Deck.P​​rint仅显示2张黑桃已添加到牌组列表中

Question

因此，正如这个问题的标题所说，我的Deck.Print()仅显示已添加了2张黑桃。

我的理论是，由于某些原因，在Deck()中创建的卡片更改了卡片的花色和外观，因此它们坚持枚举的默认值（我假设默认值为0）在枚举中）。

从我的角度来看，它应该是创建卡，将Enum类型转换为I或F，然后将该卡添加到deck.list。为什么这不起作用？谢谢。

class Deck
{
    public List<Card> cards = new List<Card>();

    public Deck() // Generates all cards in the deck
    {
        for (int i = 0; i < 4; i++)
        {
            for (int f = 0; f < 13; f++)
            {
                Card card = new Card();
                card.Suit = (Suit)i;
                card.Face = (Face)f;
                cards.Add(card);
            }
        }
    }

    public void Print() // prints all cards in the deck , used for testing
    {
        foreach (var card in cards)
        {
            card.Print();
        }
    }
}
enum Suit
{
    Spades,
    Hearts,
    Diamonds,
    Clovers
}

enum Face
{
    Two,
    Three,
    Four,
    Five,
    Six,
    Seven,
    Eight,
    Nine,
    Ten,
    Jack,
    Queen,
    King,
    Ace
}

class Card
{
    private Suit suit;
    private Face face;

    public Suit Suit { get; set; }
    public Face Face { get; set; }

    public void Print()
    {
        Console.WriteLine("{0} of {1}", face, suit);
    }
}

Answer 1

因此，您的问题是，您正在使用Print方法读取（可能是） Backing Fields 的原始/可疑内容，而这又从未设置过。

如果您不需要这些字段，请像平常一样使用Auto Properties，并删除它们以免造成混淆

public Suit Suit { get; set; }

已修改

class Card
{
    // jsut delete these all together
    //private Suit suit; // you are printing this out and never changing it
    //private Face face; // you are printing this out and never changing it

    public Suit Suit { get; set; }
    public Face Face { get; set; }

    public void Print()
    {
      //  Console.WriteLine("{0} of {1}", face, suit);
      // print your actual properties not the backing fields that have never been set
      Console.WriteLine("{0} of {1}", Face, Suit);
    }
}
