使用Clipboard.GetFileDropList的控制台应用程序：如何检查是否来自剪切或复制操作？ [英] Console application using Clipboard.GetFileDropList: how to check if that came from a cut or copy operation?

问题描述

从 Windows资源管理器剪切/复制文件时，您可以获得该文件列表通过 Clipboard.GetFileDropList 方法。

When you cut/copy files from Windows Explorer, you can get that list of files through the Clipboard.GetFileDropList method.

如何确定该列表是来自剪切还是副本操作或通知另一方剪切/复制操作已完成？

How can you determine if that list came from a cut or copy operation or notify the other party that the cut/copy operation finished?

另一种方法：您可以使用以下命令将要剪切或复制的文件放在剪贴板上 Clipboard.SetFileDropList 方法。

这是关于控制台应用程序的，所以我无法监视Windows WM_CUT 或 WM_COPY 消息如 C＃文件-剪贴板中如何设置/读取哪个操作称为剪切或复制

This is about a console application, so I cannot monitor the Windows WM_CUT or WM_COPY messages as suggested by C# Files - in clipboard How to set/read which operation is called - Cut or Copy

推荐答案

您需要获取首选DropEffect格式的值（请参见 MSDN上的CFSTR_PREFERREDDROPEFFECT ）。它包含一个 STGMEDIUM ，其 hGlobal 字段指向一个DWORD值。如果此值为 DROPEFFECT_COPY ，则为复制操作；如果它是 DROPEFFECT_MOVE ，则为剪切操作。

You need to get the value for the "Preferred DropEffect" format (see CFSTR_PREFERREDDROPEFFECT on MSDN). It contains a STGMEDIUM whose hGlobal field points to a DWORD value. If this value is DROPEFFECT_COPY, it's a copy operation; if it's DROPEFFECT_MOVE, it's a cut operation.
