Remarques

La date d’expiration est la date après laquelle le certificat X.509 n’est plus considéré comme valide.

La GetExpirationDateString méthode retourne une chaîne qui affiche la date mise en forme dans Modèle de date courte suivie de l’heure mise en forme dans Modèle de temps long. La date et l’heure sont mises en forme à l’aide de la culture et du fuseau horaire actuels.
