C#下WPF中调用WinForm控件

最近在C#下调用NPlot生成股票K线图，由于用的WPF框架，而NPlot是基于WinForm开发的。所以不能直接引用。具体做法如下：   NPlot源码Microsoft .NET Framework 4.5版

1、引入DLL

创建工程后需要引入WindowsFormsIntegration.dll和System.Windows.Forms.dll两个Dll。WindowsFormsIntegration.dll负责整合WPF和Windows。

2、在xaml中添加命名空间标签

xmlns:WinFormIntegration="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration"

3、添加宿主容器

<WinFormIntegration:WindowsFormsHostx:Name="winFormsHost"Grid.Row="1"Width="Auto"Grid.ColumnSpan="2">

     <!--在此添加WinForm控件-->

</WinFormIntegration:WindowsFormsHost>

本例完整的xaml文件：

<Windowx:Class="AxyDeal.MainWindow"

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

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

       Title="MainWindow"Height="600"Width="1080"

       xmlns:local="clr-namespace:AxyDeal.comcontrol"

        xmlns:WinFormIntegration="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration"

       >

   <Grid>

       <DockPanel>

           <MenuDockPanel.Dock="Top">

               <MenuItemHeader="文件">

                   <MenuItemHeader="打开">

                       <MenuItemHeader="1.txt"></MenuItem>

                       <MenuItemHeader="2.txt"></MenuItem>

                       <MenuItemHeader="3.txt"></MenuItem>

                   </MenuItem>

                   <MenuItemHeader="退出"Name="miExit"Click="miExit_Click"></MenuItem>

               </MenuItem>

               <MenuItemHeader="编辑">

                   <MenuItemHeader="复制"></MenuItem>

                   <MenuItemHeader="粘贴"></MenuItem>

               </MenuItem>

           </Menu>

           <ToolBarDockPanel.Dock="Top"Height="40">

               <Button>

                   <ImageSource="images/logo_email.png"></Image>

               </Button>

               <Button>

                   <ImageSource="images/logo_dropbox.png"></Image>

               </Button>

               <Button>

                   <ImageSource="images/logo_evernote.png"></Image>

               </Button>

           </ToolBar>

           <TabControlDockPanel.Dock="Left" >

               <TabItemHeader="TabItem">

                   <GridBackground="#FFE5E5E5"/>

               </TabItem>

               <TabItemHeader="TabItem">

                   <GridBackground="#FFE5E5E5"/>

               </TabItem>

           </TabControl>

           <GridHeight="Auto"Width="Auto" Background="AliceBlue">

               <Grid.RowDefinitions>

                   <RowDefinitionHeight="Auto"></RowDefinition>

                   <RowDefinition></RowDefinition>

               </Grid.RowDefinitions>

               <Grid.ColumnDefinitions>

                   <ColumnDefinition></ColumnDefinition>

                   <ColumnDefinition></ColumnDefinition>

               </Grid.ColumnDefinitions>

               <local:TickerControlx:Name="tickerControl"Grid.Row="0"Height="50"Grid.ColumnSpan="2"Grid.RowSpan="1"Width="686"VerticalAlignment="Top"HorizontalAlignment="Center"Visibility="Visible"Margin="1,0,0,0" ></local:TickerControl>

               <WinFormIntegration:WindowsFormsHostx:Name="winFormsHost"Grid.Row="1"Width="Auto"Grid.ColumnSpan="2">

                   <!--在此添加WinForm控件-->

               </WinFormIntegration:WindowsFormsHost>              

           </Grid>

       </DockPanel>

   </Grid>

</Window>

4、在代码中引入WinForm控件

这里声明了两个要引入的变量

//Form实例

private Form kLineForm = new Form();

//要引入的NPlot控件

private NPlot.Windows.PlotSurface2D KLinePS;

然后在MainWindow方法中添加：

//把Form添加的xaml中创建的宿主容器

this.winFormsHost.Child =this.kLineForm;

KLinePS =new NPlot.Windows.PlotSurface2D();

//把NPlot控件添加的Form中

this.kLineForm.Controls.Add(this.KLinePS);

至此可以在WPF中任意使用NPlot了。

使用NPlot是一款免费又开源的.Net平台下的图表控件，能做各种曲线图，柱状图，饼图，散点图，股票图等。
