C# – How to create a directory in which only Administrator has full control?

I’ve created in C# a program which create a directory and some files inside it.

How can I set (programmatically – if possible) the Full-Control right only for Administrator? The ideal case would be to inhibit the Write and Read rights for a non-administrator user (creating a "kind of hidden folder"), but it would also be enough for me to set only the Read right for a non-administrator user, stop.

Thank you.

Please, I’ve tried to search in StackOverflow, but nobody has wrote the same problem. Infact, everybody talks about "all users". Me no.

Yup, it’s possible. First, you have to create the directory then set it’s access rules.

var directory = Directory.CreateDirectory("SomeFolder");

var directorySecurity = directory.GetAccessControl();

var administratorRule = new FileSystemAccessRule("Administrators", FileSystemRights.FullControl, InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.None, AccessControlType.Allow);
var usersRole = new FileSystemAccessRule("Users", FileSystemRights.CreateDirectories | FileSystemRights.CreateFiles, AccessControlType.Allow);

directorySecurity.AddAccessRule(administratorRule);
directorySecurity.AddAccessRule(usersRole);

directory.SetAccessControl(directorySecurity);
