I am learning delegates.I am very curious to apply delegates to the following chain-of-responsibility pattern.

Kindly help me the way to apply delegates to the following piece.

Thanks in advance.Thanks for your effort.

#region Chain of Responsibility Pattern

        public abstract void HandlePlayer(Player _player);

        {
            _Successor = _handler;
        }
    }

    public class Employee : PlayerHandler
    {
        public override void HandlePlayer(Player _player)
        {
            if (_player.Score <= 100)
            {
                MessageBox.Show(string.Format("{0} is greeted 
                                by Employee", _player.Name));
            }
            else
            {
                _Successor.HandlePlayer(_player);
            }
        }
    }

    public class Supervisor : PlayerHandler

            }
        }
    }

                                 greeted by Manager", _player.Name));

            else
            {
                MessageBox.Show(string.Format("{0} got low score",
