我有一个要求读取和显示文件（用于审计）的拥有者，并有可能改变它，以及（这是次要的要求）。是否有任何好的C＃包装？

I have a requirement to read and display the owner of a file (for audit purposes), and potentially changing it as well (this is secondary requirement). Are there any nice C# wrappers?

在一个快速谷歌，我发现只有the WMI的解决方案和建议，PInvoke的GetSecurityInfo

After a quick google, I found only the WMI solution and a suggestion to PInvoke GetSecurityInfo

推荐答案

没有必要的P / Invoke。 System.IO.File.GetAccessControl将返回一个FileSecurity对象，它具有一个GetOwner方法。

No need to P/Invoke. System.IO.File.GetAccessControl will return a FileSecurity object, which has a GetOwner method.

编辑：阅读的所有者是pretty的简单，但它是一个有点笨重的API的：

Reading the owner is pretty simple, though it's a bit of a cumbersome API:

const string FILE = @"C:\test.txt"; var fs = File.GetAccessControl(FILE); var sid = fs.GetOwner(typeof(SecurityIdentifier)); Console.WriteLine(sid); // SID var ntAccount = sid.Translate(typeof(NTAccount)); Console.WriteLine(ntAccount); // DOMAIN\username

设置所有者需要调用SetAccessControl保存更改。此外，你仍然受所有制的Windows规则 - 你不能分配所有权到另一个帐户。你可以给取得所有权烫发，他们必须采取所有权。

Setting the owner requires a call to SetAccessControl to save the changes. Also, you're still bound by the Windows rules of ownership - you can't assign ownership to another account. You can give take ownership perms, and they have to take ownership.

var ntAccount = new NTAccount("DOMAIN", "username"); fs.SetOWner(ntAccount); try { File.SetAccessControl(FILE, fs); } catch (InvalidOperationException ex) { Console.WriteLine("You cannot assign ownership to that user." + "Either you don't have TakeOwnership permissions, or it is not your user account." ); throw; }
