Esempio

Nell'esempio di codice seguente sono presenti due parti. Il primo è un estratto di un file di configurazione che consente ASP.NET monitoraggio dell'integrità per usare un evento derivato dalla WebBaseErrorEvent classe. Il secondo illustra come derivare dalla classe per creare l'evento WebBaseErrorEvent personalizzato.

Commenti

ASP.NET monitoraggio dell'integrità consente al personale di produzione e operazioni di gestire le applicazioni Web distribuite. Lo System.Web.Management spazio dei nomi contiene i tipi di evento di integrità responsabili della creazione di pacchetti di dati relativi allo stato dell'integrità dell'applicazione e i tipi di provider responsabili dell'elaborazione di questi dati. Contiene anche tipi di supporto che consentono durante la gestione degli eventi di integrità.

La WebBaseErrorEvent classe è la classe di base per gli eventi di monitoraggio dell'integrità che rappresentano le condizioni di errore. ASP.NET usa e i WebBaseErrorEvent relativi tipi derivati per indicare le condizioni di errore durante la durata di un'applicazione Web.
