  • Hi Pallavi Ganesh,

    Thank you for posting here.

    For your question, you could try the code below to get the users of specified directory permissions except Administrators and SYSTEM. All the path would be okay not only for shared files.

     class Program
            static void Main(string[] args)
            public static List<Account> GetDirectoryAccountSecurity(string DirName)
                List<Account> account = new List<Account>();
                DirectoryInfo dInfo = new DirectoryInfo(DirName);
                if (dInfo.Exists)
                    DirectorySecurity sec = Directory.GetAccessControl(DirName, AccessControlSections.All);
                    foreach (FileSystemAccessRule rule in sec.GetAccessRules(true, true, typeof(System.Security.Principal.NTAccount)))
                        if (rule.IdentityReference.Value != @"NT AUTHORITY\SYSTEM" && rule.IdentityReference.Value != @"BUILTIN\Administrators")
                            Account acc = new Account()
                                UserName = rule.IdentityReference.Value,
                                Permission = rule.FileSystemRights.ToString()
                return account;
        public class Account
            public string UserName { get; set; }
            public string Permission { get; set; }

    My shared folder
