Hinweise

Alle Elemente verfügen über eine Reihe von Attributen, die in Bezug auf den jeweiligen Elementtyp definiert sind.All members have a set of attributes, which are defined in relation to the specific type of member.

Um das MethodAttributeszu erhalten, erhalten Sie zuerst den-Typ.To get the MethodAttributes, first get the type. Get the-Methode aus dem-Typ.From the type, get the method. In der-Methode erhalten Sie MethodAttributesdie.From the method, get the MethodAttributes.

Hinweise für Vererber

Verwenden Sie Attributes die-Eigenschaft, um zu bestimmen public, ob eine virtualMethode, private, final, usw. ist.Use the Attributes property to determine whether a method is public, private, final, virtual, and so on.
