访问来自 WPF 的 Windows 通知

Access to Windows notification from WPF

如何从 WPF 获取 Windows 通知?

我试过这种方法。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");
        }
    }

解决方法: 将 WPF 个项目添加到 Windows Application Packaging Project
