Voorbeelden

In het volgende voorbeeld wordt een klasse met de naam Groupserialiseren. De SoapTypeAttribute wordt toegepast op de klasse, waarbij de TypeName set is ingesteld op 'SoapGroupType'. Het SoapTypeAttribute wordt ook overschreven, het wijzigen van het TypeName 'Team'. Beide versies worden geserialiseerd, wat resulteert in twee bestanden: SoapType.xml en SoapType2.xml.

Opmerkingen

De SoapTypeAttribute klasse behoort tot een reeks kenmerken die bepalen hoe een XmlSerializer object wordt geserialiseerd of gedeserialiseerd als gecodeerde SOAP XML. De resulterende XML voldoet aan sectie 5 van het World Wide Web Consortium-document, SOAP (Simple Object Access Protocol) 1.1. Zie Attributes That Control Encoded SOAP Serialization voor een volledige lijst met vergelijkbare kenmerken.

Als u een object wilt serialiseren als een gecodeerd SOAP-bericht, maakt u het XmlSerializer met behulp van een XmlTypeMapping object dat is gemaakt met de ImportTypeMapping methode van de SoapReflectionImporter klasse.

De SoapTypeAttribute kan alleen worden toegepast op klassedeclaraties.

De IncludeInSchema eigenschap bepaalt of het resulterende XML-elementtype is opgenomen in het XML-schemadocument (.xsd) voor de gegenereerde XML-stroom. Als u het schema wilt zien, compileert u de klasse in een DLL-bestand. Geef het resulterende bestand door als een argument aan het XML Schema Definition Tool (Xsd.exe).> Het hulpprogramma genereert het XML-schema voor de XML-stroom die wordt gegenereerd wanneer de klasse wordt geserialiseerd door een exemplaar van de XmlSerializer klasse.

Als u een andere naamruimte instelt, wordt Xsd.exe een ander schemabestand (.xsd) geschreven voor de XML-stroom die wordt gegenereerd wanneer de klasse wordt geserialiseerd.
