c# - Correcting implementation of a Factory Method with parameters -

i'm making solution program builds robots different types of parts(c#). in case have 2 types share attributes , both types of part inherit abstract class part.

until calling new actual button code in interface window , this.

if (type == acuatic)   part piecea = new acuaticpart(type,name,price,maxdepth); else   part pieceb = new terrestrialpart(type,name,price,terrain,maxtemp); 

i know totally wrong design , should implementing factory method. thing don't know if it's ok send parameters factory this:

in interface window:

part piece = _partfactory.createpart(type,name,price,maxdepth,terrain,maxtemp); 

in concrete factory:

public class concretepartfactory : partfactory {     public override part createpart(type,name,price,maxdepth,terrain,maxtemp)     {         part mypart = default(part);         switch (type)         {             case "actuatic":                 mypart = new aquaticpart(type,name,price,maxdepth);                 break;             case "terrestrial":                 mypart = new terrestrialpart(type,name,price,terrain,maxtemp);                 break;         }         return mypart;     } } 

the thing still have pass attributes , think isn't following open/closed principle, can fix this? thanks!

you may try overload factory method different signatures corresponding input arguments mentioned. in case, implement 2 methods, same name, having adequate , minimal set of arguments return objects of different classes. using approach may drop "type" well
