c# - 如何使用套接字编程获取客户端IP

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

class Program
{
    static void Main(string[] args)
    {
        // 创建一个TCP套接字
        Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

        // 绑定套接字到本地IP地址和端口
        IPEndPoint localEndPoint = new IPEndPoint(IPAddress.Any, 12345);
        socket.Bind(localEndPoint);

        // 开始监听套接字
        socket.Listen(10);

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

        // 接受客户端连接
        Socket clientSocket = socket.Accept();

        // 获取客户端IP地址
        IPEndPoint clientEndPoint = (IPEndPoint)clientSocket.RemoteEndPoint;
        IPAddress clientIP = clientEndPoint.Address;

        Console.WriteLine("客户端IP地址：" + clientIP.ToString());

        // 关闭套接字
        clientSocket.Close();
        socket.Close();
    }
}
