无法调试UDP客户端接收

首先尝试使用msdn方式从localhost的任何源接收数据,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);
