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。
