Outlook 2013 加载项 - "Popped in" window 电子邮件回复和转发：接口类型是什么？

Question

我一直在为Outlook 2013开发一个插件，目前发现很难找到Outlook 2013回复和转发邮件时出现的"Popped in" window的界面类型.

例如：对于新邮件，接口类型是Outlook.MailItem，对于会议请求，接口类型是Outlook.AppointmentItem。

我可以使用什么界面类型来识别在 Outlook 2013 中回复和转发时出现的 window 中的弹出消息？

当您回复或转发邮件项目时，新项目将是一个 MailItem 对象。您可以使用以下代码来确定项目类型：

        Object selObject = this.Application.ActiveExplorer().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 + ".";
        }

您也可以考虑检查 MailItem class 的 MessageClass 属性。 MessageClass 属性 将项目链接到它所基于的表单。选择项目后，Outlook 使用消息 class 来定位表单并公开其属性，例如回复命令。

我的经理和我坐在一起解决了这个问题，幸运的是找到了解决方案。您可以使用以下代码

访问"popped in"回复和转发windows

//First, declare the interface type of Explorer
public static Outlook.Explorer currentExplorer;

//Create a method to identify the Inline response as a MailItem
    private void ThisAddIn_InlineResponse(object Item)
    {
        if (Item != null)
        {
            Outlook.MailItem mailItem = Item as Outlook.MailItem;
        }
    }

//Direct to the ThisAddIn_Startup() method and add an event handler for the Inline Response Method

currentExplorer.InLineResponse += ThisAddIn_InLineResponse;

//Access the popped in reply and forward window where required
object item = null;
item = currentExplorer.ActiveInlineResponse;
