还原后未正确显示C＃WPF窗口

标签： c# wpf resize

我有一个非常通用的WPF窗口，它开始最大化。当此窗口最小化到任务栏，然后恢复窗口不再填充屏幕。它显示了右侧桌面的一小部分。 Windows仍然认为它是最大化的，当设置为正常，然后再次最大化它看起来应该再次最小化。

    public partial class MainWindow : Window
{

    public MainWindow()
    {
        InitializeComponent();
        this.MaxHeight = SystemParameters.MaximizedPrimaryScreenHeight;
        this.MaxWidth = SystemParameters.MaximizedPrimaryScreenWidth;
    }

    private void ExitBtn_Click(object sender, MouseButtonEventArgs e)
    {
        this.Close();
    }
    private void MaxBtn_Click(object sender, MouseButtonEventArgs e)
    {
        this.WindowState = WindowState.Maximized;
        //Application.Current.MainWindow.WindowState = WindowState.Maximized;
        resizeBtn.Visibility = Visibility.Visible;
        maximizeBtn.Visibility = Visibility.Hidden;
    }
    private void ResBtn_Click(object sender, MouseButtonEventArgs e)
    {
        this.WindowState = WindowState.Normal;
        resizeBtn.Visibility = Visibility.Hidden;
        maximizeBtn.Visibility = Visibility.Visible;
    }
    private void MinBtn_Click(object sender, MouseButtonEventArgs e)
    {
        this.WindowState = WindowState.Minimized;
    }
    private void TitleBar_DblClick(object sender, MouseButtonEventArgs e)
    {
        if (this.WindowState == WindowState.Normal){ this.WindowState = WindowState.Maximized; return; }
        if (this.WindowState == WindowState.Maximized) { this.WindowState = WindowState.Normal; return; }
    }
}

你的想法？ UPDATE：

似乎与can resize属性有关。如果我把它设置为ca最小化就可以了。使用grip调整大小或调整大小会导致窗口在最小化到任务栏后更改大小。
