I take it that you mean that you want to pass multiple pids, pnames and so on

One way to do it is to define a class holding the individual values, something like

C#

public class myparam {
   public string pid { get; set; }
   public string pname { get; set; }
   public string cid { get; set; }
   public string pcost { get; set; }
}

And then pass the objects in a list. So the definition for the Form2 constructor could be

C#

public Form2(System.Collections.Generic.List<myparam> listofparams) { ...
