'type' does not contain a definition for 'name' and no accessible extension method 'name' accepting a first argument of type 'type' could be found (are you missing a using directive or an assembly reference?).

This error occurs when you try to call a method or access a class member that does not exist.

espero su respuesta y muchas gracias!!!
