我使用此代码段没有问题:
public static bool IsInternet()
{
ConnectionProfile connections = NetworkInformation.GetInternetConnectionProfile();
bool internet = connections != null && connections.GetNetworkConnectivityLevel() == NetworkConnectivityLevel.InternetAccess;
return internet;
}

我必须使用GetConnectionProfiles()和GetInternetConnectionProfile()才能使其在所有设备上运行。
class ConnectivityUtil
{
internal static bool HasInternetConnection()
{
var connections = NetworkInformation.GetConnectionProfiles().ToList();
connections.Add(NetworkInformation.GetInternetConnectionProfile());
foreach (var connection in connections)
{
if (connection == null)
continue;
if (connection.GetNetworkConnectivityLevel() == NetworkConnectivityLevel.InternetAccess)
return true;
}
return false;
}
}

对于Windows Phone以下代码可能很有用:
var networkInformation = NetworkInformation.GetConnectionProfiles();
if (networkInformation.Count == 0)
{
//no network connection
}
