How do I create a winner in a game of BlackJack?

Question

In my c# we are building a blackjack game with classes. I have card.cs hand.cs and deck.cs which I'm posting with this. I am trying to put the game together and I cannot figure out the getWinner() method or how to code and show a winner. My code for my hand looks correct as far as I can tell- except when I first run the game it does not add and show the total of the two cards so I am starting there, then working on the winner- Can I create a winner in the Hand class? I was thinking it would be better on the Form.cs?

 class Hand
{
    private List<Card> listOfCards = new List<Card>();

    public int cardCount()
    {
        return listOfCards.Count();
    }

    public void addCard(Card card)
    {
        listOfCards.Add(card);
    }
    private void clearHand()
    {
        listOfCards.Clear();
    }
    public Card getCardAtIndex(int index)
    {
        Card card = new Card();
        if(index < listOfCards.Count)
        {
            card = listOfCards[index];
        }
        return card;
    }
    public int getAllCardsTotal()
    {
        int total = 0;
        int aceCount = 0;

        foreach(Card card in listOfCards)
        {
            if (card.getBlackJackValue() == 1)
                aceCount++;

            total = total + card.getBlackJackValue();
        }
        //See if we need to use the Ace as a 1 or 11
        if(aceCount > 0)
        {
            //Dealer stays 17-21 or can be player
            if (total >= 7 && total <= 11)
                total = total + 10;
        }
        return total;
    }
   
}

}

 class Deck
{
    private List<Card> listOfCards = new List<Card>();

    public Deck()
    {
        listOfCards.Clear();
        loadDeck();
    }
    public int cardCount()
    {
        return listOfCards.Count();
    }
   
    public Card drawCard()
    {
        Card card = new Card();

        //get random card from deck
        int cardCount = listOfCards.Count;

        Random random = new Random(Guid.NewGuid().GetHashCode());
        int cardIndex = random.Next(0, cardCount);

        card = listOfCards[cardIndex]; //Get a copy of the card
        listOfCards.RemoveAt(cardIndex); // This removes the card

        return card;
    }
    private void loadDeck()
    {
        //load in order A-KClubs- Diamonds - Hearts - Spades
        int imageIndex = 0;
        for(int rank = 1; rank <=13; rank++)
        {
            Card card = new Card(rank, Card.SuitType.Clubs, imageIndex);
            listOfCards.Add(card);
            imageIndex++; //increment each time we add a card

            card = new Card(rank, Card.SuitType.Diamonds, imageIndex);
            listOfCards.Add(card);
            imageIndex++; //increment each time we add a card

            card = new Card(rank, Card.SuitType.Hearts, imageIndex);
            listOfCards.Add(card);
            imageIndex++; //increment each time we add a card

            card = new Card(rank, Card.SuitType.Spades, imageIndex);
            listOfCards.Add(card);
            imageIndex++; //increment each time we add a card
        }
    }
}

}

class Card
{
    public enum SuitType { Clubs, Diamonds, Hearts, Spades}

    private int rank;
    private SuitType suit;
    private int blackJackValue;
    private int imageIndex;

    
    public SuitType Suit { get => suit; set => suit = value; }
    public int ImageIndex { get => imageIndex; set => imageIndex = value; }
    

    public Card(int rank, SuitType suit, int blackJackValue, int imageIndex)
    {
        this.rank = rank;
        this.suit = suit;
        this.imageIndex = imageIndex;
    }
    public Card()
    {

    }
    public Card(int rank, SuitType suit, int imageIndex)
    {
        this.rank = rank;
        this.Suit = suit;
        this.ImageIndex = imageIndex;
    }
    public int getBlackJackValue()
    {
        int blackJackValue = 0;

        if (rank > 9)
            blackJackValue = 10;
        
        else
            blackJackValue = rank;

        return blackJackValue;
    }
    public override string ToString()
    {
        String cardName = "";
        string cardRank = "";
        //Display a string of ace of clubs or 3 of diamonds
        if (rank == 13)
            cardRank = "King";
        else if (rank == 12)
            cardRank = "Queen";
        else if (rank == 11)
            cardRank = "Jack";
        else if (rank == 1)
            cardRank = "Ace";

        cardName = cardRank + "of" + suit.ToString();
        return cardName;
    }
}

}

And the form1.cs so far is:

    int totalGames = 0;
