Voorbeelden

In het volgende voorbeeld wordt een klasse met de naam van Group een bestand met de naam UnknownAttributes.xmlgedeserialiseerd. Wanneer een element wordt gevonden in het bestand dat geen corresponderend lid in de klasse heeft, vindt de UnknownAttribute gebeurtenis plaats. Als u het voorbeeld wilt proberen, plakt u de volgende XML-code in een bestand met de naam UnknownAttributes.xml.

<?xml version="1.0" encoding="utf-8"?>
<Group xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" GroupType = 'Technical' GroupNumber = '42' GroupBase = 'Red'>
  <GroupName>MyGroup</GroupName>
</Group>
