class TcpListenerExample
{
    static void Main(string[] args)
    {
        // 设置监听的IP地址和端口号
        IPAddress ipAddress = IPAddress.Parse("127.0.0.1");
        int port = 8080;

        // 创建一个TcpListener实例
        TcpListener listener = new TcpListener(ipAddress, port);

        // 开始监听
        listener.Start();
        Console.WriteLine($"TCP listener started on {ipAddress}:{port}");

        // 等待客户端连接
        while (true)
        {
            // 接受客户端连接
            TcpClient client = listener.AcceptTcpClient();
            Console.WriteLine($"Client connected: {client.Client.RemoteEndPoint}");

            // 处理客户端请求
            Task.Run(() => HandleClient(client));
        }
    }

    static async Task HandleClient(TcpClient client)
    {
        // 读取客户端发送的数据
        NetworkStream stream = client.GetStream();
        byte[] buffer = new byte[1024];
        int bytesRead = await stream.ReadAsync(buffer, 0, buffer.Length);
        string request = Encoding.UTF8.GetString(buffer, 0, bytesRead);
        Console.WriteLine($"Received request: {request}");

        // 响应客户端
        string response = "Hello from server!";
        byte[] responseBytes = Encoding.UTF8.GetBytes(response);
        await stream.WriteAsync(responseBytes, 0, responseBytes.Length);
        Console.WriteLine($"Sent response: {response}");

        // 关闭客户端连接
        client.Close();
    }
