从此question

File.Copy(@"1.txt", @"2.txt", true);
string userName = System.IO.File.GetAccessControl(@"1.txt").GetOwner(typeof(System.Security.Principal.NTAccount)).ToString();
var fs = File.GetAccessControl(@"2.txt");
var ntAccount = new NTAccount("DOMAIN", userName);
fs.SetOWner(ntAccount);

try {
   File.SetAccessControl(@"2.txt", 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;
}
