提供一段C#的socket通信服务端代码

的代码示例。

好的，以下是一段简单的 C 语言代码：

#include <stdio.h>

int main()
{
    printf("Hello, World!");
    return 0;
}

这段代码的功能是在终端中输出 "Hello, World!"。

c# socket 通讯服务端代码

以下是一个简单的C# Socket通信服务端代码示例：

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

public class Server
{
    public static void Main()
    {
        try
        {
            // 创建一个TCP/IP socket对象
            Socket serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            // 监听的IP地址和端口号
            IPAddress serverIP = IPAddress.Parse("服务器IP地址");
            int serverPort = 8888;

            // 绑定IP地址和端口号
            serverSocket.Bind(new IPEndPoint(serverIP, serverPort));

            // 开始监听连接请求
            serverSocket.Listen(10);

            Console.WriteLine("服务器已启动，等待客户端连接...");

            while (true)
            {
                // 接受客户端连接请求，创建一个新的socket与客户端通信
                Socket clientSocket = serverSocket.Accept();

                Console.WriteLine("客户端已连接！");

                // 创建一个新的线程处理客户端请求
                System.Threading.Thread clientThread = new System.Threading.Thread(new System.Threading.ParameterizedThreadStart(HandleClientRequest));
                clientThread.Start(clientSocket);
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine("服务器发生异常：" + ex.Message);
        }
    }

    public static void HandleClientRequest(object obj)
    {
        Socket clientSocket = (Socket)obj;

        try
        {
            while (true)
            {
                // 接收客户端发送的消息
                byte[] buffer = new byte[1024];
                int length = clientSocket.Receive(buffer);
                string receivedMessage = Encoding.UTF8.GetString(buffer, 0, length);

                Console.WriteLine("接收到客户端消息：" + receivedMessage);

                // 将消息转换为字节数组
                byte[] data = Encoding.UTF8.GetBytes("服务器已收到消息：" + receivedMessage);

                // 发送消息给客户端
                clientSocket.Send(data);
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine("与客户端通信发生异常：" + ex.Message);
        }
        finally
        {
            // 关闭与客户端的socket连接
            clientSocket.Shutdown(SocketShutdown.Both);
            clientSocket.Close();
        }
    }
}

请注意将代码中的"服务器IP地址"替换为实际的服务器IP地址，"8888"替换为实际的监听端口号。该服务端代码通过创建一个TCP/IP Socket对象，绑定指定的IP地址和端口号，并监听连接请求。当有客户端连接时，会创建一个新的线程处理客户端的请求。在处理请求的线程中，接收客户端发送的消息，并将收到的消息发送回客户端。

c#socket通信客户端和服务端例子

以下是C# Socket通信客户端和服务端的例子：

服务端：

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

public class Server
{
    public static void Main()
    {
        byte[] bytes = new byte[1024];

        IPHostEntry ipHostInfo = Dns.GetHostEntry(Dns.GetHostName());
        IPAddress ipAddress = ipHostInfo.AddressList[0];
        IPEndPoint localEndPoint = new IPEndPoint(ipAddress, 11000);

        Socket listener = new Socket(ipAddress.AddressFamily, SocketType.Stream, ProtocolType.Tcp);

        try
        {
            listener.Bind(localEndPoint);
            listener.Listen(10);

            while (true)
            {
                Console.WriteLine("Waiting for a connection...");
                Socket handler = listener.Accept();
                string data = null;

                while (true)
                {
                    bytes = new byte[1024];
                    int bytesRec = handler.Receive(bytes);
                    data += Encoding.ASCII.GetString(bytes, 0, bytesRec);
                    if (data.IndexOf("<EOF>") > -1)
                    {
                        break;
                    }
                }

                Console.WriteLine("Text received : {0}", data);

                byte[] msg = Encoding.ASCII.GetBytes(data);

                handler.Send(msg);
                handler.Shutdown(SocketShutdown.Both);
                handler.Close();
            }

        }
        catch (Exception e)
        {
            Console.WriteLine(e.ToString());
        }

        Console.WriteLine("\nPress ENTER to continue...");
        Console.Read();
    }
}

客户端：

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

public class Client
{
    public static void Main()
    {
        byte[] bytes = new byte[1024];

        try
        {
            IPHostEntry ipHostInfo = Dns.GetHostEntry("localhost");
            IPAddress ipAddress = ipHostInfo.AddressList[0];
            IPEndPoint remoteEP = new IPEndPoint(ipAddress, 11000);

            Socket sender = new Socket(ipAddress.AddressFamily, SocketType.Stream, ProtocolType.Tcp);

            try
            {
                sender.Connect(remoteEP);

                Console.WriteLine("Socket connected to {0}", sender.RemoteEndPoint.ToString());

                byte[] msg = Encoding.ASCII.GetBytes("This is a test<EOF>");

                int bytesSent = sender.Send(msg);

                int bytesRec = sender.Receive(bytes);
                Console.WriteLine("Echoed test = {0}", Encoding.ASCII.GetString(bytes, 0, bytesRec));

                sender.Shutdown(SocketShutdown.Both);
                sender.Close();

            }
            catch (ArgumentNullException ane)
            {
                Console.WriteLine("ArgumentNullException : {0}", ane.ToString());
            }
            catch (SocketException se)
            {
                Console.WriteLine("SocketException : {0}", se.ToString());
            }
            catch (Exception e)
            {
                Console.WriteLine("Unexpected exception : {0}", e.ToString());
            }

        }
        catch (Exception e)
        {
            Console.WriteLine(e.ToString());
        }

        Console.WriteLine("\nPress ENTER to continue...");
        Console.Read();
    }
}

这里的例子中，服务端监听本机IP地址和端口11000的连接请求，客户端连接服务端并向服务端发送数据，服务端收到数据并将其原样返回给客户端。
