无需P /调用。System.IO.File.GetAccessControl将返回一个FileSecurity对象，该对象具有GetOwner方法。
编辑：读取所有者非常简单，尽管它有点繁琐的API：
const string FILE = @"C:test.txt";var fs = File.GetAccessControl(FILE);var sid = fs.GetOwner(typeof(SecurityIdentifier));Console.WriteLine(sid); // SIDvar ntAccount = sid.Translate(typeof(NTAccount));Console.WriteLine(ntAccount); // DOMAINusername
设置所有者需要调用SetAccessControl来保存更改。另外，您仍然受Windows所有权规则的约束-
您不能将所有权分配给另一个帐户。您可以授予所有权烫发，而他们必须获得所有权。
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;}
