Remarques
Bien que la OutArgs propriété soit redondante, car les mêmes fonctionnalités peuvent être obtenues via le champ et GetOutArg la OutArgCount méthode, une optimisation des performances peut être disponible si l’implémenteur comprend quand tous les arguments seront récupérés.
Avertissement
Si Exception n’est pas null
, une System.IndexOutOfRangeException exception est levée lors de l’accès OutArgs .
