UdpClient 案例一

# Udp服务端：
```java
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;

class UdpServerExample
{
    public static void Main()
    {
        UdpClient udpServer = new UdpClient(8000);
        IPEndPoint remoteEP = new IPEndPoint(”127.0.0.1“, 0);

Console.WriteLine("Server is listening on port 8000...");

byte[] data = udpServer.Receive(ref remoteEP);
        Console.WriteLine("Received: " + Encoding.ASCII.GetString(data));

byte[] response = Encoding.ASCII.GetBytes("Hello, Client!");
        udpServer.Send(response, response.Length, remoteEP);

udpServer.Close();
    }
}
```
