Question

我目前正在学校开展随机数字猜谜游戏。这只是我的第二周编程，所以这项任务对我来说至少可以说是挑战。我想我已经把一切都搞定了，除了我的循环必须在某个地方被破坏（我找不到它！）因为它从来没有找到正确的答案 - 只是说每个猜测都是错误的。我做了什么？？我希望你能帮助我:)非常感谢！

{
class Program
{
    public static int SelectedNumber = 0;
    public static Random ran = new Random();
    public static bool GameOver = false;
    public static int UserMaxValue = 0;



    static void Main(string[] args)
    {
        int UserNumber;
        SelectedNumber = ran.Next(0, UserMaxValue);

        do
        {
            Console.WriteLine("What is the maximum number you want to guess from?");
            UserMaxValue = Convert.ToInt32(Console.ReadLine());

            do
            {

                Console.WriteLine("Please make a guess between 1 and {0}", UserMaxValue);
                UserNumber = Convert.ToInt32(Console.ReadLine());
                GuessNumber(UserNumber);

            } while (GameOver == false);
        } while (GameOver == false);
    }

    public static void GuessNumber(int UserNumber)

    {
        int playagain = 0;

        if (UserNumber < SelectedNumber)
            Console.WriteLine("Wrong. Please try again.");
        else if (UserNumber > SelectedNumber)
            Console.WriteLine("Wrong.Please try again.");
        else
        {
            Console.WriteLine("Correct! The number is {0}. Again? (1 or 2)");
            playagain = Convert.ToInt32(Console.ReadLine());;

            while (playagain != 1 && playagain !=2)
            {
                Console.WriteLine("Invalid answer. Again? Y or N");
                playagain = Convert.ToInt32(Console.ReadLine());
            }

            if (playagain.Equals(2))
                GameOver = true;

            else
                SelectedNumber = ran.Next(0, UserMaxValue);
        }


    }
}


}

此：

SelectedNumber = ran.Next(0, UserMaxValue);

您运行此之前，提示用户填写UserMaxValue的值，以便您有效地进行

 SelectNumber = ran.Next(0, 0);

不是非常随机，当只有一个选项，并且该选择为0时......尤其是当您只允许1和稍后提供的最大值之间的猜测时。
