Definición

Se produce justo antes de que ASP.NET realice cualquier registro para la solicitud actual.Occurs just before ASP.NET performs any logging for the current request.

 event EventHandler ^ LogRequest;
public event EventHandler LogRequest;
member this.LogRequest : EventHandler 
Public Custom Event LogRequest As EventHandler 

Tipo de evento

EventHandler

Ejemplos

En el ejemplo siguiente se muestra cómo proporcionar un controlador de eventos para el LogRequest evento.The following example demonstrates how to provide an event handler for the LogRequest event. El controlador de eventos también controla otros eventos.The event handler also handles several other events. Por lo tanto, las CurrentNotification IsPostNotification propiedades y se usan para determinar qué código se debe ejecutar.Therefore, the CurrentNotification and IsPostNotification properties are used to determine what code to run.
