Circular Reference On C# Properties

Question

May be this is a newbie question but here it is. I am developing a card game and i hava a class named Player ... Player has a property called Partner ( another Player ) and another property called Points.

public class Player
{ 
   public Player()
   {
   }
   public Player Partner { get; set; }

   private int points = 0;
   public int Points 
   { 
   get { return points;}
   set { 
       if (Partner != null) Partner.Points = value;
       points = value; 
       } // -> Here is the problem cause p1.Partner = p2 and p2.Partner = p1
   }

The question is : How is the most "elegant way" to set the Points property for a player and have its Partner points property set automatically ?

For instance:

Player p1 = new Player();
Player p2 = new Player();
p1.Partner = p2;
p2.Partner = p1;
p1.Points = 10;
int p = p2.Points

p should be equal to 10.

Thanks in advance , Marcelo Brazil< .

Answer 1

I think I would add a composite (thx @ noah) class "Team".

Team has properties for "Players" and "Points".

public class Team
    {
        public Player[] Players { get; set; } //or Player1 and Player2, depends
        public int Points { get; set; }
    }
}

Answer 2

set { 
    points = value; 
    if (Partner != null && Partner.Points != value)
    {
        Partner.Points = value;
    }
}

Will fix the circular reference, but having a Partnership object that they both refer to get the total points will be cleaner and allows each player to store the individual points they've scored too.
