在WPF中显示两个多维数据集

Question

我想显示2个多维数据集，只需点击一下按钮。首先，第一个多维数据集会在删除后显示，并在C＃中的WPF应用程序中显示另一个多维数据集，所有操作都应该只需点击一下按钮就可以了？

试试那个PLZ

的Xaml

<Grid>
        <Button Content="Draw cube" Margin="167,260,161,0" Click="Button_Click"></Button>
        <Viewport3D Name="viewport3D1" Visibility="Hidden">
            <Viewport3D.Camera>
                <PerspectiveCamera x:Name="camMain" Position="6 5 6" LookDirection="-6 -5 -4">
                </PerspectiveCamera>
            </Viewport3D.Camera>
            <ModelVisual3D>
                <ModelVisual3D.Content>

背后的代码

您只需在按钮事件中使用计时器即可更改多维数据集的可见性

private Timer _timer;
public MainWindow()
{
    InitializeComponent();
}

private void Button_Click(object sender, RoutedEventArgs e)
{
    viewport3D1.Visibility = Visibility.Visible;
    _timer = new Timer(1000); // Set up the timer for 1 seconds
    _timer.Elapsed+=new ElapsedEventHandler(_timer_Elapsed);
    _timer.Enabled = true; // Enable it
}

public void _timer_Elapsed(object sender, ElapsedEventArgs e)
{
    Dispatcher.Invoke(new Action(() =>
    {
        viewport3D1.Visibility = Visibility.Hidden;
        viewport3D2.Visibility = Visibility.Visible;
    })); 
}
