接收UDP广播(C#)的答案

我正在尝试发送udp广播,并在c#中收到答案.虽然发送广播完美,但我没有收到任何c#的答案.但是当我看看wireshark时,我可以看到已经发送了一个答案：

>从192.168.0.141发送到192.168.0.255
>从192.168.0.105发送到255.255.255.255(这将是答案)

Wireshark日志：

1   0.000000    192.168.0.141   192.168.0.255   UDP Source port: 55487  Destination port: 17784
2   0.000851    192.168.0.105   255.255.255.255 UDP Source port: 17784  Destination port: 55487

那是我的c#代码：

private static byte[] SendBuffer = new byte[] { 1,2,3 };

    public static void SendAndReceivebroadcast( byte[] data,IPEndPoint broadcastEndpoint )
    {

        using( Socket broadcastSocket = new Socket( AddressFamily.InterNetwork,SocketType.Dgram,ProtocolType.Udp ) )
        {
            broadcastSocket.SetSocketoption( SocketoptionLevel.socket,SocketoptionName.broadcast,1 );
            broadcastSocket.SendTo( data,broadcastEndpoint );
            receivePort = broadcastSocket.LocalEndPoint.ToString().Split( ':' )[1];
            Console.WriteLine( "Sent {0} from Port {1}",CollectionsHelper.ItemsToString( data,"{0:X2}" ),broadcastSocket.LocalEndPoint.ToString() );
            broadcastSocket.Close();
        }

        using( Socket receiveSocket = new Socket( AddressFamily.InterNetwork,ProtocolType.Udp ) )
        {
            IPEndPoint broadcastAddress = new IPEndPoint( IPAddress.Any,Convert.ToInt32( receivePort ) );
            UdpClient udpClient = new UdpClient();
            udpClient.Client.SetSocketoption( SocketoptionLevel.socket,SocketoptionName.ReuseAddress,true );
            udpClient.Client.Bind( broadcastAddress );
            IPEndPoint remoteIP = new IPEndPoint( IPAddress.Any,Convert.ToInt32( receivePort ) );
            byte[] answer = udpClient.Receive( ref remoteIP );
        }
    }

调用udpClient.Receive时程序停止.任何人都可以帮助我PLZ？
