C# Shuffle with Arrays

我的任务是创建一个洗牌方法，该方法接受洗牌次数的参数，但对于每次洗牌，1)将牌组(数组)分成两半，2)从第一副牌组开始，在两者之间交替使用牌组:

示例:Before Shuffle- AS, 2S, 3S，…、QC、KC

洗牌1次后:Ad, as, 2d, 2s，…， KC, KH

洗牌20次后:3C、5D、7H、9S、QC

这是我的桥牌构造函数:

class DeckOfCards  {
    private Card[] deck;  
    private int currentCard; 
    private const int NUMBER_OF_CARDS = 52; // constant number of Cards 
    private Random randomNumbers; 
    // constructor 
    public DeckOfCards() {
        string[] faces = { "A", "2", "3", "4",
                           "5", "6", "7", "8",
                           "9", "T", "J", "Q", "K" };
        string[] suits = { "S", "H", "D", "C" };
        deck = new Card[NUMBER_OF_CARDS]; 
        currentCard = 0; 
        randomNumbers = new Random(); 

        for (int count = 0; count < deck.Length; count++)
            deck[count] = new Card(faces[count % 13], suits[count / 13]);
         } 

这是我目前在main中的内容:

class Program  {
    static void Main(string[] args) {
        int numShuffles = 0;
        DeckOfCards myDeck = new DeckOfCards();
        for (int i = 0; i < 13; i++) {
            Console.WriteLine("{0} "+" {1} "+" {2} "+" {3}", myDeck.DealCard(), myDeck.DealCard(), myDeck.DealCard(), myDeck.DealCard());
        } 
        Console.ReadLine();
        Console.WriteLine("How Many Times Do You Want To Shuffle?");
        string index = Console.ReadLine();
        Console.WriteLine("You want to shuffle {0} times", index);
        Console.ReadLine();
        try {
            numShuffles = Convert.ToInt32(index);
            for (int i = 1; i <= numShuffles;  i++) {
              myDeck.Shuffle();
            }
        } catch (FormatException e) {
            Console.WriteLine("Input string is not a sequence of digits.");
        } catch (OverflowException e) {
            Console.WriteLine("The number cannot fit in an Int32.");
            Console.ReadLine();
        } finally {
            if (numShuffles < Int32.MaxValue) {
                Console.WriteLine("Preparing to shuffle " + numShuffles + " times");
                Console.ReadLine();

                    Console.WriteLine("{0} "+" {1} "+" {2} "+" {3} "+" {4}", myDeck.DealCard(), myDeck.DealCard(), myDeck.DealCard(), myDeck.DealCard(),
                        myDeck.DealCard());
                        Console.ReadLine();

            } else {
                Console.WriteLine("Your Input cannot be incremented beyond its current value");
                Console.ReadLine();
            }
        }
    } 
} 

}

有什么好主意吗?
