管理约会
通过 Windows.ApplicationModel.Appointments 命名空间，你可以在用户的日历应用中创建和管理约会。 我们将在此处向你介绍如何创建约会、将其添加到日历应用、在日历应用中替换它以及从日历应用中删除它。 我们还将介绍如何显示日历应用的时间跨度以及创建一个约会循环对象。
创建一个约会并向其应用数据
创建一个 Windows.ApplicationModel.Appointments.Appointment 对象并将其分配给某个变量。 然后，应用到由用户通过 UI 提供的 Appointment 约会属性。
private void Create-Click(object sender, RoutedEventArgs e)
{
bool isAppointmentValid = true;
var appointment = new Windows.ApplicationModel.Appointments.Appointment();
// StartTime
var date = StartTimeDatePicker.Date;
var time = StartTimeTimePicker.Time;
var timeZoneOffset = TimeZoneInfo.Local.GetUtcOffset(DateTime.Now);
var startTime = new DateTimeOffset(date.Year, date.Month, date.Day, time.Hours, time.Minutes, 0, timeZoneOffset);
appointment.StartTime = startTime;
// Subject
appointment.Subject = SubjectTextBox.Text;

}
// Uri
if (UriTextBox.Text.Length > 0)
{
try
{
appointment.Uri = new System.Uri(UriTextBox.Text);
}
catch (Exception)
{
isAppointmentValid = false;
ResultTextBlock.Text = "The Uri provided is invalid.";
}
}
// Organizer
// Note: Organizer can only be set if there are no invitees added to this appointment.
if (OrganizerRadioButton.IsChecked.Value)
{
var organizer = new Windows.ApplicationModel.Appointments.AppointmentOrganizer();
// Organizer Display Name
organizer.DisplayName = OrganizerDisplayNameTextBox.Text;

// Invitees
// Note: If the size of the Invitees list is not zero, then an Organizer cannot be set.
if (InviteeRadioButton.IsChecked.Value)
{
var invitee = new Windows.ApplicationModel.Appointments.AppointmentInvitee();
// Invitee Display Name
invitee.DisplayName = InviteeDisplayNameTextBox.Text;
if (invitee.DisplayName.Length > 256)

appointment.Invitees.Add(invitee);
}
}
}
if (isAppointmentValid)
{
ResultTextBlock.Text = "The appointment was created successfully and is valid.";
}
}
向用户的日历添加约会
创建一个 Windows.ApplicationModel.Appointments.Appointment 对象并将其分配给某个变量。 然后，调用 AppointmentManager.ShowAddAppointmentAsync(Appointment, Rect, Placement) 方法来显示默认约会提供程序添加约会 UI，以使用户能够添加约会。 如果用户单击了“添加”，该示例将打印 ShowAddAppointmentAsync 返回的约会标识符。
private async void Add-Click(object sender, RoutedEventArgs e)
{
// Create an Appointment that should be added the user's appointments provider app.
var appointment = new Windows.ApplicationModel.Appointments.Appointment();
// Get the selection rect of the button pressed to add this appointment
var rect = GetElementRect(sender as FrameworkElement);
// ShowAddAppointmentAsync returns an appointment id if the appointment given was added to the user's calendar.
// This value should be stored in app data and roamed so that the appointment can be replaced or removed in the future.
// An empty string return value indicates that the user canceled the operation before the appointment was added.
String appointmentId = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowAddAppointmentAsync(
appointment, rect, Windows.UI.Popups.Placement.Default);
if (appointmentId != String.Empty)
{
ResultTextBlock.Text = "Appointment Id: " + appointmentId;
}
else
{
ResultTextBlock.Text = "Appointment not added.";
}
}
注意 对于 Windows Phone 应用商店应用，ShowAddAppointment 的功能与 ShowEditNewAppointment 相同，它们所显示的用于添加约会的对话框都可进行编辑。
在用户的日历中替换约会
创建一个 Windows.ApplicationModel.Appointments.Appointment 对象并将其分配给某个变量。 然后，调用合适的 AppointmentManager.ShowReplaceAppointmentAsync 方法来显示默认约会提供程序替换约会 UI，以使用户能够替换约会。 用户还可以提供他们想要替换的约会标识符。 此标识符已从 AppointmentManager.ShowAddAppointmentAsync 中返回。 如果用户单击了“替换”，该示例将指示它已更新该约会标识符。
private async void Replace-Click(object sender, RoutedEventArgs e)
{
// The appointment id argument for ReplaceAppointmentAsync is typically retrieved from AddAppointmentAsync and stored in app data.
