UdpClient.BeginReceive

在用C#开发UDP数据的时候，UdpClient有一个方法是UdpClient.BeginReceive，用来从远程主机异步接收数据报。

 1             UdpClient client = obj as UdpClient;
 2             IPEndPoint endpoint = new IPEndPoint(IPAddress.Any, 0);
 3             while (true)
 4             {
 5                 client.BeginReceive(
 6                     delegate (IAsyncResult result)
 7                     {
 8                         
 9                         byte[] receiveBytes = result.AsyncState as byte[];
10                         Console.WriteLine(BitConverter.ToString(receiveBytes));//委托接收消息
11                     }, 
12                     client.Receive(ref endpoint)
13                     );
14                 Thread.Sleep(1000);
15             }
