Taking ownership of a file or folder
提问by Steinthor.palsson
Before I pull out the rest of my hair I'd like to get some input on this.
I'm trying to take ownership of a folder. I'm running the program as administrator of course and I do have rights to take ownership since I can change the owner in explorer.
在我拔出其余的头发之前，我想就此获得一些意见。
我正在尝试取得文件夹的所有权。我当然以管理员身份运行该程序，并且我确实有权获得所有权，因为我可以在资源管理器中更改所有者。
I can however change the owner if either administrator or my account owns it, and I can change permissions if I already have ownership.
If I try to give myself ownership of a file, lets say owned by SYSTEM, then I get an unauthorizedexception.
但是，如果管理员或我的帐户拥有它，我可以更改所有者，如果我已经拥有所有权，我可以更改权限。
如果我尝试给自己一个文件的所有权，比如说由 SYSTEM 拥有，那么我会得到一个未经授权的异常。
I've tried some different things with the accesscontrol methods but nothing works, this latest method I think is directly by the book.
我已经用访问控制方法尝试了一些不同的东西，但没有任何效果，我认为这个最新的方法直接来自这本书。
private static void makePerm(string file, NTAccount account)
{
FileInfo finfo = new FileInfo(file);
FileSecurity fsecurity = finfo.GetAccessControl();
//also tried it like this //fsecurity.ResetAccessRule(new FileSystemAccessRule(string.Format(@"{0}\{1}", Environment.UserDomainName.ToString(), Environment.UserDomainName.ToString()), FileSystemRights.FullControl, AccessControlType.Allow));
fsecurity.SetOwner(account);
finfo.SetAccessControl(fsecurity);
}
I'm trying this on Windows 7 btw.
What am I missing here?
顺便说一句，我正在 Windows 7 上尝试此操作。
我在这里错过了什么？

I had the same problem and just posting here for anybody else who may come here searching like me:
我遇到了同样的问题，只是在这里发布给可能像我一样来这里搜索的其他人：
You need to explicitly enable SeTakeOwnershipPrivilege in code as Luke mentions above. I found this Process Privilegesto be really helpful dealing with this sort of thing.
正如 Luke 上面提到的，您需要在代码中显式启用 SeTakeOwnershipPrivilege。我发现这个进程特权对于处理这类事情真的很有帮助。
Here is how it fixed my code:
这是它修复我的代码的方法：
using System;
using System.Diagnostics;
// ...
using (new ProcessPrivileges.PrivilegeEnabler(Process.GetCurrentProcess(), Privilege.TakeOwnership))
{
directoryInfo = new DirectoryInfo(path);
directorySecurity = directoryInfo.GetAccessControl();
directorySecurity.SetOwner(WindowsIdentity.GetCurrent().User);
Directory.SetAccessControl(path, directorySecurity);
}

Did you elevate your process via UAC first? On Windows 7, without UAC escalation, your process is running with the lower privileged token.
您是否首先通过 UAC 提升了流程？在 Windows 7 上，如果没有 UAC 升级，您的进程将使用较低特权的令牌运行。
