Comentarios

Use la EventLogEntryCollection clase al leer las entradas asociadas a una EventLog instancia de . La Entries propiedad de la EventLog clase es una colección de todas las entradas del registro de eventos.

Dado que las nuevas entradas se anexan a la lista existente, recorrer paso a paso la colección le permite acceder a las entradas que se crearon después de crear originalmente .EventLogEntryCollection Sin embargo, después de ver toda la lista, no se actualiza con nuevas entradas.

Propiedades

Count	Obtiene el número de entradas del registro de eventos (es decir, el número de elementos de la colección EventLogEntry).
Item[Int32]	Obtiene una entrada del registro de eventos, en función de un índice que empieza por 0 (cero).

Métodos

CopyTo(EventLogEntry[], Int32)	Copia los elementos de EventLogEntryCollection en una matriz de instancias EventLogEntry, a partir de un índice de la matriz determinado.
Equals(Object)	Determina si el objeto especificado es igual que el objeto actual. (Heredado de Object)
GetEnumerator()	Admite una iteración simple en el objeto EventLogEntryCollection.
GetHashCode()	Sirve como la función hash predeterminada. (Heredado de Object)
GetType()	Obtiene el Type de la instancia actual. (Heredado de Object)
MemberwiseClone()	Crea una copia superficial del Object actual. (Heredado de Object)
ToString()	Devuelve una cadena que representa el objeto actual. (Heredado de Object)

Implementaciones de interfaz explícitas

ICollection.CopyTo(Array, Int32)	Copia los elementos de la colección en un objeto Array, empezando por un índice determinado de Array.
ICollection.IsSynchronized	Obtiene un valor que indica si el acceso a EventLogEntryCollection está sincronizado (es seguro para subprocesos).
ICollection.SyncRoot	Obtiene un objeto que puede utilizarse para sincronizar el acceso al objeto EventLogEntryCollection.
