c# - 在 C# 中创建一副纸牌

Question

所以我正在尝试为我的一个编程类(class)创建一副纸牌。我从来没有真正做过这样的事情，如果我犯了一些愚蠢的错误，我深表歉意。我在 Visual Studio 中对此进行编码(根据类规则)。我正在尝试为我的 Deck 创建一个 Card 对象数组。我遇到的问题是，当我尝试打印数组时，我得到的只是 52 行 Card_Games.Card(命名空间是 Card_Games)。我在卡片类中做错了什么，没有正确地将卡片的值和花色分配给该卡片对象？

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        Deck.FillDeck();
        Deck.PrintDeck();
    }
}

class Card
{
    public int Value;
    public static string[] SuitsArray = new string[] {"Hearts", "Diamonds", "Clubs", "Spades"};
    public string Suit;

    public Card(int value, string suit)
    {
        Value = value;
        Suit = suit;
    }

    public Card(string input)
    {
        string tempValue = "";
        string suitSentence = "";
        switch (Value)
        {
            case 11:
                tempValue = "Jack";
                break;
            case 12:
                tempValue = "Queen";
                break;
            case 13:
                tempValue = "King";
                break;
            case 14:
                tempValue = "Ace";
                break;
            default:
                tempValue = Value.ToString();
                break;
        }
        switch (Suit)
        {
            case "Hearts":
                suitSentence = " of Hearts";
                break;
            case "Diamonds":
                suitSentence = " of Diamonds";
                break;
            case "Clubs":
                suitSentence = " of Clubs";
                break;
            case "Spades":
                suitSentence = " of Spades";
                break;
        }
        input = tempValue + suitSentence;
    }
}

class Deck
{
    public static Object[] deck = new Object[52];


    public static void FillDeck()
    {
        int index = 0;
        foreach (string suit in Card.SuitsArray)
        {
            for (int value = 2; value <= 14; value++)
            {
                Card card = new Card(value, suit);
                deck[index] = card;
                index++;
            }
        }
    }

    public static void PrintDeck()
    {
        for (int i=0; i<52; i++)
        {
            System.Diagnostics.Debug.WriteLine(deck[i]);
        }
    }
}

Answer 1

这是一个稍微优化过的版本。

我添加了 setter/getter 来提取命名值和全名，例如“黑桃 A”。并为套件使用 Enum。

然后我使用了一个带有模运算符 (%) 和 Math.Floor 的循环来填充卡片组。这就是枚举发挥作用的地方，因为使用枚举和整数很简单。

public class Card
{
    public enum Suites
    {
        Hearts = 0,
        Diamonds,
        Clubs,
        Spades
    }

    public int Value
    {
        get;
        set;
    }

    public Suites Suite
    {
        get;
        set;
    }

    //Used to get full name, also useful 
    //if you want to just get the named value
    public string NamedValue
    {
        get
        {
            string name = string.Empty;
            switch (Value)
            {
                case (14):
                    name = "Ace";
                    break;
                case (13):
                    name = "King";
                    break;
                case (12):
                    name = "Queen";
                    break;
                case (11):
                    name = "Jack";
                    break;
                default:
                    name = Value.ToString();
                    break;
            }

            return name;
        }
    }

    public string Name
    {
        get
        {
            return NamedValue + " of  " + Suite.ToString();
        }
    }

    public Card(int Value, Suites Suite)
    {
        this.Value = Value;
        this.Suite = Suite;
    }
}

public class Deck
{
    public List<Card> Cards = new List<Card>();
    public void FillDeck()
    {
        public void FillDeck()
        {
          //Can use a single loop utilising the mod operator % and Math.Floor
          //Using divition based on 13 cards in a suited
          for (int i = 0; i < 52; i++)
          {
             Card.Suites suite = (Card.Suites)(Math.Floor((decimal)i/13));
             //Add 2 to value as a cards start a 2
             int val = i%13 + 2;
             Cards.Add(new Card(val, suite));
          }
         }
    }

    public void PrintDeck()
    {
        foreach(Card card in this.Cards)
        {
            Console.WriteLine(card.Name);
        }
    }
}
