c# - 如何从 Windows Phone 8.1 中的设备日历中删除约会

Question

当我尝试通过我的应用程序从设备日历中删除一个事件时，它显示错误

错误信息:

An exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.ni.dll but was not handled in user code

Additional information: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

请看下面我用于删除操作的代码

 AppointmentStore appointmentStore = await AppointmentManager.RequestStoreAsync(AppointmentStoreAccessType.AppCalendarsReadWrite);
         AppointmentCalendar sysCal = await appointmentStore.GetAppointmentCalendarAsync(dCalendarID);
          await sysCal.DeleteAppointmentAsync(dCalendarEventID);

任何人对此有任何想法请帮助我。谢谢

您是否有权使用日历？在应用程序 list 文件 WMAppManifest.xml 中查找 ID_CAP_APPOINTMENTS。
