    在.net3.0、3.5的WPF程序中虽然可以通过在References里添加对System.Windows.Forms库的引用访问2.0的控件，但是在WPF Xaml中却不能直使用2.0的控件，必须通过一个叫WindowsFormsHost的容器进行包装：

<Window x:Class="Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="HostingWfInWpf"
    >

  <Grid>
    <WindowsFormsHost Name="winFormsContainer">
    </WindowsFormsHost>
  </Grid>
</Window>

然后，你可以在后台代码中通过代码往host中添加控件：

System.Windows.Forms.Control ctrls = new System.Windows.Forms.Control()

winFormsContainer.Child = ctrls;

ctrls.Container.Add(new TextBox());
ctrls.Container.Add(new Label());

......

下面是MS的一个例子：

Xaml：

<Window x:Class="Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="HostingWfInWpf" Height="300" Width="300"
    Loaded="WindowLoaded"
    >
  <Grid Name="grid1">

    </Grid>
</Window>

back code：

using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Media;
using System.Windows.Shapes;

using System.Windows.Forms;

namespace HostingWfInWpf
...{   
    public partial class Window1 : Window
    ...{
        public Window1()
        ...{
            InitializeComponent();
        }

        private void WindowLoaded(object sender, RoutedEventArgs e) 
        ...{
            // Create the interop host control.
            System.Windows.Forms.Integration.WindowsFormsHost host =
                new System.Windows.Forms.Integration.WindowsFormsHost();

            // Create the MaskedTextBox control.
            MaskedTextBox mtbDate = new MaskedTextBox("00/00/0000");

            // Assign the MaskedTextBox control as the host control's child.
            host.Child = mtbDate;

            // Add the interop host control to the Grid
            // control's collection of child controls.
            this.grid1.Children.Add(host);
        }
    }
}

相反，要在Windows Forms中使用WPF控件，就要用到ElementHost 。你可以在Forms里面添加一个Panel，然后再在这个Panel中添加WPF控件。下面是MS的一个例子：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Windows;
using System.Windows.Forms;
using System.Windows.Controls;
using System.Windows.Forms.Integration;
using System.Windows.Media;

namespace WFHost
...{
    partial class Form1 : Form
    ...{
        private ElementHost ctrlHost;
        private MyControls.Page1 avAddressCtrl;
        System.Windows.FontWeight initFontWeight;
        double initFontSize;
        System.Windows.FontStyle initFontStyle;
        System.Windows.Media.SolidColorBrush initBackBrush;
        System.Windows.Media.SolidColorBrush initForeBrush;
        FontFamily initFontFamily;

        public Form1()
        ...{
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        ...{
            ctrlHost = new ElementHost();
            ctrlHost.Dock = DockStyle.Fill;
            panel1.Controls.Add(ctrlHost);
            avAddressCtrl = new MyControls.Page1();
            avAddressCtrl.InitializeComponent();
            ctrlHost.Child = avAddressCtrl;

            avAddressCtrl.OnButtonClick += 
                new MyControls.Page1.MyControlEventHandler(
                avAddressCtrl_OnButtonClick);
            avAddressCtrl.Loaded += new RoutedEventHandler(
                avAddressCtrl_Loaded);
        }

        void avAddressCtrl_Loaded(object sender, EventArgs e)
        ...{
            initBackBrush = (SolidColorBrush)avAddressCtrl.MyControl_Background;
            initForeBrush = avAddressCtrl.MyControl_Foreground;
            initFontFamily = avAddressCtrl.MyControl_FontFamily;
            initFontSize = avAddressCtrl.MyControl_FontSize;
            initFontWeight = avAddressCtrl.MyControl_FontWeight;
            initFontStyle = avAddressCtrl.MyControl_FontStyle;
        }

        void avAddressCtrl_OnButtonClick(
            object sender, 
            MyControls.MyControlEventArgs args)
        ...{
            if (args.IsOK)
            ...{
                lblAddress.Text = "Street Address: " + args.MyStreetAddress;
                lblCity.Text = "City: " + args.MyCity;
                lblName.Text = "Name: " + args.MyName;
                lblState.Text = "State: " + args.MyState;
                lblZip.Text = "Zip: " + args.MyZip;
            }
            else
            ...{
                lblAddress.Text = "Street Address: ";
                lblCity.Text = "City: ";
                lblName.Text = "Name: ";
                lblState.Text = "State: ";
                lblZip.Text = "Zip: ";
            }
        }

        private void radioBackgroundOriginal_CheckedChanged(object sender, EventArgs e)
        ...{
            avAddressCtrl.MyControl_Background = initBackBrush;
        }

        private void radioBackgroundLightGreen_CheckedChanged(object sender, EventArgs e)
        ...{
            avAddressCtrl.MyControl_Background = new SolidColorBrush(Colors.LightGreen);
        }

        private void radioBackgroundLightSalmon_CheckedChanged(object sender, EventArgs e)
        ...{
            avAddressCtrl.MyControl_Background = new SolidColorBrush(Colors.LightSalmon);
        }

        private void radioForegroundOriginal_CheckedChanged(object sender, EventArgs e)
        ...{
            avAddressCtrl.MyControl_Foreground = initForeBrush;
        }

        private void radioForegroundRed_CheckedChanged(object sender, EventArgs e)
        ...{
            avAddressCtrl.MyControl_Foreground = new System.Windows.Media.SolidColorBrush(Colors.Red);
        }

        private void radioForegroundYellow_CheckedChanged(object sender, EventArgs e)
        ...{
            avAddressCtrl.MyControl_Foreground = new System.Windows.Media.SolidColorBrush(Colors.Yellow);
        }

        private void radioFamilyOriginal_CheckedChanged(object sender, EventArgs e)
        ...{
            avAddressCtrl.MyControl_FontFamily = initFontFamily;
        }

        private void radioFamilyTimes_CheckedChanged(object sender, EventArgs e)
        ...{
            avAddressCtrl.MyControl_FontFamily = new FontFamily("Times New Roman");
        }

        private void radioFamilyWingDings_CheckedChanged(object sender, EventArgs e)
        ...{
            avAddressCtrl.MyControl_FontFamily = new FontFamily("WingDings");
