C# 使用数组随机播放

Question

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）从第一牌组开始，交替牌两者之间：

示例：Shuffle 之前-AS、2S、3S、...、QC、KC

1 次洗牌后： AD, AS, 2D, 2S, ..., KC, KH

20 次洗牌后： 3C、5D、7H、9S、质控

这是我的甲板构造器：

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]);
         } 

这是我到目前为止的主要内容：

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();
            }
        }

    } 

} 

}

关于如何做到这一点的任何想法？

Answer 1

这很简单：构造一个新数组，从位置 0 取出一张卡片，从 N/2 取出第二张，从 1 取出第三张，从 N/2+1 取出第四张，等等。
