Limiting access to a public setter to specific objects (C#)

Question

I\'m trying to create a class (in C#) that serves as an environment for my application.

I\'m trying to make the class dynamic, and send it as a parameter to entities

Why not return clones of your protected objects instead of the actual objects? Solves the problem without adding any more complexity.

public class MyService
{
    private List _protectedObjects = new List();

    public MyObject GetItem(int id)
    {
        return (MyObject)_protectedObjects.First(i => i.Id == id).Clone();
    }
}

public class MyObject : ICloneable
{
     //[...]
     public object Clone()
     {
         return MemberwiseClone();
     }
}
