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。
