Question

我是编程c＃的新手。我试图编写一个在cmd中运行的简单程序。我认为它会随机创建一个noumber，用户会输入数字，他/她会尝试猜测随机创建的数字。程序会告诉你它是否低于或高于你输入的数字......我开始编程但是我遇到了问题...我无法比较用户输入的noumber和随机生成的数字。

这是代码......

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("Guess the number!");
        Random randomObject = new Random();
        int RandNoumber = randomObject.Next(9999) + 1;
        ConsoleKeyInfo keyinfo = Console.ReadKey();
        if (keyinfo < RandNoumber) //This is where I got an error msg
        {
        }
    }
}

感谢您的支持！

您可以使用Consol.ReadLine然后解析用户输入的值

static void Main(string[] args)
{
    Console.WriteLine("Guess the number!");
    Random randomObject = new Random();
    int RandNoumber = randomObject.Next(9999) + 1;

    int enteredNumber;
    while (true)
    {
        bool parsed = int.TryParse(Console.ReadLine(), out enteredNumber);

        if (parsed)
        {
            if (enteredNumber < RandNoumber)
            {
                Console.WriteLine("Wrong it's higher");
            }
            else if (enteredNumber > RandNoumber)
            {
                Console.WriteLine("Wrong it's lower");
            }
            else
            {
                Console.WriteLine("Good Job!");
                //Do victory dance
                return;
            }
        }
        else
        {
            Console.WriteLine("Please enter a number");
        }
    }
}

将ConsoleKeyInfo更改为int
