Comentarios

El resultado de una llamada a Union es un permiso que representa todas las operaciones representadas por el permiso actual y el permiso especificado. Cualquier petición que supere cualquiera de los permisos pasa su unión.

La unión de un permiso y null es el permiso que no nulles . La unión de un permiso y un subconjunto de ese permiso es el permiso que contiene el otro. Cualquier otra combinación produce una ArgumentException excepción.
