Comentarios

Aunque la OutArgs propiedad es redundante, ya que se puede lograr la misma funcionalidad a través del campo y GetOutArg el OutArgCount método, puede haber optimización del rendimiento disponible si el implementador entiende cuándo se recuperarán todos los argumentos.

Advertencia

Si Exception no nulles , se produce una System.IndexOutOfRangeException excepción cuando OutArgs se tiene acceso a ella.
