本文介绍了获取指向“链接"的路径(又名“收藏夹")文件夹的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
更新:
因此，我在完成所有这些工作后发现，似乎用户文件夹中的链接"文件夹可以命名为ANYTHING，您仍然可以通过以下方式访问它:C:\ Users(用户名)\ Links
So I just found out in doing all this leg work that it seems the "Links" folder in your user folder can be named ANYTHING and you can still access it by going to "C:\Users(username)\Links"
例如:重命名
"C:\Users\(username)\Links"
到
"C:\Users\(username)\MyNewLinksFolder"
然后尝试浏览到...
Then try to browse to...
"C:\Users\(username)\Links"
(前额为手掌)
Windows 7文件浏览器树中有一个收藏夹"节点:
There is a "Favorites" node in the Windows 7 file explorer tree:
这些收藏夹的路径(默认情况下)在这里:
The path to those favorites (by default) is here:
我希望能够通过C#代码获取此路径.我希望使用Environment.SpecialFolder枚举，但这似乎很麻烦！我不能依赖始终位于以下位置的文件夹:
I want to be able to get this path via c# code. I was hoping to use the Environment.SpecialFolder Enum but that seems to be a wash! I can't depend on the folder always residing at:
c:\users\[username]\Links
...因为任何人都可以更改该目录名，所以它仍然可以正常工作，因此我的硬编码路径将毫无用处.
... because anyone could change that directory name, it still work correctly and then my hardcoded path would be useless.
所以！我的问题是，如何在不使用硬编码字符串的情况下让C#返回该路径? 我也希望能够获得这些项目的图标！
So! My question is, how can I get c# to return that path without using a hardcoded string? I would also like to be able to get those items icons as well!
谢谢！
推荐答案
只想分享我的想法.我创建了一些可以帮助其他人的类，函数等...
Just wanted to share what I came up with. I created a few classes, functions etc that might help others out...
注意:-您需要将WinAPIs引用添加到您的项目中，因为它位于不同的命名空间中.-在我的情况下，SpecialFolders.cs包含在名为"FileFolderWorker"的名称空间中，因此请确保您从同一名称空间调用该函数(如以下用法中所示)，否则您也将需要使用语句，如以下用法"区域中所述
NOTES:- You need to add the WinAPIs reference to your project because it's in a different namespace.- In my case SpecialFolders.cs is contained in a namespace called "FileFolderWorker" so make sure you are calling the function (shown in Usage below) from the same namespace or you will need a using statement as depicted in the Usage area below as well.
