使用交換Web服務獲取日歷項目所需的參與者？ C＃

Question

我正在嘗試獲得使用交換Web服務的會議所需的與會者。 有任何想法嗎？ 我想我需要使用CalendarItemType，但我不確定如何實現它。 到目前為止，這是我的代碼：

        foreach (var wrk in Workers)
        {
            TimeWindow timeWindow = new TimeWindow(startDate, endDate);
            AvailabilityData requestedData = AvailabilityData.FreeBusy;
            List<AttendeeInfo> attendees = new List<AttendeeInfo>();
            attendees.Add(new AttendeeInfo(wrk.EmailAddress));
            GetUserAvailabilityResults ares = service.GetUserAvailability(attendees, timeWindow, requestedData);
            foreach (AttendeeAvailability av in ares.AttendeesAvailability)
            {
                foreach (CalendarEvent ev in av.CalendarEvents)
                {
                    //get info from each calendarevent
                    //Possibly use CalendarItemType here?
                 }
             }
         }

工人是我用類名單和相應的電子郵件地址列出的類。

您可以使用Appointment.Bind綁定到約會來檢索所需的與會者：

foreach (CalendarEvent ev in av.CalendarEvents)
{
    var appointment = Appointment.Bind(service, new ItemId(ev.Details.StoreId));
    foreach (var requiredAttendee in appointment.RequiredAttendees)
    {
        Console.WriteLine(requiredAttendee.Address);
    }
}

您可能必須在調用Appointment.Bind （我不確定這一點）之前將CalendarEvent.Details.StoreId轉換為其他格式，因此如果上述代碼不起作用，您可以嘗試添加對ExchangeService.ConvertId的調用：

foreach (CalendarEvent ev in av.CalendarEvents)
{
    var convertedId = (AlternateId) service.ConvertId(new AlternateId(IdFormat.HexEntryId, ev.Details.StoreId, "someemail@domain.com"), IdFormat.EwsId);

    var appointment = Appointment.Bind(service, new ItemId(convertedId.UniqueId));
    foreach (var requiredAttendee in appointment.RequiredAttendees)
    {
        Console.WriteLine(requiredAttendee.Address);
    }
}
