Voorbeelden

Het volgende codevoorbeeld heeft twee delen. Het eerste is een fragment van een configuratiebestand waarmee ASP.NET statuscontrole een gebeurtenis kan gebruiken die is afgeleid van de klasse WebBaseErrorEvent. De tweede laat zien hoe u wordt afgeleid van de WebBaseErrorEvent klasse om de aangepaste gebeurtenis te maken.

Opmerkingen

ASP.NET statuscontrole maakt het productie- en operationele personeel mogelijk om geïmplementeerde webtoepassingen te beheren. De System.Web.Management naamruimte bevat de statusgebeurtenistypen die verantwoordelijk zijn voor het verpakken van statusgegevens van toepassingen en de providertypen die verantwoordelijk zijn voor het verwerken van deze gegevens. Het bevat ook ondersteunende typen die u helpen tijdens het beheer van statusevenementen.

De WebBaseErrorEvent klasse is de basisklasse voor de statuscontrolegebeurtenissen die foutvoorwaarden vertegenwoordigen. ASP.NET gebruikt WebBaseErrorEvent en de afgeleide typen om foutvoorwaarden aan te geven tijdens de levensduur van een webtoepassing.
