从WPF访问Windows通知

Question

如何从WPF访问Windows通知？

我试过这种方式。我获得了accessStatus许可。

但我得到了例外System.Exception: 'Element not found. (Exception from HRESULT: 0x80070490)

这是我的代码：

using Windows.UI.Notifications.Management;
***
public partial class NotificationWindow : Window
{
UserNotificationListener listener;
public NotificationWindow()
{
InitializeComponent();
SubscribeToNotif();
}
public async void SubscribeToNotif()
{    
listener = UserNotificationListener.Current;

UserNotificationListenerAccessStatus accessStatus = await listener.RequestAccessAsync();
if(accessStatus == UserNotificationListenerAccessStatus.Allowed)
listener.NotificationChanged += Listener_NotificationChanged;
}
private void Listener_NotificationChanged(UserNotificationListener sender, Windows.UI.Notifications.UserNotificationChangedEventArgs args)
{
Console.WriteLine("Got notif");
}
}
