临时更改文件夹/文件的图标 [英] Temporarily change icon of a folder/file

问题描述

我想知道.net中是否有一种方法可以将文件夹/文件的图标临时更改为不同于常规文件/文件夹的图标.我正在创建一个需要监视文件夹/文件内活动的应用程序，这可以通过FileSystemWatcher来实现，但是我的要求是，在监视文件/文件夹时，它会带有一个勾号"来更改其图标.我不知道除了默认的Windows图标之外，是否还可以将图标临时更改为绿色的勾号，我不需要为所有此类文件类型在Windows注册表中更改文件显示图标.

I wonder if there is a way in .net to temporarily change icon of a folder/file to something different than regular file/folder icon. I am creating an application that reqires to monitor activities inside folder/file, this can be achieved by FileSystemWatcher but my requirement is to change the icon of the files/folder with a Tick Mark when it is monitored. I wonder if there is a way to temporarily change the icon to green tick mark in addition to the default windows icon , I do not need to change the file display icons in windows registry for all such file types.
