Exemples
Cette section contient deux exemples. Le premier exemple montre comment ouvrir des magasins X.509 standard et répertorier le nombre de certificats dans chacun d’eux.
Le deuxième exemple montre comment ajouter et supprimer des certificats uniques et des plages de certificats.
Exemple 1
Cet exemple tente d’ouvrir chaque magasin standard à chaque emplacement standard sur l’ordinateur actuel. Il affiche un résumé qui indique si chaque magasin existe et, le cas échéant, le nombre de certificats qu’il contient.
L’exemple crée un X509Store objet pour chaque combinaison de nom standard et d’emplacement standard. Il appelle la Open méthode avec l’indicateur OpenFlags.OpenExistingOnly , qui ouvre le magasin physique uniquement s’il existe déjà. Si le magasin physique existe, l’exemple utilise les Namepropriétés , Locationet Certificates pour afficher le nombre de certificats dans le magasin.

Remarques
Cette méthode retourne une instantané du magasin de certificats X.509. Notez que les opérations suivantes Add ou Remove effectuées sur le magasin n’auront aucun effet sur la collection retournée. Cette instantané est recalculée chaque fois que la propriété est appelée. L’utilisation de cette propriété à l’intérieur d’une fonction itérative n’est donc pas recommandée.
