Příklady

Následující příklad používá XmlSerializer k serializaci třídy pojmenované Food , která obsahuje výčet pojmenovaný FoodType. Výčet FoodType se přepíše vytvořením SoapEnumAttribute výčtu pro jednotlivé výčty a nastavením SoapEnum vlastnosti SoapAttributes na SoapEnumAttributehodnotu . Přidá SoapAttributes se do objektu SoapAttributeOverrides , který se používá k vytvoření XmlSerializer.

Poznámky

Třída SoapEnumAttribute patří do řady atributů, které řídí, jak XmlSerializer serializuje nebo deserializuje objekt jako kódovaný KÓD SOAP XML. Výsledný XML odpovídá části 5 dokumentu Simple Object Access Protocol (SOAP) 1.1 v dokumentu World Wide Web Consortium. Úplný seznam podobných atributů najdete v tématu Atributy, které řídí kódované serializace SOAP.

Chcete-li serializovat objekt jako kódovanou zprávu SOAP, musíte vytvořit XmlSerializer pomocí XmlTypeMapping vytvořené metody ImportTypeMapping SoapReflectionImporter třídy.

SoapEnumAttribute Použijte k změně výčtu, který XmlSerializer generuje nebo rozpozná (když serializuje nebo deserializuje třídu, v uvedeném pořadí). Pokud například výčet obsahuje člena s názvem One, ale dáváte přednost tomu, že má výstup XML název Single, použijte SoapEnumAttribute u člena výčtu a nastavte Name vlastnost na "Single".

Hodnotu vlastnosti objektu a vlastnost můžete přepsat Name vytvořením instance SoapEnumAttribute třídy a jeho přiřazením k SoapEnum vlastnosti objektu SoapAttributes.SoapEnumAttribute Podrobnosti najdete v přehledu SoapAttributeOverrides třídy.

Chcete-li serializovat objekt jako kódovanou zprávu SOAP, musíte vytvořit XmlSerializer pomocí XmlTypeMapping vytvořené metody ImportTypeMapping SoapReflectionImporter třídy.

Další informace o používání atributů najdete v tématu Atributy.
