C＃EWS 2.0ライブラリを使用していくつかのイベントを一覧表示しようとしています。EWS - 出席者の読み込み中に予定表の予定を一覧表示できない
は次のコードを使用している次のよう
public IEnumerable<AppEvent> ListEvents(CalendarFolder folder, DateTime? startDate, DateTime? endDate)
{
var items = new List<AppEvent>();
var now = DateTime.Now;
if (startDate == null) startDate = DateTime.Now;
if (endDate == null) endDate = now.AddDays(14);
FindItemsResults<Appointment> findResults = null;
ServiceResponseCollection<GetItemResponse> appointments = null;
CalendarView view = null;
view = new CalendarView((DateTime)startDate, (DateTime)endDate);
findResults = folder.FindAppointments(view);
if (findResults.Items.Count() == 0) return items;
appointments = Service.BindToItems(findResults.Select(item => item.Id), AppointmentPropertySet);
foreach (GetItemResponse item in appointments)
{
var appointment = item.Item as Appointment;
try
{
if (appointment.IsCancelled) continue;
}
catch (System.NullReferenceException)
{
continue;
}
var evt = AppEvent.FromEWSAppointment(appointment);
items.Add(evt);
}
return items;
}
そしてAppointmentPropertySetがある：私たちはイベントのいずれかの次のエラーを取得している
protected PropertySet AppointmentPropertySet = new PropertySet(
AppointmentSchema.Subject,
AppointmentSchema.Start,
AppointmentSchema.End,
AppointmentSchema.IsAllDayEvent,
AppointmentSchema.IsMeeting,
AppointmentSchema.IsRecurring,
AppointmentSchema.IsCancelled,
AppointmentSchema.IsDraft,
AppointmentSchema.Location,
AppointmentSchema.Resources,
AppointmentSchema.RequiredAttendees,
AppointmentSchema.OptionalAttendees,
AppointmentSchema.LegacyFreeBusyStatus,
AppointmentSchema.Organizer,
AppointmentSchema.Body,
AppointmentSchema.Sensitivity,
AppointmentSchema.AppointmentReplyTime,
AppointmentSchema.AppointmentSequenceNumber,
AppointmentSchema.AppointmentState,
AppointmentSchema.AppointmentType,
AppointmentSchema.ConferenceType,
AppointmentSchema.DateTimeCreated,
AppointmentSchema.Duration,
AppointmentSchema.EndTimeZone,
AppointmentSchema.HasAttachments,
AppointmentSchema.ICalDateTimeStamp,
AppointmentSchema.ICalRecurrenceId,
AppointmentSchema.ICalUid,
AppointmentSchema.Id,
AppointmentSchema.Importance,
AppointmentSchema.IsOnlineMeeting,
AppointmentSchema.IsReminderSet,
AppointmentSchema.IsResponseRequested,
AppointmentSchema.IsUnmodified,
AppointmentSchema.LastModifiedTime,
AppointmentSchema.LegacyFreeBusyStatus,
AppointmentSchema.MeetingRequestWasSent,
AppointmentSchema.MyResponseType,
AppointmentSchema.MeetingWorkspaceUrl,
AppointmentSchema.NetShowUrl,
AppointmentSchema.OriginalStart,
AppointmentSchema.ParentFolderId,
AppointmentSchema.Recurrence,
AppointmentSchema.ReminderDueBy,
AppointmentSchema.ReminderMinutesBeforeStart,
AppointmentSchema.StartTimeZone,
AppointmentSchema.WebClientEditFormQueryString,
AppointmentSchema.WebClientReadFormQueryString
);
。 RequiredAttendeesとOptionalAttendeesをAppointmentPropertySetから削除すると、正常に機能します（ただし、出席者は返されません）。
このエラーを回避するにはどうすればよいですか、またはこのイベントをスキップして少なくともビューが壊れていない予定を返すようにするにはどうすればよいですか？例外スタックトレースから判断
