下面以在Wpf中添加ZedGraph（用于创建任意数据的二维线型、条型、饼型图表的一个开源类库）控件，说明在WPF中使用Winform控件的方法。
1、 首先添加对如下两个dll文件的引用：WindowsFormsIntegration.dll，System.Windows.Forms.dll。
2、 由于要用到ZedGraph控件，所以也要添加对ZedGraph.dll的引用。
3、 在要使用WinForm控件的WPF窗体的XAML文件中添加如下内容（选中部分）：
即：
xmlns:wfi ="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration"
xmlns:wf ="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"
xmlns:zedgraph="clr-namespace:ZedGraph;assembly=ZedGraph"
4、 在WPF的容器控件内如Grid内首先要添加WinForm控件的宿主容器，用于衔接WPF和WinForm，
对应XAML如下：
<Grid>
<wfi:WindowsFormsHost Width="300" HorizontalAlignment="Right">
<wf:Label x:Name="lblName" Text="winForm控件在此” />
</wfi:WindowsFormsHost>
<wfi:WindowsFormsHost>
<wf:Button x:Name="nnn" Text="确定”/>
</wfi:WindowsFormsHost>
<wfi:WindowsFormsHost>
<zedgraph:ZedGraphControl x:Name="zedGraphControl" />
</wfi:WindowsFormsHost>
<Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="10,10,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
</Grid>
说明：<wfi:WindowsFormsHost></wfi:WindowsFormsHost>即为WinForm控件的宿主容器，每一个宿主容器只能放一个WinForm控件，如下例，放了三个WinForm控件，分别放在三个宿主容器里面，该容器可以设置属性来调整大小和布局。
注意：如上我添加的WinForm控件如在指定其Name时，必须加前缀x:，如添加Lable时<wf:Label x:Name="lblName" Text="我是WPF中的WinForm控件” />，否则后台代码无法访问。
5、 如果要在WPF后台代码中访问上面的Lable，可直接像在WinForm中使用一样。如在点击某一按钮时改变Lable内容，代码如下:lblName.Text=”内容已改变”;
6、 以使用WinForm控件ZedGraph绘制曲线为例，说明后台用法：
在后台用Using添加对System.Windows.Forms和ZedGraph和System.Drawing命名空间的引用，完整后台代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Windows.Forms;
using ZedGraph;
using System.Drawing;
namespace ZedGraphAtWpf2
{
/// <summary>
/// MainWindow.xaml 的交互逻辑
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void button1_Click(object sender, RoutedEventArgs e)
{
lblName.Text =”我是WinForm控件”;
}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
ZedGraph.GraphPane myPane = zedGraphControl.GraphPane;
myPane.Title.Text = "My Test Graph/n(For CodeProject Sample)";
myPane.XAxis.Title.Text = "My X Axis";
myPane.YAxis.Title.Text = "My Y Axis";
PointPairList list1 = new PointPairList();
PointPairList list2 = new PointPairList();
for (int i = 0; i < 36; i++)
{
double x = (double)i + 5;
double y1 = 1.5 + Math.Sin((double)i * 0.2);
double y2 = 3.0 * (1.5 + Math.Sin((double)i * 0.2));
list1.Add(x, y1);
list2.Add(x, y2);
}
// Generate a red curve with diamond
// symbols, and "Porsche" in the legend
LineItem myCurve = myPane.AddCurve("Porsche",
list1, System.Drawing.Color.Red, SymbolType.Diamond);
// Generate a blue curve with circle
// symbols, and "Piper" in the legend
LineItem myCurve2 = myPane.AddCurve("Piper",
list2, System.Drawing.Color.Blue, SymbolType.Circle);
zedGraphControl.AxisChange();
}
}
}
完整XAML如下：
<Window x:Class="ZedGraphAtWpf2.MainWindow"
xmlns:wfi ="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration"
xmlns:wf ="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"

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

Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded">
<Grid>
<wfi:WindowsFormsHost Width="300" HorizontalAlignment="Right">
<wf:Label x:Name="lblName" Text="WinForm控件在此” />
</wfi:WindowsFormsHost>
<wfi:WindowsFormsHost>
<wf:Button x:Name="nnn" Text="确定” />
</wfi:WindowsFormsHost>
<wfi:WindowsFormsHost>
<zedgraph:ZedGraphControl x:Name="zedGraphControl" />
</wfi:WindowsFormsHost>
<Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="10,10,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
</Grid>
</Window>
