排定的Toast通知UWP

Question

我想做一个定期的祝酒通知。

public sealed partial class MainPage : Page
{
    const string TOAST = @"
                        <toast>
                          <visual>
                            <binding template=""ToastTest"">
                              <text>Hello Toast</text>
                            </binding>
                          </visual>
                          <audio src =""ms-winsoundevent:Notification.Mail"" loop=""true""/>
                        </toast>";

    public MainPage()
    {
        this.InitializeComponent();
    }

    private void btnNotification_Click(object sender, RoutedEventArgs e)
    {
        var when = DateTime.Now.AddSeconds(6);
        var offset = new DateTimeOffset(when);

        Windows.Data.Xml.Dom.XmlDocument xml = new Windows.Data.Xml.Dom.XmlDocument();
        xml.LoadXml(TOAST);
        ScheduledToastNotification toast = new ScheduledToastNotification(xml, offset, TimeSpan.FromSeconds(5), 5);
        toast.Id = "IdTostone";
        toast.Tag = "NotificationOne";
        ToastNotificationManager.CreateToastNotifier().AddToSchedule(toast);
    }
}

错在哪里？

提前道谢！

Answer 1

ScheduledToastNotification构造函数的参数SnoozeInterval的值范围应为1分钟到1小时。

因此，只需将获得异常的代码行改为如下所示：

ScheduledToastNotification toast = new ScheduledToastNotification(xml, offset, TimeSpan.FromMinutes(1), 5);