String appointmentIdOfAppointmentToReplace = AppointmentIdTextBox.Text;
if (String.IsNullOrEmpty(appointmentIdOfAppointmentToReplace))
{
ResultTextBlock.Text = "The appointment id cannot be empty";
}
else
{
// The Appointment argument for ReplaceAppointmentAsync should contain all of the Appointment' s properties including those that may have changed.
var appointment = new Windows.ApplicationModel.Appointments.Appointment();
// Get the selection rect of the button pressed to replace this appointment
var rect = GetElementRect(sender as FrameworkElement);
// ReplaceAppointmentAsync returns an updated appointment id when the appointment was successfully replaced.
// The updated id may or may not be the same as the original one retrieved from AddAppointmentAsync.
// An optional instance start time can be provided to indicate that a specific instance on that date should be replaced
// in the case of a recurring appointment.
// If the appointment id returned is an empty string, that indicates that the appointment was not replaced.
String updatedAppointmentId;
if (InstanceStartDateCheckBox.IsChecked.Value)
{
// Replace a specific instance starting on the date provided.
var instanceStartDate = InstanceStartDateDatePicker.Date;
updatedAppointmentId = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowReplaceAppointmentAsync(
appointmentIdOfAppointmentToReplace, appointment, rect, Windows.UI.Popups.Placement.Default, instanceStartDate);
}
else
{
// Replace an appointment that occurs only once or in the case of a recurring appointment, replace the entire series.
updatedAppointmentId = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowReplaceAppointmentAsync(
appointmentIdOfAppointmentToReplace, appointment, rect, Windows.UI.Popups.Placement.Default);
}
if (updatedAppointmentId != String.Empty)
{
ResultTextBlock.Text = "Updated Appointment Id: " + updatedAppointmentId;
}
else
{
ResultTextBlock.Text = "Appointment not replaced.";
}
}
}
从用户的日历中删除约会
调用合适的 AppointmentManager.ShowRemoveAppointmentAsync 方法来显示默认约会提供程序删除约会 UI，以使用户能够删除约会。 用户还可以提供他们想要删除的约会标识符。 此标识符已从 AppointmentManager.ShowAddAppointmentAsync 中返回。 如果用户单击了“删除”，该示例将指示它已删除由该约会标识符指定的约会。
private async void Remove-Click(object sender, RoutedEventArgs e)
{
// The appointment id argument for ShowRemoveAppointmentAsync is typically retrieved from AddAppointmentAsync and stored in app data.
String appointmentId = AppointmentIdTextBox.Text;
// The appointment id cannot be null or empty.
if (String.IsNullOrEmpty(appointmentId))
{
ResultTextBlock.Text = "The appointment id cannot be empty";
}
else
{
// Get the selection rect of the button pressed to remove this appointment
var rect = GetElementRect(sender as FrameworkElement);
// ShowRemoveAppointmentAsync returns a boolean indicating whether or not the appointment related to the appointment id given was removed.
// An optional instance start time can be provided to indicate that a specific instance on that date should be removed
// in the case of a recurring appointment.
bool removed;
if (InstanceStartDateCheckBox.IsChecked.Value)
{
// Remove a specific instance starting on the date provided.
var instanceStartDate = InstanceStartDateDatePicker.Date;
removed = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowRemoveAppointmentAsync(
appointmentId, rect, Windows.UI.Popups.Placement.Default, instanceStartDate);
}
else
{
// Remove an appointment that occurs only once or in the case of a recurring appointment, replace the entire series.
removed = await Windows.ApplicationModel.Appointments.AppointmentManager.ShowRemoveAppointmentAsync(
appointmentId, rect, Windows.UI.Popups.Placement.Default);
}
if (removed)
{
ResultTextBlock.Text = "Appointment removed";
}
else
{
ResultTextBlock.Text = "Appointment not removed";
}
}
}
显示约会提供程序的时间跨度
如果用户单击了显示，则调用 AppointmentManager.ShowTimeFrameAsync 方法来为默认约会提供程序的主 UI 显示特定时间跨度。 该示例指示默认约会提供程序已显示在屏幕上。
private async void Show-Click(object sender, RoutedEventArgs e)
{
var dateToShow = new DateTimeOffset(2015, 6, 12, 18, 32, 0, 0, TimeSpan.FromHours(-8));
var duration = TimeSpan.FromHours(1);
await Windows.ApplicationModel.Appointments.AppointmentManager.ShowTimeFrameAsync(dateToShow, duration);
ResultTextBlock.Text = "The default appointments provider should have appeared on screen.";
}
创建一个约会循环对象并向其应用数据
创建一个 Windows.ApplicationModel.Appointments.AppointmentRecurrence 对象并将其分配给某个变量。 然后，应用到由用户通过 UI 提供的 AppointmentRecurrence 循环属性。
private void Create-Click(object sender, RoutedEventArgs e)
{
bool isRecurrenceValid = true;
var recurrence = new Windows.ApplicationModel.Appointments.AppointmentRecurrence();
// Unit
switch (UnitComboBox.SelectedIndex)
{
case 0:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Daily;
break;
case 1:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Weekly;
break;
case 2:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Monthly;
break;
case 3:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.MonthlyOnDay;
break;
case 4:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Yearly;
break;
case 5:
recurrence.Unit = Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.YearlyOnDay;
break;
}
// Occurrences
// Note: Occurrences and Until properties are mutually exclusive.
