While the FileStream class and GetAccessControl can be used to retrieve the access control list (ACL) entries of an existing file, consider using File.GetAccessControl method, as it is easier to use.

Use the GetAccessControl method to retrieve the 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 ACL Technology Overview and How to: Add or Remove Access Control List Entries.
