我很难理解退货声明究竟在做什么.例如,在这种方法中......

    public int GivePoints(int amount)
    {
        Points -= amount;
        return amount;
    }

即使我在返回后放置任何随机整数,GivePoints方法仍然完全相同.那么返回声明在做什么呢？

如何在C#中的控制台应用程序中分隔一组数字,而不是向用户询问每个单独的数字？例如,而不是这样做......

        double first, second, third, fourth;

        Console.Write("Please enter first digit: ");
        first = Convert.ToDouble(Console.ReadLine());
        Console.Write("Please enter second digit: ");
        second = Convert.ToDouble(Console.ReadLine());
        Console.Write("Please enter third digit: ");
        third = Convert.ToDouble(Console.ReadLine());
        Console.Write("Please enter fourth digit: ");
        fourth = Convert.ToDouble(Console.ReadLine());
