HttpApplication.LogRequest Evento

public:
 event EventHandler ^ LogRequest;

public event EventHandler LogRequest;

member this.LogRequest : EventHandler 

Public Custom Event LogRequest As EventHandler 

Nell'esempio seguente viene illustrato come fornire un gestore eventi per l'evento LogRequest . Il gestore eventi gestisce anche diversi altri eventi. Di conseguenza, le CurrentNotification proprietà e IsPostNotification vengono usate per determinare il codice da eseguire.

L'evento LogRequest viene generato anche se si verifica un errore. È possibile fornire un gestore eventi per l'evento LogRequest per fornire la registrazione personalizzata per la richiesta.

Per altre informazioni su come gestire gli eventi, vedere la gestione e generazione di eventi.

LogRequest è stato introdotto in .NET Framework versione 3.5. Per altre informazioni, vedere Versioni e dipendenze.
