获取路径＆＃34;链接＆＃34; （AKA收藏夹）文件夹

Question

更新

所以我发现做了所有这些腿部工作，它似乎是＆＃34;链接＆＃34;您的用户文件夹中的文件夹可以命名为ANYTHING，您仍然可以通过转到＆＃34; C：\ Users（用户名）\链接＆＃34;

来访问它

例如：重命名

"C:\Users\(username)\Links"

到

"C:\Users\(username)\MyNewLinksFolder"

然后尝试浏览...

"C:\Users\(username)\Links"

（额头到掌心）

有一个＆＃34;收藏夹＆＃34; Windows 7文件资源管理器树中的节点：

这些收藏夹的路径（默认情况下）位于：

我希望能够通过c＃代码获取此路径。我希望使用Environment.SpecialFolder Enum，但这似乎是一个洗！我不能依赖于总是驻留在的文件夹：

c:\users\[username]\Links

...因为任何人都可以更改该目录名称，它仍能正常工作，然后我的硬编码路径将毫无用处。

原来如此！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图标！

谢谢！

Answer 1

只是想分享我想出的东西。我创建了一些可能帮助其他人的类，函数等......

注意： - 您需要将WinAPIs引用添加到项目中，因为它位于不同的命名空间中。 - 就我而言，SpecialFolders.cs包含在名为＆＃34; FileFolderWorker＆＃34;的名称空间中。因此，请确保从相同的命名空间调用该函数（如下面的用法所示），否则您将需要一个using语句，如下面的Usage区域所示。

using FileFolderWorker;
SpecialFolders.DebugShowAllFolders();

Answer 2

唯一适用的环境变量是％userprofile％，它会替换路径中除链接子文件夹以外的所有内容：

%userprofile%\Links

我认为有一个包含完整路径的注册表项，如果你想要阅读它，我会环顾四周，看看我是否记得它在哪里。

<强> 修改

我可以确认@Malk的评论（虽然我还无法评论）完整路径存储在注册表项HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Shell文件夹{BFB9D5E0-C6A9-404C-B2B2-AE6DB6AF4968 }

Answer 3

Environment.GetFolderPath实际上会调用SHGetFolderPath。 SpecialFolder枚举包含用户个人资料文件夹下的多个文件夹，但不包含Links文件夹。要获取Links文件夹，您需要使用名为SHGetKnownFolderPath的新API。这是MSDN的链接：http://msdn.microsoft.com/en-us/library/windows/desktop/bb776911(v=vs.85).aspx

Links文件夹的指南是{bfb9d5e0-c6a9-404c-b2b2-ae6db6af4968}。您可以在此处找到它：http://msdn.microsoft.com/en-us/library/windows/desktop/dd378457(v=vs.85).aspx

然而，似乎内置.net类库中没有SHGetKnownFolderPath。你必须P / Invoke它。

编辑：要获取图标，您可以在文件夹中查找desktop.ini文件。它包含DLL和资源ID用作文件夹图标的信息。
