推荐答案

Hello Jacob，

Hello Jacob,

Outlook对象模型（也不是VSTO） 没有提供任何用于检测此类操作的内容。您可以考虑处理

SelectionChange 当用户以编程方式选择不同的或附加的Microsoft Outlook项目或通过与用户界面交互时触发的Explorer类的事件。
当用户（通过编程方式或通过用户界面）单击或切换到包含项目的其他文件夹时，也会发生此事件，因为Outlook会自动选择第一个项目该文件夹。

The Outlook object model (nor VSTO) doesn't provide anything for detecting such operations. You may consider handling the SelectionChange event of the Explorer class which is fired when the user selects a different or additional Microsoft Outlook item programmatically or by interacting with the user interface. This event also occurs when the user (either programmatically or via the user interface) clicks or switches to a different folder that contains items, because Outlook automatically selects the first item in that folder.

Public WithEvents myOlExp As Outlook.Explorer 
 
Public Sub Initialize_handler()  
 Set myOlExp = Application.ActiveExplorer  
End Sub  
 
Private Sub myOlExp_SelectionChange()  
 MsgBox myOlExp.Selection.Count & " items selected."  
End Sub
