c# - WindowsFormsHost 错误 IsRedirected 未找到？

Question

我正在使用以下方法将 WINFORM 图表添加到我的 WPF 项目中

 System.Windows.Forms.Integration.WindowsFormsHost

我正在尝试解决“领空”呈现问题，其中主机始终呈现为窗口的最顶部元素。我正在使用的解决方法 sets

IsRedireced = "true"

当我将其插入我的 XMAL 代码时:

        <Grid x:Name="ssCurveChartGrid" Grid.Column="1" Margin="110,30,160,306" Grid.ColumnSpan="4" RenderTransformOrigin="0.479,0.186">
        <WindowsFormsHost IsRedirected =" "true">

        </WindowsFormsHost>
    </Grid>

或者我后面的代码:

System.Windows.Forms.Integration.WindowsFormsHost host =
            new System.Windows.Forms.Integration.WindowsFormsHost();

host.IsRedirected = "true";

我收到以下错误:

The property 'IsRedirected' was not found in type 'WindowsFormsHost'

截图如下:

谁能帮忙解释一下为什么会这样？我需要在我的 WINFORM 图表顶部显示一个元素!

谢谢

编辑:

代码取自 MSDN 站点:http://msdn.microsoft.com/en-us/library/ms752027.aspx

From MSDN: "By default, visible WindowsFormsHost elements are always drawn on top of other WPF elements, and they are unaffected by z-order. To enable z-ordering, set the IsRedirected property of the WindowsFormsHost to true and the CompositionMode property to Full or OutputOnly. To see the default z-order behavior"

“将以下 XAML 复制到 Grid 元素中。”

<!-- Z-order demonstration. -->
<Canvas Grid.Row="1" Grid.Column="1">
  <WindowsFormsHost Canvas.Top="20" Canvas.Left="20" Background="Yellow">
    <wf:Button Text="Windows Forms control" FlatStyle="Flat"/>
  </WindowsFormsHost>
  <Label Content="A WPF label" FontSize="24"/>
</Canvas>

Press F5 to build and run the application. The WindowsFormsHost element is painted over the label element.

“查看 IsRedirected 为真时的 z 顺序行为”

Replace the previous z-order example with the following XAML.
XAML

<!-- Z-order demonstration. -->
<Canvas Grid.Row="1" Grid.Column="1">
  <WindowsFormsHost IsRedirected="True" CompositionMode="Full" Canvas.Top="20" Canvas.Left="20" Background="Yellow">
    <wf:Button Text="Windows Forms control" FlatStyle="Flat"/>
  </WindowsFormsHost>
  <Label Content="A WPF label" FontSize="24"/>
</Canvas>

Press F5 to build and run the application. The label element is painted over the WindowsFormsHost element.
