Ejemplos

En el ejemplo de código siguiente se muestra cómo implementar un evento personalizado que usa el WebRequestInformation tipo .

También se muestra un extracto del archivo de configuración que permite ASP.NET usar este evento personalizado.

Asegúrese de que el evento personalizado se genera en el momento adecuado, es decir, cuando se genere el evento de mantenimiento del sistema equivalente que reemplace.

Comentarios

ASP.NET supervisión de estado permite al personal de producción y operaciones administrar las aplicaciones web implementadas. El System.Web.Management espacio de nombres contiene los tipos de eventos de mantenimiento responsables de empaquetar los datos de estado de mantenimiento de la aplicación y los tipos de proveedor responsables de procesar estos datos. También contiene tipos auxiliares que ayudan durante la administración de eventos de mantenimiento.

Las instancias de la WebRequestInformation clase contienen información que se obtiene mediante los WebRequestEventtipos , WebAuditEvent, WebErrorEvento WebRequestErrorEvent .

La aplicación necesita los permisos adecuados para acceder a la información protegida proporcionada por este tipo.
