.net socket代码

以下是使用C#编写的简单的Socket服务器和客户端代码：

服务器端代码：

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

namespace SocketServer
{
    class Program
    {
        static void Main(string[] args)
        {
            // 创建一个IP地址和端口号
            IPAddress ip = IPAddress.Parse("127.0.0.1");
            int port = 8888;

            // 创建一个Socket对象
            Socket serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            // 绑定Socket对象到IP地址和端口号上
            serverSocket.Bind(new IPEndPoint(ip, port));

            // 开始监听客户端连接请求
            serverSocket.Listen(10);

            Console.WriteLine("等待客户端连接...");

            // 接受客户端连接请求
            Socket clientSocket = serverSocket.Accept();

            Console.WriteLine("客户端连接成功！");

            // 向客户端发送消息
            byte[] buffer = Encoding.UTF8.GetBytes("欢迎连接到服务器！");
            clientSocket.Send(buffer);

            // 接收客户端发送的消息
            buffer = new byte[1024];
            int length = clientSocket.Receive(buffer);
            string message = Encoding.UTF8.GetString(buffer, 0, length);
            Console.WriteLine("接收到客户端消息：" + message);

            // 关闭Socket连接
            clientSocket.Shutdown(SocketShutdown.Both);
            clientSocket.Close();
            serverSocket.Close();

            Console.ReadLine();
        }
    }
}

客户端代码：

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

namespace SocketClient
{
    class Program
    {
        static void Main(string[] args)
        {
            // 创建一个IP地址和端口号
            IPAddress ip = IPAddress.Parse("127.0.0.1");
            int port = 8888;

            // 创建一个Socket对象
            Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            // 连接到服务器
            clientSocket.Connect(new IPEndPoint(ip, port));

            // 接收服务器发送的消息
            byte[] buffer = new byte[1024];
            int length = clientSocket.Receive(buffer);
            string message = Encoding.UTF8.GetString(buffer, 0, length);
            Console.WriteLine("接收到服务器消息：" + message);

            // 向服务器发送消息
            message = "你好，服务器！";
            buffer = Encoding.UTF8.GetBytes(message);
            clientSocket.Send(buffer);

            // 关闭Socket连接
            clientSocket.Shutdown(SocketShutdown.Both);
            clientSocket.Close();

            Console.ReadLine();
        }
    }
}