if (OccurrencesRadioButton.IsChecked.Value)
{
recurrence.Occurrences = (uint)OccurrencesSlider.Value;
}
// Until
// Note: Until and Occurrences properties are mutually exclusive.
if (UntilRadioButton.IsChecked.Value)
{
recurrence.Until = UntilDatePicker.Date;
}
// Interval
recurrence.Interval = (uint)IntervalSlider.Value;
// Week of the month
switch (WeekOfMonthComboBox.SelectedIndex)
{
case 0:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.First;
break;
case 1:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.Second;
break;
case 2:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.Third;
break;
case 3:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.Fourth;
break;
case 4:
recurrence.WeekOfMonth = Windows.ApplicationModel.Appointments.AppointmentWeekOfMonth.Last;
break;
}
// Days of the Week
// Note: For Weekly, MonthlyOnDay or YearlyOnDay recurrence unit values, at least one day must be specified.
if (SundayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Sunday; }
if (MondayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Monday; }
if (TuesdayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Tuesday; }
if (WednesdayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Wednesday; }
if (ThursdayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Thursday; }
if (FridayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Friday; }
if (SaturdayCheckBox.IsChecked.Value) { recurrence.DaysOfWeek |= Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.Saturday; }
if (((recurrence.Unit == Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.Weekly) ||
(recurrence.Unit == Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.MonthlyOnDay) ||
(recurrence.Unit == Windows.ApplicationModel.Appointments.AppointmentRecurrenceUnit.YearlyOnDay)) &&
(recurrence.DaysOfWeek == Windows.ApplicationModel.Appointments.AppointmentDaysOfWeek.None))
{
isRecurrenceValid = false;
ResultTextBlock.Text = "The recurrence specified is invalid. For Weekly, MonthlyOnDay or YearlyOnDay recurrence unit values, " +
"at least one day must be specified.";
}
// Month of the year
recurrence.Month = (uint)MonthSlider.Value;
// Day of the month
recurrence.Day = (uint)DaySlider.Value;
if (isRecurrenceValid)
{
ResultTextBlock.Text = "The recurrence specified was created successfully and is valid.";
}
}
添加新的可编辑约会
ShowEditNewAppointmentAsync 的工作原理与 ShowAddAppointmentAsync 类似，不同之处在于可编辑用于添加约会的对话框，以便用户可以先修改约会数据，然后再进行保存。
private async void AddAndEdit-Click(object sender, RoutedEventArgs e)
{
// Create an Appointment that should be added the user' s appointments provider app.
var appointment = new Windows.ApplicationModel.Appointments.Appointment();
appointment.StartTime = DateTime.Now + TimeSpan.FromDays(1);
appointment.Duration = TimeSpan.FromHours(1);
appointment.Location = "Meeting location";
appointment.Subject = "Meeting subject";
appointment.Details = "Meeting description";
appointment.Reminder = TimeSpan.FromMinutes(15); // Remind me 15 minutes prior
// ShowAddAppointmentAsync returns an appointment id if the appointment given was added to the user' s calendar.
// This value should be stored in app data and roamed so that the appointment can be replaced or removed in the future.
// An empty string return value indicates that the user canceled the operation before the appointment was added.
String appointmentId =
await Windows.ApplicationModel.Appointments.AppointmentManager.ShowEditNewAppointmentAsync(appointment);
if (appointmentId != String.Empty)
{
ResultTextBlock.Text = "Appointment Id: " + appointmentId;
}
else
{
ResultTextBlock.Text = "Appointment not added.";
}
}
显示约会详细信息
ShowAppointmentDetailsAsync 可使系统显示有关特定约会的详细信息。 可以选择激活实现应用日历的应用，以显示它在日历中包含的约会的详细信息。 否则，系统将显示该约会的详细信息。 将提供可接受开始日期参数的方法重载，以显示有关重复约会实例的详细信息。
private async void ShowAppointmentDetails-Click(object sender, RoutedEventArgs e)
{
if (instanceStartTime == null)
{
await Windows.ApplicationModel.Appointments.AppointmentManager.ShowAppointmentDetailsAsync(
currentAppointment.LocalId);
}
else
{
// Specify a start time to show an instance of a recurring appointment
await Windows.ApplicationModel.Appointments.AppointmentManager.ShowAppointmentDetailsAsync(
currentAppointment.LocalId, instanceStartTime);
}
}
