无法调试 UDPclient 客户端接收

Question

我想使用以下端口从以下 IP 地址接收数据包。问题出在"client.Receive(ref localEp);"这一行代码没有运行也无法调试

UdpClient client = new UdpClient();

IPEndPoint localEp = new IPEndPoint(IPAddress.Any, 17000);
client.Client.Bind(localEp);

IPAddress multicastaddress = IPAddress.Parse("224.0.0.10");
client.JoinMulticastGroup(multicastaddress);

while (true)
{
     Byte[] data = client.Receive(ref localEp);
     string strData = Encoding.UTF8.GetString(data);
     Console.WriteLine(strData);
}

我也得到这个异常 ScopeId = 'localEp.Address.ScopeId' 在 IPEndPoint localEp 中抛出了类型 'System.Net.Sockets.SocketException' 的异常。请帮助更正我的代码

UPDATE 解决办法是，在我的机器上安装了HYPER-V虚拟机设置，限制了这个udp数据的接收。我只是禁用它并开始接收数据。老实说，我不知道它的行为。

首先尝试msdn方式从本地主机接收来自任何源的数据，然后从其他主机名接收数据：

https://msdn.microsoft.com/en-us/library/system.net.sockets.udpclient(v=vs.110).aspx

// This constructor arbitrarily assigns the local port number.
    UdpClient udpClient = new UdpClient(17000);

    udpClient.Connect("127.0.0.1", 17000);

    // Sends a message to the host to which you have connected.
    Byte[] sendBytes = Encoding.ASCII.GetBytes("Is anybody there?");

    udpClient.Send(sendBytes, sendBytes.Length);

    //// Sends a message to a different host using optional hostname and port parameters.
    //UdpClient udpClientB = new UdpClient();
    //udpClientB.Send(sendBytes, sendBytes.Length, "AlternateHostMachineName", 17000);

    //IPEndPoint object will allow us to read datagrams sent from any source.
    IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Any, 0);

    // Blocks until a message returns on this socket from a remote host.
    Byte[] receiveBytes = udpClient.Receive(ref RemoteIpEndPoint);
    string returnData = Encoding.ASCII.GetString(receiveBytes);
