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

An ACL describes individuals and/or groups who have, or do not have, rights to specific actions on the given file. For more information, see 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 code example uses the GetAccessControl and the SetAccessControl methods to add and then remove an access control list (ACL) entry from a file. You must supply a valid user or group account to run this example.
