Cette surcharge définit la ElementName propriété.

Utilisez cette surcharge si vous souhaitez que le nom de l’élément XML généré diffère de l’identificateur du membre.

Un document XML qui inclut des espaces de noms peut contenir plusieurs versions d’un nom d’élément. Pour plus d'informations, consultez la propriété ElementName.
