WPF - 从第一个窗口控制第二个窗口

Question

WPF - 从 Window1 我试图最大化以前最小化的 Window2。

这就是我打开 Window2 的方式（我希望使用相同的按钮来最大化它）

 public partial class Window1 : Window
{

    private bool SecondWindowOpen = false;

    public Window1()
    {
        InitializeComponent();
    }

    private void OpenSecondWindow_Click(object sender, RoutedEventArgs e)
    {
        if (SecondWindowOpen == false)
        {
            new Window2().Visibility = Visibility.Visible;
            this.SecondWindowOpen = true;

        }

        else
        {


        }
    }
}

Window2 有 2 个按钮，一个是最小化 Window2，另一个是关闭它。

public partial class Window2 : Window
{
    public Window2()
    {
        InitializeComponent();
    }

    private void btnMinimize_Click(object sender, RoutedEventArgs e)
    {
        this.WindowState = WindowState.Minimized;
    }

    private void btnClose_Click(object sender, RoutedEventArgs e)
    {
        Close();
    }
}

所以在打开 Window2 之后，我点击了 btnMinimize。现在我回到 Window1 并想单击 OpenSecondWindow 并将 Window2 返回到其原始位置。我认为这是一个语法问题，但我找不到任何示例。

谢谢

public partial class Window1 : Window
{

    private bool SecondWindowOpen = false;
    private Window2 window2;

    public Window1()
    {
        InitializeComponent();
    }

    private void OpenSecondWindow_Click(object sender, RoutedEventArgs e)
    {
        if (SecondWindowOpen == false)
        {
            window2 = new Window2();
            window2.Visibility = Visibility.Visible;
            this.SecondWindowOpen = true;
        }
        else
        {
            //do whatever you want with window2, like window2.Close();
            //or window2.Visibility = Visibility.Hidden;
        }
    }
}
