Ejemplos

La siguiente TraceExtensionAttribute clase se deriva de SoapExtensionAttribute para admitir la aplicación del atributo a un método de servicio web XML o a un método de una clase de proxy de cliente de servicio web XML. Cuando se aplica a cualquiera de las dos, la TraceExtension extensión SOAP se ejecuta con el método .

// Create a SoapExtensionAttribute for a SOAP extension that can be
// applied to an XML Web service method.

public ref class TraceExtensionAttribute: public SoapExtensionAttribute

Comentarios

Los métodos de servicio web XML creados con ASP.NET se pueden configurar para ejecutarse con una extensión SOAP aplicando un atributo al método de servicio web XML. Cuando se agrega un atributo de extensión personalizado a un método de servicio web XML o a un método en una clase de proxy de cliente, ASP.NET invoca la extensión asociada en el momento adecuado. Un atributo de extensión es una clase de atributo personalizada que deriva de SoapExtensionAttribute. Los atributos derivados deben invalidar la ExtensionType propiedad para devolver el tipo de extensión asociado al atributo .
