Remarques

L’appel de cette surcharge de méthode équivaut à appeler la surcharge de méthode GetAccessControl et en spécifiant les sections de contrôle d’accès AccessControlSections.Access | AccessControlSections.Owner | | AccessControlSections.Group (AccessControlSections.AccessOrAccessControlSections.OwnerOrAccessControlSections.Group dans Visual Basic).

Une liste de contrôle d’accès décrit les individus et les groupes qui ont, ou n’ont pas, des droits pour des actions spécifiques sur le fichier ou le répertoire donné. Pour plus d’informations, consultez Comment : ajouter ou supprimer des entrées de liste de contrôle d’accès.
