最近一段时间，由于新项目的需要，实验了一下，在WPF Application中打开网页的方法，现总结如下：
本人一共实验过4种方法：
第一种方法：使用框架提供的空间WebBrowser（详见http://msdn.microsoft.com/en-us/library/system.windows.controls.webbrowser.aspx）来实验网页的载入，显示和导航。特点是方便，易于实现。缺点是如果遇到IE7.0以上不兼容的网页，会造成显示不正常的问题；解决的方法是修改注册表中IE的Render mode ，使之兼容IE8，详见
第二种方法：使用其他第三方可以集成浏览器到WPF Application 的ActiveX组件，失败原因：一共找到两个组件。
一个是Mozilla的Firefox的组件（http://www.iol.ie/~locka/mozilla/mozilla.htm），该组件针对的Firefox版本太低，现在的网友没有实际的意义；
一个是Google Chrome Activex的组件（http://social.msdn.microsoft.com/Forums/en/wpf/thread/207139d2-ecd1-4b54-a94b-4eb340f95a19），在论坛上看到的，有人找到了，可是我没有找到。据称，该组件没有托管的。
第三种方法：基本思路是使用Process.Start("iexplore.exe", " www.msn.com.cn")打开一个IE的窗口，然后再使用SetParent将该新窗口并入WPF的主窗口中。代码如下（其他函数声明见附录）：
代码 var process = Process.Start("iexplore.exe", " www.msn.com.cn");
process.WaitForInputIdle();
//让IE准备好
Thread.Sleep(3000);
var ieHandle = FindWindow("ieframe", null);
SetParent(ieHandle, this.Handle);
int style = GetWindowLong(ieHandle, GWL_STYLE);
SetWindowLong(ieHandle, GWL_STYLE, (style & ~WS_CAPTION));
具体的思路是：
Create a WindowsFormsHost and add it to a panel in your UI
Start the process (such as Notepad) using Process.Start

Call process.WaitForInputIdle
Use process.MainWindowHandle to get the window handle
Call SetWindowPos to set the process's window to the coordinates and Z Order of the HwndHost window
Hook both the HwndHost and the process.MainWindowHandle to detect size changes and repeat step 5.
第四种方法：基本思路是使用反射获得IE对象（InternetExplorer Object，
http://msdn.microsoft.com/en-us/library/aa752084%28v=vs.85%29.aspx），然后设置相应的属性，最后将打开的新IE窗体，并入WPF程序中。
代码 System.Type oType =System.Type.GetTypeFromProgID("InternetExplorer.Application");
object o = System.Activator.CreateInstance(oType);
o.GetType().GetMembers();
o.GetType().InvokeMember("menubar",
System.Reflection.BindingFlags.SetProperty, null, o, new object[] { 0 });
o.GetType().InvokeMember("toolbar",
System.Reflection.BindingFlags.SetProperty, null, o, new object[] { 0 });
o.GetType().InvokeMember("statusBar",
System.Reflection.BindingFlags.SetProperty, null, o, new object[] { 0 });
o.GetType().InvokeMember("addressbar",
System.Reflection.BindingFlags.SetProperty, null, o, new object[] { 0 });
o.GetType().InvokeMember("Visible",
System.Reflection.BindingFlags.SetProperty, null, o, new object[] { true });
o.GetType().InvokeMember("Navigate",
System.Reflection.BindingFlags.InvokeMethod, null, o, new object[] { 你的URL });
var ieHandle = FindWindow("ieframe", null);
SetParent(ieHandle, this.Handle);
int style = GetWindowLong(ieHandle, GWL_STYLE);
SetWindowLong(ieHandle, GWL_STYLE, (style & ~WS_CAPTION));

备注：
1) 在一定的情况下，可以使用IE的K模式满足用户的要求，不必一定要嵌入自己的程序中。详见http://support.microsoft.com/kb/154780；
2) 在寻找的过程中，找了一下开源的项目，看有没有现成的wpf浏览器，结果没有找到。涉及的项目有Chromium WebBrowser WPF，WebBrowserEx，webbrowserc++，adhoc；
3) 在寻找的过程中，看到有人用WebApp.hta来实现网页的解析和载入，不过还是存在不兼容IE8.0的问题；
如果是直接调用默认浏览器打开网页建议使用进程直接打开，在这里可能会出现两种情况，如果这个链接是经过编码的打开网页后可能会出现乱码，在这里分享一下代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace SoftRGB.Controls
{
public static class AppServices
{
/// <summary>
/// 直接打开Uri类型的链接（经过转码后的string再经过tostring()会出现乱码，用另一个方法）
/// </summary>
/// <param name="uri"></param>
public static void OpenUri(Uri uri)
{
if (uri != null)
{
try
{
System.Diagnostics.Process.Start(uri.ToString());
}
catch
{
RGBMessageBox.Show("网址是：" + uri.ToString(), "网络浏览器调用失败，请确定你的电脑中安装了网络浏览器！", RGBMesType.Warn);
}
}
}
/// <summary>
/// 直接打开string类型的链接（可以是经过转码后的链接）
/// </summary>
/// <param name="uri"></param>
public static void OpenUri(string uri)
{
if (!string.IsNullOrEmpty(uri))
{
try
{
System.Diagnostics.Process.Start(uri);
}
catch
{
RGBMessageBox.Show("网址是：" + uri.ToString(), "网络浏览器调用失败，请确定你的电脑中安装了网络浏览器！", RGBMesType.Warn);
}
}
}
}
