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:WindowsFormsHost x: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：

<Window x: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>

            <Menu DockPanel.Dock="Top">

                <MenuItem Header="文件">

                    <MenuItem Header="打开">

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

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

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

                    </MenuItem>

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

                </MenuItem>

                <MenuItem Header="编辑">

                    <MenuItem Header="复制"></MenuItem>

                    <MenuItem Header="粘贴"></MenuItem>

                </MenuItem>

            </Menu>

            <ToolBar DockPanel.Dock="Top" Height="40">

                <Button>

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

                </Button>

                <Button>

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

                </Button>

                <Button>

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

                </Button>

            </ToolBar>

            <TabControl DockPanel.Dock="Left" >

                <TabItem Header="TabItem">

                    <Grid Background="#FFE5E5E5"/>

                </TabItem>

                <TabItem Header="TabItem">

                    <Grid Background="#FFE5E5E5"/>

                </TabItem>

            </TabControl>

            <Grid Height="Auto" Width="Auto"  Background="AliceBlue">

                <Grid.RowDefinitions>

                    <RowDefinition Height="Auto"></RowDefinition>

                    <RowDefinition></RowDefinition>

                </Grid.RowDefinitions>

                <Grid.ColumnDefinitions>

                    <ColumnDefinition></ColumnDefinition>

                    <ColumnDefinition></ColumnDefinition>

                </Grid.ColumnDefinitions>

                <local:TickerControl x: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:WindowsFormsHost x: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。
