如何在WPF中嵌入Winform控件

当时把WPF的控件canvas的handle传给C++的项目去刷新图像的时候发现最后刷新的是整个WPF页面而不是控件所在的区域，还不知道有什么办法可以解决。

不过可以在WPF中嵌入WINFORM的图像控件PictureBox去做刷新。

嵌入方法：

1.在项目的References中加入WindowsFormsIntegration.dll和System.Windows.Form.dll

2.在页面的WPF中加入

[csharp] view plain copy

xmlns:wfi ="clr-namespace:System.Windows.Forms.Integrationassembly=WindowsFormsIntegration"

xmlns:wf ="clr-namespace:System.Windows.Formsassembly=System.Windows.Forms"

比如

[csharp] view plain copy

x:Class="WpfApplication1.MainWindow"

xmlns:wfi ="clr-namespace:System.Windows.Forms.Integrationassembly=WindowsFormsIntegration"

xmlns:wf ="clr-namespace:System.Windows.Formsassembly=System.Windows.Forms"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

title="MainWindow" Height="800" Width="1280" MouseMove="Window_MouseMove" MouseLeftButtonUp="Window_MouseLeftButtonUp" MouseDown="Window_MouseDown" MouseLeftButtonDown="Window_MouseLeftButtonDown">

然后我在Gridzhong 放下图像控件

[csharp] view plain copy

<Grid HorizontalAlignment="Left" Height="482" Margin="6,6,0,0" VerticalAlignment="Top" Width="737">

<wfi:WindowsFormsHost>

<wf:PictureBox x:Name="Cv_Main" Margin="0,0,0,0"></wf:PictureBox>

</wfi:WindowsFormsHost>

</Grid>

大功告成

功能实现主要分三步：

1、添加两个引用：WindowsFormsIntegration.dll（负责整合WPF和Windows）、System.Windows.Forms.

2、在 XAML文件中添加两个引用（粗体部分）：

<Window x:Class="CrossBowDemo.MainWindow"

xmlns:wfi ="clr-namespace:System.Windows.Forms.Integrationassembly=WindowsFormsIntegration"

xmlns:wf ="clr-namespace:System.Windows.Formsassembly=System.Windows.Forms"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

title="Hosting Windows Forms Control In WPF"

Height="300"

Width="650"

ResizeMode="NoResize"

Loaded="WindowLoadedHandler"

>

</Window>

3、在XAML编码区实现你想添加的控件：

原文添加的是DataGridView控<wfi:WindowsFormsHost>

<wf:DataGridView x:Name="Dg" Dock="Fill" SelectionMode="FullRowSelect">

</wf:DataGridView>

</wfi:WindowsFormsHost>
