.NET中的注册表：DeleteSubKeyTree表示该子项不存在，但是嘿，确实如此！(Registry in .NET: DeleteSubKeyTree says the subkey does not exists, but hey, it does!)

尝试删除子项目树： HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.hdr 。 .hdr子键有一个子键，没有值。 所以我用这个代码：

RegistryKey FileExts = Registry.CurrentUser.CreateSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Explorer\\FileExts"); RegistryKey faulty = FileExts.OpenSubKey(".hdr"); Debug.Assert (faulty != null && faulty.SubKeyCount != 0); faulty.Close(); FileExts.DeleteSubKeyTree(".hdr");

我收到ArgumentException消息“无法删除子项树，因为该子项不存在。”

WTF？ 我检查并断言它确实存在？

状态更新

在使用Process Monitor时，“.hdr”的子项在运行代码时会收到ACCESS DENIED错误。 我检查了自动调整，但它们看起来很好吗？

Trying to delete a subkey tree: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.hdr. .hdr subkey has one subkey, no values. So I use this code:

RegistryKey FileExts = Registry.CurrentUser.CreateSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Explorer\\FileExts"); RegistryKey faulty = FileExts.OpenSubKey(".hdr"); Debug.Assert (faulty != null && faulty.SubKeyCount != 0); faulty.Close(); FileExts.DeleteSubKeyTree(".hdr");

And I get the ArgumentException with message "Cannot delete a subkey tree because the subkey does not exist."

WTF? I checked and asserted it did exist?

Status update

Seeking with Process Monitor, the subkey of ".hdr" gets a ACCESS DENIED error when running the code. I checked the autorizations, but they look fine?

最满意答案

找到了解决方案，引发了另一个问题......

在使用Process Monitor指出ACCESS DENIED错误后，我只是尝试单独删除子键：

RegistryKey hdr = FileExts.OpenSubKey(".hdr", true); foreach (String key in hdr.GetSubKeyNames()) hdr.DeleteSubKey(key); hdr.Close(); FileExts.DeleteSubKeyTree(".hdr");

它工作正常，所以这不是一个许可问题！

由于我不理解的原因，DeleteSubKeyTree需要一个空树来工作。

一个解释，有人吗？

Found a solution, which raises other another question...

After pointing the ACCESS DENIED error with Process Monitor, I just tried to delete subkeys individually:

RegistryKey hdr = FileExts.OpenSubKey(".hdr", true); foreach (String key in hdr.GetSubKeyNames()) hdr.DeleteSubKey(key); hdr.Close(); FileExts.DeleteSubKeyTree(".hdr");

It worked fine, so it's not a permission problem!

For a reason I don't understand, DeleteSubKeyTree needed an empty tree to work.

An explanation, anyone?
