推荐答案

您可以简单地尝试:

 if (NetworkInformation.GetInternetConnectionProfile() == null)
        {
            //no connection
        }

正如您在此 msdn 文档中所见:NetworkInformation.GetInternetConnectionProfile

As you can see in this msdn documentation:NetworkInformation.GetInternetConnectionProfile

如果没有具有合适连接的连接配置文件"，它将返回null

It will return null if there is "no connection profile with a suitable connection"

您还可以通过以下方式明确检查互联网访问"级别:NetworkInformation.GetInternetConnectionProfile().GetNetworkConnectivityLevel() == NetworkConnectivityLevel.InternetAccess

You can also check explicity the "Internet Access" level with this: NetworkInformation.GetInternetConnectionProfile().GetNetworkConnectivityLevel() == NetworkConnectivityLevel.InternetAccess

我认为这也适用于通用应用程序.

I Think this will work also in universal app.
