如何从 ContextMenu 获取 Outlook 约会

Question

我已将 ContextMenuItem 添加到 Outlook 约会的上下文菜单。

问题是我不知道如何获取 Appointment 对象。如果我得到一个 IRibbonControl，它的 Context 属性应该包含 Appointment，但它包含一个 Selection。据我所知，我无法使用选择到达约会。

有人知道如何获得预约吗？

Selection 对象包含在图片上选择的 AppointmentItem 对象。例如：

                Object selObject = Selection[1];
                if (selObject is Outlook.MailItem)
                {
                    Outlook.MailItem mailItem =
                        (selObject as Outlook.MailItem);
                    itemMessage = "The item is an e-mail message." +
                        " The subject is " + mailItem.Subject + ".";
                    mailItem.Display(false);
                }
                else if (selObject is Outlook.ContactItem)
                {
                    Outlook.ContactItem contactItem =
                        (selObject as Outlook.ContactItem);
                    itemMessage = "The item is a contact." +
                        " The full name is " + contactItem.Subject + ".";
                    contactItem.Display(false);
                }
                else if (selObject is Outlook.AppointmentItem)
                {
                    Outlook.AppointmentItem apptItem =
                        (selObject as Outlook.AppointmentItem);
                    itemMessage = "The item is an appointment." +
                        " The subject is " + apptItem.Subject + ".";
                }
                else if (selObject is Outlook.TaskItem)
                {
                    Outlook.TaskItem taskItem =
                        (selObject as Outlook.TaskItem);
                    itemMessage = "The item is a task. The body is "
                        + taskItem.Body + ".";
                }
                else if (selObject is Outlook.MeetingItem)
                {
                    Outlook.MeetingItem meetingItem =
                        (selObject as Outlook.MeetingItem);
                    itemMessage = "The item is a meeting item. " +
                         "The subject is " + meetingItem.Subject + ".";
                }

Answer 2

不要不要在弹出菜单事件处理程序中使用Explorer.Selection - 可以select消息，然后在不 select 的情况下右键单击另一条消息。 Explorer.Selection 集合不会更改，并且 Explorer.SelectionChange 事件不会触发。

当您处理事件处理程序时，上下文参数将传递给您。将其投射到 Selection 对象并改为使用它。该集合将不同于 Explorer.Selection 对象。
