Custom Parameter definition

Hi Guys,
I am trying to define a custom type to use it in between some component I am developing.I encountered a problem you may already know how to solve and can help.
my data type is a class like this:
 public class BaseProfile()
public BaseProfile(params object[] cellList)
 { this.ArticleNumber = (int)cellList[0];
   this.SystemName = (string)cellList[1];
    this.Material = (string)cellList[2];
    this.Shape = (string)cellList[3];
 ...}
then I define:
public class ProfileGHData : GH_Goo<BaseProfile>
and then:
public class ProfileGHParam : GH_Param<ProfileGHData>
here i define an ouput parameter which is a ProfileGHParam:
 pManager.AddParameter(new ProfileGHParam(), "blahblah", "bl", "Load Blahbalh", GH_ParamAccess.item);

in the SolveInstance It reads lines of a csv file split them with ; and then puts them in an array then make an instant of BaseProfile called profile1 and assign the array to profile1 like this:

BaseProfile profile1= new BaseProfile(cell1);

Now i need to somehow take profile1 and put it into a variable of type
ProfileGHParam. to use setdata() for it.but i can not find a way.
I defined an instant od ProfileGHParam and looked at methods available but did not get it . i thought cause it is  inherited from BaseProfile I may be able to cast or use a method to assign profile1 to it,also i tried to add a constructor to ProfileGHParam to get rid of BaseProfile but no luck.Probably I 've made it too long and complicated in the class definitions also and can be shorter.

Any idea and hint will be highly welcomed
  Thanks in advance
