Hooking my program with windows explorer's rename event
提问by pek
Is there any way, in any language, to hook my program when a user renames a file?
当用户重命名文件时，有什么方法可以用任何语言挂钩我的程序吗？
For example: A user renames a file and presses enter (or clicks away) to confirm the rename action. BEFORE the file is actually renamed, my program "listens" to this event and pops up a message saying "Are you sure you want to rename C:\test\file.txt to C:\test\test.txt?".
例如：用户重命名文件并按 Enter（或单击离开）以确认重命名操作。在文件实际重命名之前，我的程序“侦听”此事件并弹出一条消息，提示“您确定要将 C:\test\file.txt 重命名为 C:\test\test.txt？”。
I'm thinking/hoping this is possible with C++, C# or .NET.. But I don't have any clue where to look for.
我在想/希望 C++、C# 或 .NET 可以实现这一点。但我不知道在哪里寻找。

You can probably solve this by using the FileSystemWatcher classin .NET framework.
您可以通过使用.NET 框架中的FileSystemWatcher 类来解决这个问题。
From the class remarks:
来自课堂评论：
You can watch for renaming, deletion, or creation of files or directories. For example, to watch for renaming of text files, set the Filter property to "*.txt" and call the WaitForChanged method with a Renamed specified for its parameter.
您可以监视文件或目录的重命名、删除或创建。例如，要监视文本文件的重命名，请将 Filter 属性设置为“*.txt”并使用为其参数指定的 Renamed 调用 WaitForChanged 方法。

My guess is that this is notpossible, I did find thiswhich is for monitoring operations (including rename) on a folder, but there does not appear to be a similar method for files.
我的猜测是，这是没有可能的，我也发现这是一个文件夹监控操作（包括重命名），但似乎没有成为文件类似的方法。
@Richard, FileSystemWatcher is good if you only need to monitor changes, but he needs to interrupt them which it cannot do.
@Richard，如果您只需要监视更改，则 FileSystemWatcher 很好，但他需要中断它们，而它无法做到。

IFileOperationProgressSink.PreRenameItemis the closest supported thing I know of. Unfortunately, it's not a hook into Explorer - so you can only use it for your own IFileOperationactions. Depending on your needs, you can write a shell extension to do your own ConfirmRename(or something), and branch from there.
IFileOperationProgressSink.PreRenameItem是我所知道的最接近支持的东西。不幸的是，它不是资源管理器的挂钩 - 因此您只能将它用于您自己的IFileOperation操作。根据您的需要，您可以编写一个 shell 扩展来完成您自己的ConfirmRename（或其他）操作，并从那里分支。
Otherwise, you're looking at hooking SHFileOperation, I think. This would have to be done in unmanaged code, as you'll be loaded into Explorer.exe. For Vista, this has been changed to IFileOperation- which probably means you'll have to hook the creation of it and pass out your mock.
否则，你正在寻找 hooking SHFileOperation，我想。这必须在非托管代码中完成，因为您将被加载到 Explorer.exe。对于 Vista，这已更改为IFileOperation- 这可能意味着您必须挂钩它的创建并传递您的模拟。
Personally, I think since you're talking a rename, wilhelmtell's ideaof confirming afterthe change, and undoing it if necessary is the best idea.
就我个人而言，我认为既然您在谈论重命名，那么 wilhelmtell在更改后确认并在必要时撤消它的想法是最好的主意。
