C# 使用用户输入来选择要从中随机打印元素的字符串数组

Question

我是编码新手，所以请原谅我的术语..

我正在尝试制作一个随机的英雄联盟皮肤选择器。我希望用户输入他们想要的冠军，在本例中我有 ahri 和 leeSin，然后通过用户输入，我希望它选择字符串数组并随机打印其中一个元素。我想我已经很接近了，但我不能将字符串与字符串 [] 一起使用。任何帮助将不胜感激。

namespace RandomLolChampSelector
{
    class Program
    {
        static void Main(string[] args)

        {
            string[] ahri = { "Academy", "Challenger", "Dynasty", "Foxfire", "Midnight", "Popstar" };
            string[] leeSin = { "Traditional", "Acolyte", "Dragon Fist", "Musy Thai", "Pool Party", "SKT T1", "Knockout" };

            // Creates title for application
            Console.WriteLine("Conor's Random League of Legends Skin Selector v0.1");
            Console.WriteLine(" ");
            Console.WriteLine(" ");

            Random rnd = new Random();

            Console.ForegroundColor = ConsoleColor.Gray;
            Console.WriteLine("What champion would you like to select a skin for?..    ");
            string champion = Console.ReadLine();

            foreach (string s in champion)
            {
                while (true)
                {
                    // Gets user to press a key to run the code
                    Console.Write("Press the 'enter' key for a random champion..     ");
                    string question = Console.ReadLine();

                    int randomNumber = rnd.Next(ahri.Length);
                    Console.WriteLine(ahri[randomNumber]);
                }
            }
        }
    }
}

一种方法是数组的数组。看看https://msdn.microsoft.com/en-us/library/aa288453(v=vs.71).aspx ，特别是他们谈论数组数组(锯齿状)的地方。

一种(可能)更直观的方法是数组字典。想想这样的事情:

Dictionary<string, string[]> myList = new Dictionary<string, string[]>();
myList.Add("ahri",new string[] { "Academy", "Challenger", "Dynasty", "Foxfire", "Midnight", "Popstar" });
//your other code
Console.WriteLine(myList[champion][randomNumber]);

考虑使用数组 myList[cham​​pion].Length 的长度作为随机数的边界，以避免出现越界错误。
