交换 EWS、日历 FindItems 与 FindAppointments？

Question

我按照本指南检索了通过 Outlook 在 Exchange 中召开的会议； https://msdn.microsoft.com/en-us/library/office/dn495614(v=exchg.150).aspx

一切正常，无一例外，但 return 没有任何结果。然后我尝试了 FindItems 而不是 FindAppointments，这 return 我的结果。为什么 FindAppointments 不 return 会议？

我正在 Outlook Online 中创建测试约会。通过单击“菜单”>“日历”>“新建”，我完成了事件的详细信息，然后在保存之前添加了与会者。这些是由 FindItems() 编辑的 return，但似乎没有属性来检索位置和参加者列表？如果数据是 returned，FindAppointments 会给我所需的属性。我之前在计算机上安装了 Outlook，在创建会议时特别提到 'Meeting' 这个词，这似乎是日历项目。我不确定有什么区别？

我的最终目标是当用户通过 Outlook 安排会议时，我将有一个应用程序来检索这些会议的详细信息。与会者名单和地点。

非常感谢任何指点！

Answer 1

我们需要将所需项目列表添加到属性集合，在给定的示例中，属性集合受到限制。在属性代码中

// Limit the properties returned to the appointment's subject, start time, and end time.
        cView.PropertySet = new PropertySet(AppointmentSchema.Subject, AppointmentSchema.Start, AppointmentSchema.End);

而不是上面使用下面的属性设置，cView.PropertySet = new PropertySet(AppointmentSchema.Subject, AppointmentSchema.Start, AppointmentSchema.End, AppointmentSchema.Location, AppointmentSchema.RequiredAttendees);

或者最适合初步学习的是

// Limit the properties returned to the appointment's subject, start time, and end time.
        cView.PropertySet = new PropertySet(BasePropertySet.FirstClassProperties);

中找到解决方案

代码可以进行整理，但它正确地取消了约会并允许我获取我需要的数据。

FindItemsResults<Item> result = service.FindItems(WellKnownFolderName.Calendar, new CalendarView(DateTime.Now, DateTime.Now.AddDays(7)));
            foreach(Item item in result.Items)
            {
                ServiceResponseCollection<GetItemResponse> itemResponseCollection = service.BindToItems(new[] { new ItemId(item.Id.UniqueId) }, new PropertySet(BasePropertySet.FirstClassProperties));
                foreach(GetItemResponse itemResponse in itemResponseCollection)
                {
                    Appointment appointment = (Appointment)itemResponse.Item;
                    Console.WriteLine("Subject: " + appointment.Subject);
                    Console.WriteLine("Location: " + appointment.Location);

                    Console.WriteLine("AppointmentType: " + appointment.AppointmentType.ToString());
                    Console.WriteLine("Body: " + appointment.Body);
                    Console.WriteLine("End: " + appointment.End.ToString());
                    Console.WriteLine("UniqueId: " + appointment.Id.UniqueId);
                    Console.WriteLine("Start: " + appointment.Start.ToString());
                    Console.WriteLine("When: " + appointment.When);

                    Console.WriteLine("Required Attendees: ");
                    foreach (var attendee in appointment.RequiredAttendees)
                    {
                        Console.WriteLine(attendee.Name);
                    }
                }
