通过 Windows.ApplicationModel.Appointments 命名空间，可以在用户的日历应用中创建和管理约会。 在这里，我们将演示如何创建约会，将其添加到日历应用，将其替换在日历应用中，并将其从日历应用中删除。 我们还将展示如何显示日历应用的时间区间并创建一个预约重复对象。
创建约会并向其应用数据
创建 Windows.ApplicationModel.Appointments.Appointment 对象并将其分配给变量。 然后，将用户通过UI提供的约会属性应用于 约会。

}
}
将约会添加到用户的日历
创建 Windows.ApplicationModel.Appointments.Appointment 对象并将其分配给变量。 然后，调用 AppointmentManager.ShowAddAppointmentAsync（Appointment，Rect，Placement） 方法来显示默认约会提供程序的添加约会 UI，以便用户添加约会。 如果用户单击了 添加，示例将输出由 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.";
}
}
注释 对于 Windows Phone 应用商店应用，ShowAddAppointment 的作用，就像 ShowEditNewAppointment 一样，用于添加约会的对话框是可编辑的。
替换掉用户日历中的约会
创建 Windows.ApplicationModel.Appointments.Appointment 对象并将其分配给变量。 然后，调用相应的 AppointmentManager.ShowReplaceAppointmentAsync 方法，以便显示默认的日程安排提供程序的替换约会用户界面，使用户可以更换一个约会。 用户还提供要替换的约会标识符。 此标识符是从 AppointmentManager.ShowAddAppointmentAsync返回的。 如果用户单击 替换，示例将打印出已更新的预约标识符。
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，以显示默认的约会提供商的删除约会用户界面，使用户可以删除约会。 用户还提供要删除的约会标识符。 此标识符是从 AppointmentManager.ShowAddAppointmentAsync返回的。 如果用户单击了 删除，示例将打印信息，显示它删除了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";
}
}
}
显示预约服务提供者的时间跨度
调用 AppointmentManager.ShowTimeFrameAsync 方法，以便在用户单击 显示时显示默认约会提供程序的主要 UI 的特定时间跨度。 示例显示默认的约会提供程序出现在屏幕上。
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.";
}
创建会议重复对象，并将数据应用于该对象
创建 Windows.ApplicationModel.Appointments.AppointmentRecurrence 对象并将其分配给变量。 然后，对 AppointmentRecurrence 应用用户通过 UI 提供的重复属性。
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 的工作方式与 ShowAddAppointmentAsync 相同，只是添加约会的对话框是可编辑的，以便用户可以在保存约会数据之前修改约会数据。
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 使系统显示指定约会的详细信息。 实现应用日历的应用可以选择激活，以显示其拥有的日历中约会的详细信息。 否则，系统将显示约会详细信息。 提供了一个接受开始日期参数的重载函数，以显示一个定期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);
}
}
