C＃中的While循环问题

我试图编写一个while循环代码，我试图让用户输入一个1到50之间的数字并显示数字。到目前为止，如果我在50岁以内，我将打印出一条消息，如果我超过50岁，则将打印出另一条消息，但是如果用户想输入另一个数字，但我需要继续，但它会退出。

以下是我所拥有的：

class Program
{
    static void Main(string[] args)
    {
        const int from = 1;
        const int to = 50;

        int randomNumber = 50;
        int enteredNumber;

        Console.Write("The number is between 1 and 50.", from, to);
        while (true)
        {
            Console.Write("Enter a number: ");
            if (int.TryParse(Console.ReadLine(), out enteredNumber))
            {
                if (enteredNumber <= randomNumber)
                {
                    Console.WriteLine("You entered a number between 1 & 50");
                    break;
                }
                else
                {
                    if (enteredNumber > randomNumber)
                    {
                        Console.WriteLine("You didn't enter a number between 1 & 50.");
                        break;
                    }
                    else
                    {
                        Console.WriteLine("Press any key to exit.");
                        Console.ReadKey();
                    }
                }
            }
        }
    }
}

正如其他人所指出的那样，break它位于错误的位置。

看看这个。我清理它并添加了一些错误处理，现在允许用户通过输入“ Quit ”退出或按“ Enter ”继续。

class Program
{
    private static void Main(string[] args)
    {
        const int from = 1;
        const int to = 50;

        int randomNumber = 50;
        int enteredNumber;

        Console.Write("The number is between 1 and 50.", from, to);
        while (true)
        {
            Console.Write("Enter a number: ");
            if (int.TryParse(Console.ReadLine(), out enteredNumber))
            {
                if (enteredNumber <= randomNumber)
                {
                    Console.WriteLine("You entered a number between 1 & 50. Hit 'Enter' play again or enter 'Quit' to exit");
                    var answer = Console.ReadLine();
                    if (answer.ToLower() == "quit")
                    {
                        break;
                    }
                }
                else if (enteredNumber > randomNumber)
                {
                    Console.WriteLine("You didn't enter a number between 1 & 50. Hit 'Enter' play again or enter 'Quit' to exit");
                    var answer = Console.ReadLine();
                    if (answer.ToLower() == "quit")
                    {
                        break;
                    }

                }
            }
            else
            {
                Console.WriteLine("You didn't enter a number between 1 & 50. Hit 'Enter' play again or enter 'Quit' to exit");
                var answer = Console.ReadLine();
                if (answer.ToLower() == "quit")
                {
                    break;
                }
            }
        }
    }
}
