c# - 变量不覆盖 C#

Question

我正在尝试设置一个“分数”变量，它会在我每次调用时添加一些分数时一直改变。然而，我的代码加了一些点，但如果我再次调用它，它会重新设置值并加起来。这意味着我想将一个点加到 0，它会打印 1，如果我想再次添加它，它将再次打印 1 个点。这是我的代码：

    class StatusManage
    {
        public int score;

        public void increase()
        {
            score++;
        }
    }

    class QuestionManage
    {
        StatusManage status = new StatusManage();
        public int limit = 4;

        public void choose()
        {
            Console.WriteLine("Your score: {0}", status.score);
            Questions q = new Questions();
            if (status.score >= limit)
            {
                Console.WriteLine("The end! Congratulation");
                status.score = 0;
            }
            switch (status.score)
            {
                case 0:
                    q.question1();
                    break;
                case 1:
                    q.question2();
                    break;
                case 2:
                    q.question3();
                    break;
            }
        }
        public void getAnswer(char correctAnswer)
        {
            Console.Write("Type your answer: ");
            ConsoleKeyInfo answer = Console.ReadKey();
            Console.WriteLine();
            if (char.ToUpper(answer.KeyChar) == correctAnswer)
            {
                Console.WriteLine("You are correct!");
                status.increase();
                choose();
            }
            else
            {
                Console.WriteLine("Incorrect answer, try it again...");
                getAnswer(correctAnswer);
            }
        }

    }

    }

这里是控制台中的结果：

谢谢你的帮助
