Remarques
Tous les membres ont un ensemble d’attributs, qui sont définis par rapport au type spécifique de membre.
Pour obtenir le MethodAttributes, commencez par obtenir le type . À partir du type , obtenez la méthode . À partir de la méthode , obtenez le MethodAttributes.
Notes pour les responsables de l’implémentation
Utilisez la Attributes propriété pour déterminer si une méthode est public
