我写了一个接受整数的函数。如果用户输入例如 -5，它不会崩溃，但它会将其转换为正 =-(

int getRandoms(int size, int upper, int lower)
{
    int randInt = 0;
    randInt = 1 + rand() % (upper -lower + 1);
    return randInt;
}

为了构建随机负整数，我应该在函数中更改什么？用户输入范围。

  int gameTurns = 12;
        do
        {               
            gameTurns -= 1;
            Console.WriteLine("     You have " + (gameTurns) + " attempts left.");
            Console.WriteLine();            
            Console.WriteLine();

            string userEnteredPassword = "";
            Console.WriteLine("Enter a password of 4 digits ");
            userEnteredPassword = Console.ReadLine();

           for (int i = 0; i < numbersToGuess.Length; i++)
            {
                numbersFromPlayer[i] = Convert.ToInt16(userEnteredPassword[i]);                    
                Console.WriteLine(numbersFromPlayer[i]);
            }

请注意,numbersToGuess声明如下:

 for (int i = 0; i <= 3; i++) 
        {
            numbersToGuess[i] = Convert.ToInt16(sequence.Next(9));
            Console.WriteLine(numbersToGuess[i]);
        }

当我使用值1,2,3,4运行我的代码时,它打印:49,50,51,52.
