Windows 10 UWP - C＃：如何检查网络类型（EDGE/3G/LTE），不仅是蜂窝与WLAN？

Question

我该如何检查目前使用哪种类型的蜂窝连接（EDGE/3G/LTE）？我只知道如何检查设备是否在蜂窝连接或WLAN上，但我需要特定类型的蜂窝连接。谢谢！

NetworkInformation应该可用于Windows 10（https://msdn.microsoft.com/en-us/library/windows.networking.connectivity.networkinformation.getinternetconnectionprofile.aspx?cs-save-lang=1&cs-lang=csharp#code-snippet-2）。

您必须调整此代码为您的需求：

/// <summary> 
    /// ("Connection Type", `0`-`3`): `0` - cellular, `1` - wifi/ethernet, `2` - inne; 
    /// </summary> 
    /// <returns></returns> 
    public byte GetConnectionGeneration() 
    { 
     try 
     { 
      ConnectionProfile profile = NetworkInformation.GetInternetConnectionProfile(); 
      if (profile.IsWwanConnectionProfile) 
      { 
       WwanDataClass connectionClass = profile.WwanConnectionProfileDetails.GetCurrentDataClass(); 
       switch (connectionClass) 
       { 
        //2G-equivalent 
        case WwanDataClass.Edge: 
        case WwanDataClass.Gprs: 
        //3G-equivalent 
        case WwanDataClass.Cdma1xEvdo: 
        case WwanDataClass.Cdma1xEvdoRevA: 
        case WwanDataClass.Cdma1xEvdoRevB: 
        case WwanDataClass.Cdma1xEvdv: 
        case WwanDataClass.Cdma1xRtt: 
        case WwanDataClass.Cdma3xRtt: 
        case WwanDataClass.CdmaUmb: 
        case WwanDataClass.Umts: 
        case WwanDataClass.Hsdpa: 
        case WwanDataClass.Hsupa: 
        //4G-equivalent 
        case WwanDataClass.LteAdvanced: 
         return 0; 

        //not connected 
        case WwanDataClass.None: 
         return 2; 

        //unknown 
        case WwanDataClass.Custom: 
        default: 
         return 2; 
       } 
      } 
      else if (profile.IsWlanConnectionProfile) 
      { 
       return 1; 
      } 
      return 2; 
     } 
     catch (Exception) 
     { 
      return 2; //as default 
     } 

    }
