Ejemplos

El ForEachSMOEnumerator objeto se crea y hospeda en .ForEachEnumeratorHost En el ejemplo de código siguiente se muestra cómo crear un ForEachSMOEnumerator objeto dentro del objeto host.

            ForEachEnumeratorInfo info = null;  

            foreach (ForEachEnumeratorInfo enumInfo in infos)

                info = enumInfo;
