微软希望你使用 DeviceNetworkInformation.IsNetworkAvailable

NetworkInterface是在System.Net其中如DeviceNetworkInformation在Microsoft.Phone.Net.NetworkInformation.

该DeviceNetworkInformation.IsNetworkAvailable会映射到NetworkInterface.GetIsNetworkAvailable()内部,但你应该总是使用DeviceNetworkInformation.IsNetworkAvailable,因为它为手机制造(和有一个更简洁的API).

正如Matthieu所指出的那样,DeviceNetworkInformation.IsNetworkAvailable在7.1(Mango)中显然是新的.
