代表C#游戏卡类的最佳方法

问题描述

我使用Card类，其中包含2个枚举的属性(套房-心形菱形黑桃和球棒)，并且卡的值从2到A.并重写ToString()方法以返回类似Ah Ad等的内容.一切正常，但枚举值可以不是从数字开始的，因此我所列举的卡值看起来像x2，x3，x4……这并不漂亮.

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.

还需要一种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.

谁知道设计此类的最佳方法?

推荐答案

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

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 Jon Hanna的文章中采用了Card(string input)的结构答案.

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