Actualización: noviembre 2007

Define el tamaño y los enumeradores de una colección de instancias de EventLogEntry.

Espacio de nombres:  System.Diagnostics
Ensamblado:  System (en System.dll)

'Declaración
Public Class EventLogEntryCollection _
	Implements ICollection, IEnumerable
'Uso
Dim instance As EventLogEntryCollection
public class EventLogEntryCollection implements ICollection, 
	IEnumerable
public class EventLogEntryCollection implements ICollection, IEnumerable

Utilice la clase EventLogEntryCollection cuando lea las entradas asociadas a una instancia de EventLog. La propiedad EventLog de la clase Entries es una colección de todas las entradas del registro de eventos.

Dado que las nuevas entradas se agregan a la lista, el recorrido paso a paso por la colección permite el acceso a las entradas que se crearon después de EventLogEntryCollection. Sin embargo, después de examinar toda la lista, ésta no se actualiza con nuevas entradas.

El ejemplo siguiente muestra cómo obtener información del registro de eventos de un objeto EventLogEntryCollection.
