Définition

Recherche toutes les règles de contrôle d'accès ayant les mêmes utilisateur et AccessControlType (autorisation ou refus) que la règle spécifiée et, s'il en existe, les supprime.Searches for all access control rules with the same user and AccessControlType (allow or deny) as the specified rule and, if found, removes them.

Public Sub RemoveAccessRuleAll (rule As SemaphoreAccessRule)

Paramètres

rule
SemaphoreAccessRule SemaphoreAccessRule SemaphoreAccessRule SemaphoreAccessRule

SemaphoreAccessRule qui spécifie l'utilisateur et AccessControlType à rechercher.A SemaphoreAccessRule that specifies the user and AccessControlType to search for. Tous les droits spécifiés par cette règle sont ignorés.Any rights specified by this rule are ignored.

Exceptions

Exemples

L’exemple de code suivant montre que RemoveAccessRuleAll la méthode supprime toutes les règles qui correspondent AccessControlTypeà l’utilisateur et, en ignorant les droits.The following code example shows that the RemoveAccessRuleAll method removes all rules that match user and AccessControlType, ignoring rights.

L’exemple crée un SemaphoreSecurity objet, ajoute des règles qui autorisent et refusent divers droits pour l’utilisateur actuel, puis fusionne les droits Allow supplémentaires dans la règle.The example creates a SemaphoreSecurity object, adds rules that allow and deny various rights for the current user, and then merges additional rights into the Allow rule. L’exemple crée ensuite une nouvelle règle qui permet à l’utilisateur actuel d’appropriation et utilise cette règle pour supprimer la Allow règle de l' SemaphoreSecurity objet.The example then creates a new rule that allows the current user to take ownership, and uses that rule to remove the Allow rule from the SemaphoreSecurity object.

Notes

Cet exemple n’attache pas l’objet de sécurité à Semaphore un objet.This example does not attach the security object to a Semaphore object. Des exemples qui attachent des objets de sécurité Semaphore.GetAccessControl sont Semaphore.SetAccessControldisponibles dans et.Examples that attach security objects can be found in Semaphore.GetAccessControl and Semaphore.SetAccessControl.

Remarques

Les règles SemaphoreSecurity ayant le même utilisateur et la même AccessControlType valeur que rulesont recherchées dans l’objet actuel.The current SemaphoreSecurity object is searched for rules that have the same user and the same AccessControlType value as rule. Les droits spécifiés rule par sont ignorés lors de l’exécution de cette recherche.Any rights specified by rule are ignored when performing this search. Si aucune règle correspondante n’est trouvée, aucune action n’est effectuée.If no matching rules are found, no action is taken.
