Remove duplicated code - using Action

Question

Hi

I have the following code which obviously has some duplication. I'm sure this could be removed using a delegate or Action but can't quite grasp it.

anyone got any ideas?

public void DealStartingCards()
        {
            for (int i = 0; i < 3; i++)
            {
                foreach (var player in Players)
                {
                    if (player.Hand.FaceDownCards.Count < 3)
                    {
                        if (Deck.Count > 0) 
                        player.Hand.FaceDownCards.Add(Deck.TakeTopCard());
                    }
                }
            }

            for (int i = 0; i < 3; i++)
            {
                foreach (var player in Players)
                {
                    if (player.Hand.FaceUpCards.Count < 3)
                    {
                        if (Deck.Count > 0) 
                        player.Hand.FaceUpCards.Add(Deck.TakeTopCard());
                    }
                }
            }

            for (int i = 0; i < 3; i++)
            {
                foreach (var player in Players)
                {
                    if (player.Hand.InHandCards.Count < 3)
                    {
                        if (Deck.Count > 0) 
                        player.Hand.InHandCards.Add(Deck.TakeTopCard());
                    }
                }
            }
        }

InHandCards, FaceUpCards and FaceDownCards are all of type List<Card>

Taking Oskar's solution and changing it slightly:

private void DealCards(Func<Hand, List<Card>> handProjection)
{
    for (int i = 0; i < 3; i++)
    {
        foreach (var player in Players)
        {
            List<Card> cards = handProjection(player.Hand);
            if (cards.Count < 3)
            {
                if (Deck.Count > 0) 
                {
                    cards.Add(Deck.TakeTopCard());
                }
            }
        }
    }
}

public void DealStartingCards()
{
    DealCards(hand => hand.FaceDownCards);
    DealCards(hand => hand.FaceUpCards);
    DealCards(hand => hand.InHandCards);
}

(That's assuming the type of player.Hand is Hand - adjust accordingly otherwise, of course.)
