             //   NTAccount account = new NTAccount("user01");
                DirectoryInfo dInfo = new DirectoryInfo("c:\\1.txt");
                DirectorySecurity oDirectorySecurity = dInfo.GetAccessControl(AccessControlSections.Owner);                //SecurityIdentifier sid2 = (SecurityIdentifier)oDirectorySecurity.GetOwner(typeof(SecurityIdentifier)); //文件夹的所有者SID
                //Console.WriteLine(sid2.ToString());                NTAccount account2 = (NTAccount)oDirectorySecurity.GetOwner(typeof(NTAccount));                Console.WriteLine(account2.ToString());                //oDirectorySecurity.SetOwner(account);
                //dInfo.SetAccessControl(oDirectorySecurity);            }
            catch (Exception e)
