在WindowsFormsHost上添加WPF控件？

Question

如何在WindowsFormsHost上添加WPF控件（我已经知道，当我将Child添加到WFH时，它将成为一个单独的句柄）。 我尝试将其单独放置为StackPanel或Canvas，但似乎无法正常工作：

class CustomCanvas : Canvas{
public CustomCanvas(/*Some Width, Height, path values received*/){

WindowsFormsHost _AnimatedBckgr = new WindowsFormsHost()
            {
                Width = _wdt,
                Height = Container_Height,
                Margin = new Thickness(0,0,0,0),
                Child = new System.Windows.Forms.Panel()
            };

            ((System.Windows.Forms.Panel)_AnimatedBckgr.Child).Controls.Add(new System.Windows.Forms.PictureBox()
            {
                //Width = (int)_wdt, Height = (int)Container_Height,
                Dock = System.Windows.Forms.DockStyle.Fill,
                BackgroundImage = new System.Drawing.Bitmap(GifAnimatedFilePath),
                BackgroundImageLayout = System.Windows.Forms.ImageLayout.Stretch,
            });
//StackPanel or Canvas wndHost;
            wndHost = new StackPanel() { Width = _wdt, Height = Container_Height };
            wndHost.Children.Add(_AnimatedBckgr);

            Children.Add(wndHost); 
//Anything added in this canvas doesn't appears over the wndHost
            Children.Add(new Button(){ Content = "Hi" });

}
}

是否有其他方法可以在WindowsFormsHost上添加WPF控件，而无需使用骇人的透明Windows hack？ 谢谢。

在C＃程序代码中做了一些编写之后，我努力在主机上添加一个Host，以此类推。因此，我可以在覆盖WPF控件的WinForms控件上添加WPF控件...有些奇怪的东西，但是您可以自己尝试，如果在添加时未定义ElementHost或WindowsFormsHost大小，请注意.NET中存在sme错误。 例：

/*In a WPF Window, content container being a Canvas, adding a new WFH with
a `PicturBox()` on it. Then add it a DataGridView OVER this one, and then,
some `Label` over it*/

 public partial class MainWindow : Window
{
    public MainWindow()
    {
        Content = new Canvas();

        System.Windows.Forms.Integration.WindowsFormsHost _wndHost = new System.Windows.Forms.Integration.WindowsFormsHost()
        {
            Margin = new Thickness(0, 0, 0, 0),
            Width = 200,
            Height = 200,
            Child = new System.Windows.Forms.PictureBox()
            {
                BackgroundImage = new System.Drawing.Bitmap(System.IO.Directory.GetCurrentDirectory() + "\\f.jpg"),
                BackgroundImageLayout = System.Windows.Forms.ImageLayout.Stretch
            }
        };

        ((System.Windows.Forms.PictureBox)_wndHost.Child).Controls.Add(new System.Windows.Forms.DataGridView()
        {
            Width = 170, Height = 70,
            ColumnCount = 2, RowCount = 2
        });

        ((System.Windows.Forms.PictureBox)_wndHost.Child).Controls.Add(new System.Windows.Forms.Integration.ElementHost()
        {
            Width = 70, Height = 15,
            Child = new TextBlock()
            {
                Width = 10,
                Height = 10,
                Text = "First :O",
                Foreground = Brushes.Red,
                Background = Brushes.Transparent
            },
            BackColor = System.Drawing.Color.Transparent,
            Location = new System.Drawing.Point(10, 100)
        });

        ((System.Windows.Forms.PictureBox)_wndHost.Child).Controls.Add(new System.Windows.Forms.Integration.ElementHost()
        {
            Width = 70, Height = 15,
            Child = new TextBlock()
            {
                Width = 10,
                Height = 10,
                Text = "Second :O",
                Foreground = Brushes.Red,
                Background = Brushes.Transparent
            },
            BackColor = System.Drawing.Color.Transparent,
            Location = new System.Drawing.Point(10, 150)
        });

        ((Canvas)Content).Children.Add(_wndHost);


    }
}

好的，这更加接近了……将Windows窗体用户控件添加到您的项目中：

在该用户控件中添加您的图片：

现在回到XAML并添加WFH ...，添加刚刚创建的usercontrol的子级。

<Canvas>
  <WindowsForsHost HorizontalAlignment="Left" Height="34" VerticalAlignment="Top" Width="52">
    <local:UserControl1/>
  </WindowsformsHost>
  <Label Margin="0,35,-13,0">This is bill Clinton</Label>
</Canvas>

请注意，在标记中，标签的偏移量可以放置在画布上您想要的任何位置。

结果是这样，但它没有动画。
