Question

let say i have following class:

class Shape
{
    public int widht;

    public List<Point> points;
}

and in class Point i want to use this widht property from class Shape, so if “point” belong to that list i wish to have possibility to use “container” properties. I also want to serialize then class Shape so I don’t think i can use constructor with parameters.

Edit:
I will say how it looks like in my app:
i have class Device

class Device
{
string connection;
List<Task> tasks;
}

and Task

class Task
{
  void DoTask()
  {
     and here i need the connection
  }
}

so i just like to do it then foreach(task in task) task.DoTask() but i have to pass additional “this” like task.DoTask(this) or the connection where i think that i should have acces of my container if it allows me.

Answer 1

There’s no general concept of the “owner” of an object. After all, the same Point reference could appear in several places. The desire to do this usually indicates a design smell. If you need to give the Point object more information, that’s presumably when you’re doing something with it – so pass that information to the appropriate method.
