带有随机问题的C#应用​​程序无法添加答案 [英] C# application with random questions can't add answers

问题描述

我有一个项目，我想用随机的问题和答案进行随机测验.我使用字典来完成此任务，并成功地提出了问题和答案，并随机显示了一个问题.

I have a project where I want to make a random quiz with random questions and answers. I used a dictionary to do this and I succeeded in making the questions and answers and in displaying a random one.

现在，我想为每个提出的问题添加具体答案.我想这也应该通过字典来完成，但是我不知道该如何做.

Now I want to add specific answers per question asked. I figured this should be done by a dictionary also but I don't know how to make this work.

我已经制作了随机生成器，问题和答案(tkey和tvalue)

I already made the random generator, the questions and answers (tkey and tvalue)

因此，现在我只需要添加一个部分，您可以为每个问题提供特定的答案，以及一种检测问题是对还是错的方法，这可以通过if和else语句来完成，但我的经验不足知道如何实现所有这些功能.

So now I only need to add a part where you have specific answers per questions and a way to detect if the questions are wrong or right, this can be done by a if and a else statement but I'm not experienced enough to know how to implement all these functions.

这就是我现在拥有的

class Program
{
    static public void Main()
    {
        //maak een dictionary aan
        Console.WriteLine("Quiz");

        Dictionary<int, string> Questions = new Dictionary<int, string>();

        //voeg vragen toe 
        //key koppelen aan vraag
        Questions.Add(11, "Vraag1?");
        Questions.Add(12, "Vraag2?");
        Questions.Add(13, "Vraag3?");
        Questions.Add(14, "Vraag4?");
        Questions.Add(15, "Vraag5?");

        Dictionary<int, string> answers = new Dictionary<int, string>();

        List<int> keylist = new List<int>(); // string naar int converten
        keylist = Questions.Keys.ToList();

        Random rand = new Random(); //maak random aan
        int countKeys = Questions.Keys.Count();
        int randomIndex = rand.Next(0, countKeys);

        Console.WriteLine(Questions.ElementAt(randomIndex).Key); //geef een random index en de gekoppelde key daaraan

        string input = Console.ReadLine();

        Console.WriteLine("You answered: " + input);

        Console.ReadKey();
    }
} 

有人可以通过告诉我/帮助我为这些问题添加具体答案的方式来帮助我吗?

Can someone help me by telling me / helping me make a way to add specific answers to these questions?

推荐答案

您可以使用 Dictionary< string，string> 将问题存储为键和答案为值

You can use a Dictionary<string, string> to store the questions as key and the answer as value

然后，获取密钥列表和随机播放，最后遍历该列表.

Then, get the list of keys and shuffle it, to finally iterate through that list.

在示例中(弄乱下面的代码):

private static Random rng = new Random();  

public static void Shuffle<T>(this IList<T> list)  
{  
    int n = list.Count;  
    while (n > 1)
    {  
        n--;  
        int k = rng.Next(n + 1);  
        T value = list[k];  
        list[k] = list[n];  
        list[n] = value;  
    }  
}

public static void Main(string[] args)
{
    var quizz = new Dictionary<string, string>
    {
        { "What is the answer to the Ultimate Question of Life, the Universe, and Everything ?", "42" },
        { "What is your name ?", "Sir Arthur, king of the Britons" },
        { "What is your quest ?", "To seek the Holy Grail" },
        { "What is the air-speed velocity of an unladen swallow?", "What do you mean ? An African or European swallow ?" }
    };
    var questions = quizz.Keys.ToList();
    questions.Shuffle();

    foreach (var question in questions)
    {
        Console.WriteLine(question);
        if (Console.ReadLine() != quizz[question])
        {
            Console.WriteLine("You failed");
            Console.ReadLine();
            break;
        }
        else
        {
            Console.WriteLine("Nice !");
        }
    }
}
