Question

我想要做的是我的tic tac toe主菜单的实时背景，它应该在任何按钮中随机放置X和Os所发生的事情就是程序刚刚冻结，当我尝试跟踪它时，调度程序中的代码永远不会得到执行

public partial class MainPage : PhoneApplicationPage
{
    Random random;
    private Button[] bts;
    private int counter;

    public MainPage()
    {
        InitializeComponent();
        counter = 0;
        bts = new[] { _1, _2, _3, _4, _5, _6, _7, _8, _9 };
    }

    private void Button_Click_1(object sender, RoutedEventArgs e)
    {
        NavigationService.Navigate(new Uri("/Page1.xaml", UriKind.Relative));
    }

    private void Button_Click_2(object sender, RoutedEventArgs e)
    {
        NavigationService.Navigate(new Uri("/Page3.xaml", UriKind.Relative));
    }

    private void About_Click(object sender, RoutedEventArgs e)
    {
        NavigationService.Navigate(new Uri("/Page4.xaml", UriKind.Relative));
    }

    private void form_Loaded(object sender, RoutedEventArgs e)
    {
        random = new Random();
        while (true)
        {
            Dispatcher.BeginInvoke(()=>
            {    
                bts[random.Next() % 9].Content = (counter % 2 == 0) ? "O" : "X";
                counter++;
            });
       }
    }
}

Answer 1

while (true) Dispatcher.BeginInvoke(...);

这是一个无限循环;它会永远冻结你的程序。（实际上，直到调度程序队列中的内存不足为止）

不要那样做。
