Question

我一直在MSDN http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh487166(v=vs.105).aspx上引用一个示例，它允许我确定网络更改和网络属性，例如网络名称，状态等。但是如何在网络更新之前获取相同的信息已经发生了？例如，当我的应用加载时，没有检测到网络更改，因此信息当前为空。我可以在页面导航到？

时强制触发NetworkAvailabilityChanged事件

// Subscribe to the NetworkAvailabilityChanged event
DeviceNetworkInformation.NetworkAvailabilityChanged += new EventHandler<NetworkNotificationEventArgs>(ChangeDetected);

...


// In this callback, we examine the change that was detected. In this example, we are 
// creating a simple information string and adding that to the event list on the UI. 
// In a real application, this is where you might adjust your communication connection 
// in order to take advantage of a network availability change. 
 void ChangeDetected(object sender, NetworkNotificationEventArgs e)
{
string change = string.Empty;
switch (e.NotificationType)
{
    case NetworkNotificationType.InterfaceConnected:
        change = "Connected to ";
        break;
    case NetworkNotificationType.InterfaceDisconnected:
        change = "Disconnected from ";
        break;
    case NetworkNotificationType.CharacteristicUpdate:
        change = "Characteristics changed for ";
        break;
    default:
        change = "Unknown change with ";
        break;
}

string changeInformation = String.Format(" {0} {1} {2} ({3})",
            DateTime.Now.ToString(), change, e.NetworkInterface.InterfaceName,
            e.NetworkInterface.InterfaceType.ToString());

// We are making UI updates, so make sure these happen on the UI thread.
Dispatcher.BeginInvoke(() =>
{
    Changes.Add(changeInformation);
    UpdateNetworkStatus();
    UpdateNetworkInterfaces();

});

}

您可以通过DeviceNetworkInformation类获取网络信息。

您可以通过添加此

来获取此DeviceNetworkInformation

“使用Microsoft.Phone.Net.NetworkInformation;”

这里是Microsoft的link获取DeviceNetworkInformation。

希望这会有所帮助。（如果我错了，或者如果它不起作用，请纠正我）

谢谢。
