WinRT 中检查 WiFi 是否可用

 public static bool IsWifiConnected()
 {
     bool isWifiConnected = false;
     ConnectionProfile currentConnectionForInternet = NetworkInformation.GetInternetConnectionProfile();
     if(currentConnectionForInternet == null)
     {
         return false;
     }
     if(currentConnectionForInternet.IsWlanConnectionProfile)
     {
         if(currentConnectionForInternet.GetNetworkConnectivityLevel() == NetworkConnectivityLevel.InternetAccess)
         {
             return true;
         }
     }
     return false;
 }

Windows 8.1 和 Windows Phone 8.1 Runtime 检测 WiFi 是否可用使用以上方法。（感觉比WP8 silverlight 麻烦-_-）
