Uwagi

Wszystkie elementy członkowskie mają zestaw atrybutów zdefiniowanych w odniesieniu do określonego typu elementu członkowskiego.

Aby uzyskać element MethodAttributes, najpierw uzyskaj typ . Z typu pobierz metodę . Z metody pobierz metodę MethodAttributes.

Uwagi dotyczące implementowania

Attributes Użyj właściwości , aby określić, czy metoda to public, private, final, virtualitd.
