在 C# 中表示游戏卡类的最佳方式 [英] Best way to represent game card class in C#

问题描述

我使用类 Card，它包含 2 个枚举属性(套房 - 红心钻石黑桃和俱乐部)和从 2 到 A 的卡值.并覆盖 ToString() 方法以返回类似 Ah Ad 等的内容.一切正常，但枚举值可以't以数字开头，所以我枚举的卡值看起来像x2，x3，x4……不漂亮.

I use class Card which contains 2 enumerated properties (suite - hearts diamonds spades and clubs) and card value from 2 to A. And overrides ToString() method to returns something like Ah Ad etc. All ok, but enum value can't starts with number, therefore my card value enumerated looks like x2, x3, x4 ... it is not beautiful.

还需要简单的方法来解析单个字符串中的几张卡片.

Also need simple approach to parse few cards from single string.

谁知道设计这个类的最佳方法?

推荐答案

您不能将 Jack、Queen、King 和 Ace 分别指定为 11、12、13 和 14 吗?它最终看起来像:

Couldn't you assign Jack, Queen, King, and Ace to be 11, 12, 13, and 14, respectively? It'd end up looking something like:

public class Card
{
    public int Value { get; private set; }
    public enum SuitType
    {
        Clubs, Spades, Hearts, Diamonds
    }
    public SuitType Suit { get; private set; }
    public Card(int value, SuitType suit)
    {
        Suit = suit;
        Value = value;
    }
    public Card(string input)
    {
        if (input == null || input.Length < 2 || input.Length > 2)
            throw new ArgumentException();
        switch (input[0])
        {
            case 'C': case 'c':
                Suit = SuitType.Clubs;
                break;
            case 'S': case 's':
                Suit = SuitType.Spades;
                break;
            case 'H': case 'h':
                Suit = SuitType.Hearts;
                break;
            case 'D': case 'd':
                Suit = SuitType.Diamonds;
                break;
            default:
                throw new ArgumentException();
        }
        int uncheckedValue = (int)input[1];
        if (uncheckedValue > 14 || uncheckedValue < 1)
            throw new ArgumentException();
        Value = uncheckedValue;
    }
    public string encode()
    {
        string encodedCard = "";
        switch (Suit)
        {
            case SuitType.Clubs:
                encodedCard += 'c';
                break;
            case SuitType.Spades:
                encodedCard += 's';
                break;
            case SuitType.Hearts:
                encodedCard += 'h';
                break;
            case SuitType.Diamonds:
                encodedCard += 'd';
                break;
        }
        encodedCard += (char) Value;
        return encodedCard;
    }
    public override string ToString()
    {
        string output = "";
        if (Value > 10)
        {
            switch (Value)
            {
                case 11:
                    output += "Jack";
                    break;
                case 12:
                    output += "Queen";
                    break;
                case 13:
                    output += "King";
                    break;
                case 14:
                    output += "Ace";
                    break;
            }
        }
        else
        {
            output += Value;
        }
        output += " of " + System.Enum.GetName(typeof(SuitType), Suit);
        return output;
    }
}

我添加了一些字符串功能.我从 乔恩·汉娜的回答.

I added some string functionality. I took structure of Card(string input) from Jon Hanna's answer.
