Question

我正在创建一个随机数猜测游戏，但我遇到了生成相同数字的生成器的问题，除非我关闭它并重新打开它。我有“你的号码太小/太大”。这样可行。但是我希望一旦点击按钮检查猜测就改变数字。什么是错的？

            Random random = new Random();
            randomNumber = random.Next(0, 10);

            }
            else if (Convert.ToInt32(textboxGuess.Text) < randomNumber)
            {
                MessageBox.Show("The Number Is Larger Than: " + textboxGuess.Text);

            }
            else if (Convert.ToInt32(textboxGuess.Text) > randomNumber)
            {
                MessageBox.Show("The Number Is Smaller Than: " + textboxGuess.Text);

            }

            else
            {
                MessageBox.Show("Your Guessed Incorrectly. The Random Number Is Not: " + textboxGuess.Text);
            }
        }
    }
}

Answer 1

在加载时生成第一个随机数，然后在用户猜到正确的数字时再次生成。

将您的Random对象作为字段（类成员）并在方法中使用它：

private void MakeNewRandomNumber()
{
    randomNumber = random.Next(0, 10);
}

在表单加载（当前正在生成数字的位置）调用此方法，并在验证猜测后再次在单击处理程序中调用此方法：

private void buttonCheckGuess_Click(object sender, EventArgs e)
{
    if (Convert.ToInt32(textboxGuess.Text) == randomNumber)
    {
        MessageBox.Show("Your Guessed Correctly! The Number Is: " + textboxGuess.Text);
        MakeNewRandomNumber();
    }

每次单击此按钮时，您需要创建一个随机数。

    int randomNumber;

    Random random;

    public Form1()
    {
        InitializeComponent();
        random = new Random();
    }

    private void Form1_Load(object sender, EventArgs e)
    {


    }

    private void buttonCheckGuess_Click(object sender, EventArgs e)
    {

        randomNumber = random.Next(0, 10);

        if (Convert.ToInt32(textboxGuess.Text) == randomNumber)
        {
            MessageBox.Show("Your Guessed Correctly! The Number Is: " + textboxGuess.Text);
        }
        else if (Convert.ToInt32(textboxGuess.Text) < randomNumber)
        {
            MessageBox.Show("The Number Is Larger Than: " + textboxGuess.Text);

        }
        else if (Convert.ToInt32(textboxGuess.Text) > randomNumber)
        {
            MessageBox.Show("The Number Is Smaller Than: " + textboxGuess.Text);

        }

        else
        {
            MessageBox.Show("Your Guessed Incorrectly. The Random Number Is Not: " + textboxGuess.Text);
        }
    }
}

随机数生成器，生成相同的数字
