Question

我在Visual Studio中学习Windows应用程序表单，我正在编写一个数字猜谜游戏，程序生成一个随机数。我把随机数生成器放在Button_Click方法中，我希望数字在程序启动时说同样的，但每次单击按钮时它都会改变。

public partial class myWindow : Form
{


    public myWindow()
    {
        InitializeComponent();
    }

    private void guessButton_Click(object sender, EventArgs e)
    {

            Random random = new Random();
            int roll = random.Next(0, 99);

我应该在哪里声明或放置随机数生成器和变量，以便它不会改变？

让它成为班级成员：

public partial class myWindow : Form
{
    private int _roll;
    private int _numGuesses;

    public Window()
    {
        InitializeComponent();

        Random random = new Random();
        _roll = random.Next(0, 99);
    }

    private void guessButton_Click(object sender, EventArgs e)
    {
        bool isGuessCorrect = // Set this however you need to

        if (isGuessCorrect)
        {
            // They got it right!
        }
        else
        {
            _numGuesses++;
            if (_numGuesses > 9)
            {
                // Tell them they failed
            }
            else
            {
                // Tell them they're wrong, but have 10 - _numGuesses guesses left
            }
        }
    }
}
