Question

我正在进行C＃任务并且已经完成了很多工作，除了我无法弄清楚如何根据用户回答“是”或“否”重播循环。如果他们回答是，我希望循环重播，如果他们回答否，它将留下一个很好的告别消息。

这是我的代码（为简单起见删除了我的评论）：

Random randomNumber = new Random();

        int count = 0;
        int actualNumber = randomNumber.Next(1, 50);
        int userGuess = 0;
        bool correct = false;


        Console.WriteLine("In this program you will be prompted to guess a number between 1 and 50 \n\n" +
            "I'll help by saying if your guess is higher/lower than the actual number\n\n\n\n" +
            "I'm thinking of a number between 1 and 50, please enter your guess.\n\n");


        while (!correct)
            {
                count++;

                Console.Write("Guess: ");
                string input = Console.ReadLine();

                if (!int.TryParse(input, out userGuess))
                {
                    Console.WriteLine("That's not a number between 1 and 50, please try again.");
                    continue;
                }

                if (userGuess < actualNumber)
                {
                    Console.WriteLine("Sorry, the number is higher than that, keep guessing!");
                }
                else if (userGuess > actualNumber)
                {
                    Console.WriteLine("Sorry, the number is lower than that, keep guessing!.");
                }
                else
                {
                    correct = true;
                    Console.WriteLine("{0} is the right number! It took you         {1} times to guess", userGuess, count);
                }
            }

我无法弄清楚我是否应该使用另一个while语句或if / else或者使用它的内容和位置。我在这里搜索过，发现了不同语言的类似问题，但C＃没有。我将不胜感激任何帮助。谢谢！

您可以将代码置于do-while循环内。它会询问用户是否要重播？如果用户输入是，则游戏将重新开始。

Random randomNumber = new Random();

do
{  
    int actualNumber = randomNumber.Next(1, 50);
    int count = 0;
    int userGuess = 0;
    bool correct = false;

    Console.Clear();
    Console.WriteLine("In this program you will be prompted to guess a number between 1 and 50 \n\n" +
"I'll help by saying if your guess is higher/lower than the actual number\n\n\n\n" +
"I'm thinking of a number between 1 and 50, please enter your guess.\n\n");

    while (!correct)
    {
         // ...your code
    }

    Console.WriteLine("Do you want to replay?");
} while (Console.ReadLine().ToUpper() == "YES");

P.S： 如上所示，在循环外部初始化Random，否则会生成相同的数字。

C＃基于用户输入重复循环
