Hämtar eller anger ett värde som anger om XmlSerializer serialiserar ett offentligt fält eller en egenskap som kodad SOAP XML.
public:
property bool SoapIgnore { bool get(); void set(bool value); };

member this.SoapIgnore : bool with get, set

Egenskapsvärde

XmlSerializer om får inte serialisera fältet eller egenskapen, annars . false
Exempel
I följande exempel serialiseras en klass med namnet Group. Serialiseringen av fälten GroupName och IgnoreThis och medlemmarna i GroupType uppräkningen åsidosättas.
CreateOverrideSerializer I metoden skapas en SoapAttributeOverrides och för varje åsidosatt medlem eller uppräkning skapas en SoapAttributes med lämplig egenskapsuppsättning och läggs till i SoapAttributeOverrides. En XmlTypeMapping skapas med hjälp av SoapAttributeOverrides, och som XmlTypeMapping används för att skapa XmlSerializer som åsidosätter standard serialiseringen.

Kommentarer
Som standard serialiseras alla offentliga fält och offentliga läs-/skrivegenskaper av XmlSerializer. Värdet för varje offentligt fält eller egenskap sparas alltså som ett XML-element eller XML-attribut i ett XML-dokument.
Om du vill åsidosätta standard serialiseringen för ett fält eller en egenskap skapar du en SoapAttributesoch anger dess SoapIgnore egenskap till true.
Add Använd metoden för att lägga till objektet i en SoapAttributeOverrides och ange vilken typ av objekt som innehåller fältet eller egenskapen som ska ignoreras och namnet på fältet eller egenskapen som ska ignoreras.
Om en SoapIgnoreAttribute tillämpas på ett fält eller en egenskap ignoreras fältet eller egenskapen. Du kan dock åsidosätta det beteendet genom att skapa en SoapAttributes, ange dess SoapIgnore egenskap till falseoch lägga till den i en SoapAttributeOverrides, ange typen av objekt som innehåller fältet eller egenskapen och namnet på fältet eller egenskapen.
