Remarques

Le FileSystemAccessRule classe représente une abstraction d’une entrée de contrôle d’accès (ACE) sous-jacente qui spécifie un compte d’utilisateur, le type d’accès à fournir (lecture, écriture et ainsi de suite) et s’il faut autoriser ou refuser ce droit.The FileSystemAccessRule class represents an abstraction of an underlying access control entry (ACE) that specifies a user account, the type of access to provide (read, write, and so on), and whether to allow or deny that right. Cette classe peut également spécifier comment les règles d’accès sont propagées aux objets enfants.This class can also specify how access rules are propagated to child objects.

Utilisez la FileSystemAccessRule classe pour créer une nouvelle règle d’accès.Use the FileSystemAccessRule class to create a new access rule. Vous pouvez conserver la règle à l’aide de la FileSecurity ou DirectorySecurity classe.You can persist the rule using the FileSecurity or DirectorySecurity class.
