Esempio

Nell'esempio seguente viene creato un nuovo SoapAttributeAttribute oggetto utilizzato per eseguire l'override della serializzazione di un campo. Dopo aver creato un oggetto SoapAttributeAttribute e impostato le relative proprietà, l'oggetto viene impostato sulla SoapAttribute proprietà di un oggetto SoapAttributes. Viene SoapAttributes quindi aggiunto a un SoapAttributeOverrides oggetto utilizzato per creare un oggetto XmlSerializer.
