UWP C# Windows IoT 创建约会

Question

我有一个较早的帖子UWP C# Windows 10 IoT Alarm Clock，我目前正在改用Appointment。 我有一个添加约会的对话框。当我在 rasp pi 上运行时，它似乎没有保存约会并触发它。 请指教。 我也希望能够在约会触发时触发外部输出引脚。

private async void Save_PrimaryButtonClick(ContentDialog sender, ContentDialogButtonClickEventArgs args)
    {
        var appointment = new Windows.ApplicationModel.Appointments.Appointment();
        var recurrence = new Windows.ApplicationModel.Appointments.AppointmentRecurrence();

        var scheduleTime = TimePicker.Time;
        var timeZoneOffset = TimeZoneInfo.Local.GetUtcOffset(DateTime.Now);
        var startTime = new DateTimeOffset(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, scheduleTime.Hours, scheduleTime.Minutes, 0, timeZoneOffset);
        appointment.StartTime = startTime;
        appointment.Subject = "Schedule Timer";

        appointment.Duration = TimeSpan.FromMinutes(5);

        if(dailyAlarm.IsOn == true)
        {
            recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Daily;
        } else
        {
            if (setMonday.IsChecked == true) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Monday; }
            if (setTuesday.IsChecked == true) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Tuesday; }
            if (setWednesday.IsChecked == true) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Wednesday; }
            if (setThursday.IsChecked == true) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Thursday; }
            if (setFriday.IsChecked == true) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Friday; }
            if (setSaturdayday.IsChecked == true) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Saturday; }
            if (setSunday.IsChecked == true) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Sunday; }
        }



        string appointmentId = await AppointmentManager.ShowAddAppointmentAsync(appointment, rect, Windows.UI.Popups.Placement.Default);

        }

不是您问题的真正答案，因为我无法解决这个问题，我的 Pi 在家，我在办公室。但是，我相信您可以创建与正在执行的操作非常相似的内容并将其用于您的应用程序。

这是一个示例类：

public delegate void AlarmReadyToRing(object sender, object alarm);
public class AppointmentViewer
{
    public event AlarmReadyToRing AlarmIsReady;
    public List<object> Appointments { get; private set; }

    private Timer _AlarmClock;

    public AppointmentViewer()
    {
        LoadAppointmentsFromStorage();
        _AlarmClock = new Timer(TriggerAlarms, null, 0, (int)TimeSpan.FromSeconds(1).TotalMilliseconds);
    }

    private void TriggerAlarms(object state)
    {

        if (DateTime.Now.Second == 59)
        {
            // Reset the timer so that it is checking every 60 seconds
            _AlarmClock.Change(0, (int)TimeSpan.FromSeconds(60).TotalMilliseconds);
        }

        // Find all alarms that should be going off now
        // FindAppointments(x=>x.StartTime == Datetime.Now)
        var readyAlarms = FindAppointments(x=> 1==1);
        foreach (var alarm in readyAlarms)
        {
            AlarmIsReady?.Invoke(this, alarm);
        }
    }

    public void SaveAppointment(object appt)
    {
        // Save appointment logic
        Appointments.Add(appt);
    }

    public void LoadAppointmentsFromStorage()
    {
        // Load appointments from local storage or other
        Appointments = new List<object>();
    }

    public List<object> FindAppointments(Func<object, bool> search)
    {
        var found = Appointments.Where(search);
        return found.ToList();
    }
}


public class SomeOtherClass
{
    private static AppointmentViewer ApptViewer { get; set; } = new AppointmentViewer();

    public SomeOtherClass()
    {
        // Register for event
        ApptViewer.AlarmIsReady += DoSomething;
    }

    private void DoSomething(object sender, object alarm)
    {
        // Here is the incoming alarm that needs to be going off
        // Apply logic for app to display alarm
    }
}
