如何确定我是否连接到WiFi或在Windows Phone的8.1（通用应用程序）移动网络？ [英] How can I determine whether I am connected to WiFi or a mobile network in Windows Phone 8.1 (Universal app)?

问题描述

我与（是Windows 8.1和Windows Phone 8.1，而不是Silverlight的共享后端）一个Windows应用程序的通用工作。该应用程序连接的Azure与移动服务到Azure。在该应用的设置，我想有同步只能通过WiFi网络出现的选项。

我怎么能确定手机连接到WiFi或移动网络？虽然从我的研究，我已经找到了与旧版本的Windows Phone和Silverlight来做到这一点，看来我只能确定设备是否连接到Windows通用应用互联网。

我相信你能确定从的 ConnectionProfile 使用的东西类似：

 使用Windows.Networking.Connectivity; 
 
 VAR connectionProfile = NetworkInformation.GetInternetConnectionProfile（）; 
 // connectionProfile可以为空（例如飞行模式）
如果（connectionProfile = NULL&放大器;！&安培; connectionProfile.IsWlanConnectionProfile）{
 //做点什么通过WiFi; 
} 
  

也有 IsWwanConnectionProfile 属性，它用于确定是否连接是通过一个移动连接（3G等）。

I am working with a Windows Universal app (shared backend between Windows 8.1 and Windows Phone 8.1, not Silverlight). The app connects to Azure with Azure Mobile Services. In the settings for the app I would like to have an option for synchronisation to only occur over a WiFi network.

How can I determine if the phone is connected to WiFi or a mobile network? Although from my research I have found ways to do this with older versions of Windows Phone and with Silverlight, it seems I can only determine if the device is connected to the internet in a Windows Universal app.

解决方案

I believe you can determine this information from the ConnectionProfile using something akin to:

using Windows.Networking.Connectivity;

var connectionProfile = NetworkInformation.GetInternetConnectionProfile();
// connectionProfile can be null (e.g. airplane mode)
if (connectionProfile != null && connectionProfile.IsWlanConnectionProfile) {
    // do something over WiFi;
}

There is also the IsWwanConnectionProfile property, which is used to determine if the connection is via a 'mobile' connection (3g, etc).
