Windows IoT核心版将数据发送到远程服务器52.139.250.253成本网络

Question

我编写了一个程序来收集数据，并通过4g路由器将其传输到我的服务器。但是我发现Windows IoT核心从服务器52.139.250.253发送和接收数据，它花费大量网络，我进行了大量搜索，找不到有用的信息，不知道会发生什么，如何禁用它？

这是我的代码，非常简单

 public class TcpConnection:IConnection
{
    Socket _TcpClient;
    IPEndPoint _ServerIp;
    string _IpOrUrl = string.Empty;
    int _PortNO;
    Boolean IsRecieve { get; set; } = false;
    private event Action<byte[]> DataRecieved = null;
    private int _TcpTimeout { set; get; } = 5000;
    public TcpConnection(string ipOrUrl, int portNO)
    {
        _ServerIp = new IPEndPoint(IPAddress.Parse(ipOrUrl), portNO);
        _TcpClient = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        _TcpClient.SendTimeout = this._TcpTimeout;//等待测试
        this._IpOrUrl = ipOrUrl;
        this._PortNO = portNO;
        this.ConnectAsync();
    }

    public async void ConnectAsync()
    {
        try
        {
            if (!_TcpClient.Connected)
            {
                await this._TcpClient.ConnectAsync(_ServerIp);
                AsynRecive();
            }
        }
        catch { }
    }
    private void AsynRecive()
    {
        byte[] data = new byte[2048];
        _TcpClient.BeginReceive(data, 0, data.Length, SocketFlags.None, asyncResult =>
        {
            try
            {
                int length = this._TcpClient.EndReceive(asyncResult);
                if (length > 0)
                {
                    byte[] bytesBack = data.Take(length).ToArray();
                    try

                    {
                        LogHelper.Log(Ex.Message.ToString(), LogLevel.Debug);
                    }
                }
                AsynRecive();
            }
            catch (Exception)
            {
            }
        }, null);
    }
    public Boolean Send(byte[] data)
    {

            }
        return true;
        }

    }


    public void Close()
    {

    public void Connect()

您是否在初始化连接之前注意到转储中的DNS查找。看一下这是否用于将域解析为该IP地址。 如果确实如此，则似乎与WNS（Windows推送通知服务）有关：https://msdn.microsoft.com/de-de/windows/desktop/mt187203。
