无法在循环中创建不同的随机数

Question

我是C#新手，在我创建的这个随机数猜谜游戏中，我很难理解哪里出错了。我试图在第30行的do time循环中添加一个random.next命令，当我运行程序时，它会说我的猜测太高或太低，我不明白出了什么问题。这是未完成的代码：

    static void Main(string[] args)
    {
        Random random = new Random();
        int numberToGuess = random.Next(100) + 1;
        int userGuess = 0;
        string name;

        Console.WriteLine("What is your name?");
        name = Convert.ToString(Console.ReadLine());

        Console.WriteLine("In this game you need to guess which number the computer has picked in the range of 1 to 100."
            + Environment.NewLine + "If the number you enter is too high or too low the program will display this, " +
            Environment.NewLine + "try to make the least amount of guesses as possible!" + Environment.NewLine 
            + "==========================================================================================================");

        do
        {

            do
            {
                Console.Write("Enter your guess: ");
                userGuess = Convert.ToInt32(Console.ReadLine());

                if (userGuess > numberToGuess)
                {
                    Console.WriteLine(userGuess + " is too high!");
                }
                else if (userGuess < numberToGuess)
                {
                    Console.WriteLine(userGuess + " is too low!");
                }
                else
                {
                    Console.WriteLine(userGuess + " SPOT ON! Congratulations.");
                }

                numberToGuess = random.Next(100) + 1;

            } while (userGuess != numberToGuess);

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


    }

如果我删除numberTo猜测=随机。下一个（100）1；代码工作正常，但重复相同的随机数。

请帮忙。

此方法将返回一个真正的随机数。

公共共享函数R的整数（最小值为整数，最大值为整数）作为整数暗淡兰德作为新系统。安全性。密码学。RNGCryptoServiceProvider暗淡缩放为Uintger=Uintger。MaxValue同时缩放=Uintger。MaxValue'获取四个随机字节。暗淡four_bytes作为字节（）=新字节（3）{}兰德。GetBytes（four_bytes）

            ' Convert that into an uint.
            scale = BitConverter.ToUInt32(four_bytes, 0)
        End While

        ' Add min to the scaled difference between max and min.
        Return CInt(min + (max - min) * (scale / CDbl(UInteger.MaxValue)))
    End Function

您的猜测范围非常高1到100，每次您都再次生成随机数。例如，只需减小您的随机生成器大小

 int numberToGuess = random.Next(5) + 1;

首先检查它是否工作良好，然后考虑扩展它。

调试您的应用程序替换

Console.Write("Enter your guess: ");

具有

Console.Write("Enter your guess (" + numberToGuess + "): ");

你会看到数字猜测每次都在变化。。。您应该注释该行，并仅使用生成的第一个随机数。
