThreading;

namespace SocketServer
{
  class Program
  {
    private static byte[] result = new byte[1024];
    private static int myProt = 8885;  //端口
    static Socket serverSocket;
    static void Main(string[] args)
    {
      //服务器IP地址
      IPAddress ip = IPAddressParse("1");
      serverSocket = new Socket(AddressFamilyInterNetwork, SocketTypeStream, ProtocolTypeTcp);
      serverSocketBind(new IPEndPoint(ip, myProt)); //绑定IP地址:端口
      serverSocketListen(10);  //设定最多10个排队连接请求
      ConsoleWriteLine("启动监听{0}成功", serverSocketLocalEndPointToString());
      //通过Clientsoket发送数据
      Thread myThread = new Thread(ListenClientConnect);
      myThreadStart();
      ConsoleReadLine();
    }
 
    /// <summary>
    /// 监听客户端连接
    /// </summary>
    private static void ListenClientConnect()
    {
      while (true)
      {
        Socket clientSocket = serverSocketAccept();
        clientSocketSend(EncodingASCIIGetBytes("Server Say Hello"));
        Thread receiveThread = new Thread(ReceiveMessage);
        receiveThreadStart(clientSocket);
      }
    }
 
    /// <summary>
    /// 接收消息
    /// </summary>
    /// <param name="clientSocket"></param>
    private static void ReceiveMessage(object clientSocket)
    {
      Socket myClientSocket = (Socket)clientSocket;
      while (true)
      {
        try
        {
          //通过clientSocket接收数据
          int receiveNumber = myClientSocketReceive(result);
          ConsoleWriteLine("接收客户端{0}消息{1}", myClientSocketRemoteEndPointToString(), EncodingASCIIGetString(result, 0, receiveNumber));
        }
        catch(Exception ex)
        {
          ConsoleWriteLine(exMessage);
          myClientSocketShutdown(SocketShutdownBoth);
          myClientSocketClose();
          break;
        }
      }
    }
  }
}

以上是服务端(server)的完整代码。

客户端(Client)的完整代码如下:

using SystemNetSockets;
using SystemThreading;

namespace SocketClient
{
  class Program
  {
    private static byte[] result = new byte[1024];
    static void Main(string[] args)
    {
      //设定服务器IP地址
      IPAddress ip = IPAddressParse("1");
      Socket clientSocket = new Socket(AddressFamilyInterNetwork, SocketTypeStream, ProtocolTypeTcp);
      try
      {
        clientSocketConnect(new IPEndPoint(ip, 8885)); //配置服务器IP与端口
        ConsoleWriteLine("连接服务器成功");
      }
      catch
      {
        ConsoleWriteLine("连接服务器失败,请按回车键退出!");
        return;
      }
      //通过clientSocket接收数据
      int receiveLength = clientSocketReceive(result);
      ConsoleWriteLine("接收服务器消息:{0}",EncodingASCIIGetString(result,0,receiveLength));
      //通过 clientSocket 发送数据
      for (int i = 0; i < 10; i++)
      {
        try
        {
          ThreadSleep(1000);  //等待1秒钟
          string sendMessage = "client send Message Hellp" + DateTimeNow;
          clientSocketSend(EncodingASCIIGetBytes(sendMessage));
          ConsoleWriteLine("向服务器发送消息:{0}" + sendMessage);
        }
        catch
        {
          clientSocketShutdown(SocketShutdownBoth);
          clientSocketClose();
          break;
        }
      }
      ConsoleWriteLine("发送完毕,按回车键退出");
      ConsoleReadLine();
    }
  }
}

编译成功后,先运行 服务端(server),再运行客户端(client)即可达到通信效果。

该程序已在局域网测试通过。(192.168.X.X)

若编译失败,可到下面的地址下载项目文件:demo
