从带字母和数字的字符串转换成c#如何读取、分离和放入数组

Question

我需要写一个程序，从一个用户确定的文件，我需要找出哪个扑克手类型是输入到程序中。我有一个地方，我可以在手中计算每一套花色的数量，但我想不出一种方法来找到纸牌的数量，它可以是两位数。如果它在数组中，那会更好，但我现在专注于将它放入字符串中。我主要是想计算每一张牌的值，这样我就可以得到每一手的if条件语句，以找到输入的手与假设的手相匹配。

每个手中的卡片的布局类似于以下文件标题: Flush.txt文件内容:C6C9C10C11C12

这就是我现在拥有的所有程序代码

尝尝这个

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string input = "C 6 C 9 C 10 C 11 C 12";
            string[] array = input.Split(new char[] {' '}, StringSplitOptions.RemoveEmptyEntries);
            for (int i = 0; i < 10; i += 2)
            {
                string suit = array[i];
                string rank = array[i + 1];

                Console.WriteLine("Card {0} , Suit : {1}, Rank : {2}" , i/2, suit, rank);
            }
            Console.ReadLine();
        }
    }
}

Answer 2

正如其他人已经建议的那样，最好使用更灵活的格式，如XML和JSON，但如果您坚持使用这种格式：

您可以按空格拆分输入，并以两个一组的方式读取数据：

var split = fileContent.Split(' ');
var cards = new List<KeyValuePair<string, int>>();
for (var i = 0; i < split.Length; i += 2)
{
    var suit = split[i];
    var digits = int.Parse(split[i + 1]);
    cards.Add(new KeyValuePair<string, int>(suit, digits));
}
// TODO: read the input from cards list

这里定义的纸牌列表由KeyValuePairs组成，其中关键是花色(例如"C")，值是数字(例如9)

Answer 3

首先，我建议您使用容器来存放纸牌套装。List<int>就可以了，但您可能需要更多，这取决于您的需要(Dict？class?)。我不认为这个解决方案是理想的，而且没有错误检查，但它采用了您在示例文件中显示的布局。

var clubs = new List<int>();
var hearts = new List<int>();
var diamonds = new List<int>();
var spades = new List<int>();

然后使用与下面显示的代码片段类似的代码来解析您的套装。

var parts = fileContent.Split(' ');

for (int i = 0; i < parts.Length; i+=2)
{
    if (parts[i] == "C")
    {
        clubs.Add(Int32.Parse(parts[i+1]));
    }
}

完整程序如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Poker
{
    class Program
    {

        static void Main(string[] args)
        {
            var clubs = new List<int>();
            var hearts = new List<int>();
            var diamonds = new List<int>();
            var spades = new List<int>();

            var fileContent = "C 6 C 9 C 10 C 11 C 12";

            var parts = fileContent.Split(' ');

            for (int i = 0; i < parts.Length; i += 2)
            {
                switch (parts[i])
                {
                    case "C": clubs.Add(Int32.Parse(parts[i + 1])); break;
                    case "H": hearts.Add(Int32.Parse(parts[i + 1])); break;
                    case "D": diamonds.Add(Int32.Parse(parts[i + 1])); break;
                    case "S": spades.Add(Int32.Parse(parts[i + 1])); break;
                    default:
                        break;
                }
            }

            Console.WriteLine("Clubs: {0}", string.Join(" ", clubs));
            Console.WriteLine("Hearts: {0}", string.Join(" ", hearts));
            Console.WriteLine("Diamonds: {0}", string.Join(" ", diamonds));
            Console.WriteLine("Spades: {0}", string.Join(" ", spades));

            Console.ReadLine();
        }
    }
}
