Voorbeelden

In het volgende voorbeeld wordt een klasse met de naam Groupgedefinieerd, die een veld bevat dat Employees een matrix met Employee objecten retourneert. In het voorbeeld wordt de Manager klasse afgeleid van de Employee klasse en wordt de XmlIncludeAttribute klasse toegepast op de Employee klasse. Wanneer in het voorbeeld een Group object wordt gemaakt, wordt er een Manager object in de Employee matrix ingevoegd. Ten slotte serialiseert het voorbeeld het Group object.
