如何在循环中使用UdpClient.BeginReceive

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

class Program
{
    static UdpClient udpClient;

    static void Main(string[] args)
    {
        udpClient = new UdpClient(1234); // 创建UdpClient对象，监听指定端口

        StartReceive(); // 开始接收数据

        Console.WriteLine("Press any key to exit.");
        Console.ReadKey();

        udpClient.Close(); // 关闭UdpClient对象
    }

    static void StartReceive()
    {
        udpClient.BeginReceive(ReceiveCallback, null); // 启动异步接收操作
    }

    static void ReceiveCallback(IAsyncResult ar)
    {
        IPEndPoint remoteEP = new IPEndPoint(IPAddress.Any, 0);
        byte[] receivedBytes = udpClient.EndReceive(ar, ref remoteEP); // 获取接收到的数据

        string receivedData = Encoding.UTF8.GetString(receivedBytes); // 将接收到的数据转换为字符串

        Console.WriteLine("Received data: " + receivedData);

        StartReceive(); // 继续接收数据
    }
}
