Use the GetAccessControl method to retrieve the access control list (ACL) entries for a directory.

An ACL describes individuals and/or groups who have, or do not have, rights to specific actions on the given file or directory. For more information, see ACL Technology Overview and How to: Add or Remove Access Control List Entries.

In NTFS environments, ReadAttributes and ReadExtendedAttributes are granted to the user if the user has ListDirectory rights on the parent folder. To deny ReadAttributes and ReadExtendedAttributes, deny ListDirectory on the parent directory.

The following example uses the GetAccessControl and the SetAccessControl methods to add an access control list (ACL) entry and then remove an ACL entry from a directory. You must supply a valid user or group account to run this example.
