C# - 需要帮助生成随机数并在其他函数中多次使用相同的数字

Question

我正在尝试制作一个 psudo-Shut The Box 程序，该程序将掷骰子，用户可以选择覆盖对应于两个骰子的数字或骰子的总和。

到目前为止，除了一件事，似乎一切都运行良好。当我尝试单击任一用户输入选项的按钮时，很明显，由于选中了错误的复选框，它仍在生成随机数。

我怀疑这是我调用函数的方式造成的。有没有办法将骰子 1 和骰子 2 的随机值传递给在其他函数中调用时保持不变的值，同时在按下掷骰子按钮后能够再次随机生成？

    private  int firstDiceRandom()
    {
        Random diceOne = new Random();
        int oneDie = diceOne.Next(1, 7);
        System.Threading.Thread.Sleep(100);
        return oneDie;
    }

    // Set value of Random number to a value
    private int firstDiceValue()
    {
        int value = firstDiceRandom();
        return value;
    }

    // Random number for Dice Two
    private int secondDiceRandom()
    {
        Random diceTwo = new Random();
        int twoDie = diceTwo.Next(1, 7);
        return twoDie;
    }

    // Set value of Random number to a value
    private int secondDiceValue()
    {
        int value = secondDiceRandom();
        return value;
    }

    // Set value of Total random numbers
    private int totalDice()
    {
        int totalDice = firstDiceValue() + secondDiceValue();
        return totalDice;
    }

Answer 1

一种可以帮助您的解决方案是在此程序范围之外声明一个变量。换句话说，一个 public 变量。

public int RandomValueOne;

现在您要做的是将您的随机值存储在此 public 变量中。

    private int firstDiceValue()
{
    RandomValueOne = firstDiceRandom();
    return RandomValueOne;
}

现在您可以直接使用您的变量，而不必担心重新生成数字。调用你的函数 "FirstDiceValue" 一次并继续使用全局变量 isntead

C# - 需要帮助生成随机数并在其他函数中多次使用相同的数字

C# - Need help generating a random number and using the same number multiple times in other functions
