Inizializza una nuova istanza della classe SoapElementAttribute.

Overload

SoapElementAttribute()	Inizializza una nuova istanza della classe SoapElementAttribute.
SoapElementAttribute(String)	Consente di inizializzare una nuova istanza della classe SoapElementAttribute e di specificare il nome dell'elemento XML.

SoapElementAttribute()

Inizializza una nuova istanza della classe SoapElementAttribute.

public SoapElementAttribute ();

Public Sub New ()

Esempio

Nell'esempio seguente viene serializzato un'istanza di una classe denominata contenente un campo denominato Transportation Vehicle. Viene SoapElementAttribute applicato al campo. Quando il campo viene serializzato, il nome dell'elemento XML è "Wheel" anziché "Vehicle". Il SerializeOverride metodo crea un SoapElementAttribute oggetto e imposta la SoapElement proprietà di un SoapAttributes oggetto SoapElementAttributesu . Viene SoapAttributes aggiunto a un SoapAttributeOverrides oggetto utilizzato per creare un XmlTypeMappingoggetto . Viene XmlSerializer costruito con , e viene nuovamente serializzata un'istanza XmlTypeMappingTransportation della classe. Poiché viene SoapElementAttribute usato per eseguire l'override della serializzazione, il nome dell'elemento XML generato è ora "Truck" anziché "Wheel".
