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-_-）
