Question

我在尝试获取作为约会所需参加者的房间的ResponseType时遇到问题。我可以确认我的Exchange 2010 sp2 ru4服务器即时批准或拒绝会议，但是当我以编程方式查找与ExchangeManaged api的约会时，所讨论的所需与会者始终返回ResponseType的“未知”值。

这是我的代码......

 public bool IsAppointmentVerifiedWithResource(Patron userSessionObj, Reservation reservation)
    {
        var emailConfig = new DataStoreManager.ConfigurationManager();
        var serviceBinding = emailConfig.GetConfiguration(Configuration.GetConfigurationName(Resource_ConfigurationConstants.ExchangeServiceBinding));

        // Create the binding.
        var service = new ExchangeService(ExchangeVersion.Exchange2010_SP2)
        {
            UseDefaultCredentials = true,
            Url = new Uri(serviceBinding)
        };

        // Set the calendar view to use
        var view = new CalendarView(reservation.Start, reservation.End);

        // Get the target folder ID using the email address
        var folder = new FolderId(WellKnownFolderName.Calendar, new Mailbox(reservation.EmailAddress));

        view.PropertySet = new PropertySet(BasePropertySet.FirstClassProperties);

        if (CheckForApptCount(service, folder, view))
        {
            var response = service.FindAppointments(folder, view);

            service.LoadPropertiesForItems(from Item item in response select item, BasePropertySet.FirstClassProperties);

            foreach (Appointment apt in response.Items)
            {
                foreach(Attendee at in apt.RequiredAttendees)
                {
                    //room mailbox matches required attendee
                    if(at.Address == reservation.EmailAddress)
                    {
                        ******at.ResponseType always = Unknown******
                        if(at.ResponseType == MeetingResponseType.Accept)
                        {
                            return true;
                        }
                    }
                }
            }

        }

        return false;

    }

有关如何获取和加载ResponseType属性的任何想法？

谢谢，克里斯

            public static List<Appointment> GetStandardCalendarItems(ExchangeService service, DateTime dtStart, DateTime dtEnd)
            {
                // Instantiate a collection to hold occurrences and exception calendar items.
                List<Appointment> foundAppointments = new List<Appointment>();

                // Initialize values for the start and end times, and the number of appointments to retrieve.
                DateTime startDate = dtStart.AddDays(-1);
                DateTime endDate = startDate.AddDays(30);

                //// Create a calendar view to search the calendar folder and specify the properties to return.
                CalendarView calView = new CalendarView(startDate, endDate)
                {
                    PropertySet = new PropertySet(BasePropertySet.FirstClassProperties)

                FindItemsResults<Appointment> findResults = service.FindAppointments(WellKnownFolderName.Calendar, calView);

                // Add all calendar items in your view that are occurrences or exceptions to your collection.
                foreach (Appointment appt in findResults.Items)
                {


                    foundAppointments.Add(appt);

                }

                return foundAppointments;
            }

解决方案：与会者的ResponseType始终为null，因为我正在为与会者的邮箱执行“findappointments”，然后尝试获取此与会者的ResponseType。获取参加者的ResponseType的正确方法是为组织者的邮箱运行“findappointments”。找到约会后，枚举与会者并且响应类型将可用。
