Hello
You may have to set the InheritanceFlags as well.

Example:

C#

DirectorySecurity dirsec = null;
DirectoryInfo dir = new DirectoryInfo(@"C:\temp");
String identity = "SomeUsername";

dirsec = dir.GetAccessControl(AccessControlSections.Access);

rule = new FileSystemAccessRule(identity, FileSystemRights.FullControl | FileSystemRights.Synchronize, AccessControlType.Allow);

dirsec.AddAccessRule(rule);

rule = new FileSystemAccessRule(identity, FileSystemRights.FullControl | FileSystemRights.Synchronize, InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.InheritOnly, AccessControlType.Allow);

dirsec.AddAccessRule(rule);

dir.SetAccessControl(dirsec);

Also ensure that the user/account running the application has the privileges to set access control.
If you get an exception, feel free to post it :-)

I hope that helps...
