Heres我手上课的内容

>I am creating a blackjack game and so far I have made a card class, deck class, shoe class. The card class works the deck class works and the shoe class works but I am still working on my hand class and I need to call the SymbolToValue method to obtain the value for each card symbol and return the sum of the cards in the hand using th cardvalues array but I am not sure on how to do this

Any help would be appreciated

Heres what I have for my hand class

class Hand
    {
        const Int32 MAX_CARDS = 12;
        private Card[] _hand = new Card[MAX_CARDS];
        private Int32 _cardCount;
        public Hand()
        {
            _cardCount = 0;
        }
        public Int32 CardCount
        {
            get
            {
                
                return _cardCount;
            }
        }
        public void AddCard(Card card)
        {
            
            if (_cardCount < MAX_CARDS)
            {
                throw new Exception("Cannot of more than 12 cards in a hand");
            }
            else
            {
                 
                _cardCount++;
                card++;
                
            }
        }
        public Card GetCard(Int32 cardIndex)
        {
            if (cardIndex >= _cardCount)
            {
                throw new Exception("Invalid Entry");
            }
            else
            {
                return _hand[cardIndex];
            }
        }
        Int32[] cardValues = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10, 10 };
        String[] cardSymbols = { "A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K" };
        private Int32 SymbolToValue(String symbol)
        {
            Int32 index = 0;
            if (String.Equals(cardSymbols[index], symbol))
            {
                return index;
            }
            else
            {
                throw new Exception("Value Not In Table");
            }
        }
       public Int32 GetSum()
        {
            Int32 index = 0;
            String symbol = cardSymbols[index];
           Int32 index;
            SymbolToValue(symbol); 
        }
    }

推荐答案

您可以像这样实现SymbolToValue方法：

You can implement your SymbolToValue method like this:

private Int32 SymbolToValue(String symbol)
{
    int index = Array.IndexOf(cardSymbols, symbol);
    if (index != -1)
    {
        return cardValues[index];
    }
    else
    {
        throw new Exception("Value Not In Table");
    }
}

取得金额;我无法真正帮助你，因为我不知道Card类的内容，但使用SymbolToValue方法可能会更容易。

For taking the sum; I cannot really help you on that because I don't know the contents of the Card class, but it probably should be easier with the SymbolToValue method.
