EventLogEntryCollection (Clase)

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 Entries de la clase EventLog es una colección de todas las entradas del registro de eventos.

Dado que las nuevas entradas se agregan al final de la lista, el recorrido paso a paso por la colección permite el acceso a las entradas creadas después de EventLogEntryCollection. Sin embargo, una vez examinada toda la lista, ésta no se actualiza con nuevas entradas.
