c# - 在 C# 中创建一个简单的工厂类

Question

我正在创建一个工厂类来简化创建另一个类的对象而不污染目标类的构造函数(我认为这就是工厂的用途)

这就是我目前所拥有的。

public class QFactory
{
    public Quiz.Question q(string text, string buttonname)
    {
        Quiz.Question question = new Quiz.Question();
        question.QuestionText = text;
        question.QuestionImage = buttonname;

        return question;
    }

    public Quiz.Answer a(string answerText, bool answerRight = false)
    {
        Quiz.Answer answer = new Quiz.Answer();
        answer.text = answerText;
        answer.correct = answerRight;
        return answer;
    }
}

为了使用它来创建 Quiz.Question 和 Quiz.Answer 对象，我必须按以下方式使用它。

Quiz.Question q = (new QFactory()).q("What is a tomato?","But_01_Idle");

Quiz.Answer a = (new QFactory()).a("fruit",true);
Quiz.Answer b = (new QFactory()).a("vegetable");
Quiz.Answer c = (new QFactory()).a("animal");

q.Answers = new List<Quiz.Answer>{a,b,c}; // add a,b,c answer to the question

我将如何更改 QFactory 类，使其用法像这样(单例？)？

Quiz.Question q = QFactory.q("what is a Tomato?","But_01_Idle");
