运行环境:win7 64位，Visual Studio 2010，IE9浏览器(Watin目前只支持IE 和 FireFox的部分版本)
控制台项目测试代码:
1 [STAThread]
2 static void Main(string[] args)
3 {
4 //IE ie = new IE("http://localhost:3040/Test2.htm");
5 IE ie1 = new IE("http://www.baidu.com");
6 }
2 static void Main(string[] args)
3 {
4 //IE ie = new IE("http://localhost:3040/Test2.htm");
5 IE ie1 = new IE("http://www.baidu.com");
6 }
行号4用IE打开一个本地Web项目的资源，行号5以百度的网址打开IE，打开百度的代码没有报错，但是打开本地Web项目的网址出现以下异常:
Unhandled Exception: System.Runtime.InteropServices.COMException: 接口未知。 (Ex

请按任意键继续. . .

下面再看下在Web项目中使用Watin遇到的问题:
测试代码:
1 public partial class _Default : System.Web.UI.Page
2 {
3 protected void Page_Load(object sender, EventArgs e)
4 {
5 IE ie = new IE("http://localhost:3040/About.aspx");
6
7 }
8 }
2 {
3 protected void Page_Load(object sender, EventArgs e)
4 {
5 IE ie = new IE("http://localhost:3040/About.aspx");
6
7 }
8 }
和控制台项目一样打开百度的链接没有问题，但是打开项目中的 About.aspx文件是报出以下错误信息:
Server Error in '/' Application.

上面的两个错误信息让我郁闷了很久，查阅资料后有两种解决办法:
1.以管理员身份的方式运行Visual Studio 2010
2.禁用IE浏览器的本地(Intranet)选项的 保护模式，打开 工具-> Internet 选项->安全->本地(Intranet) 然后取消安全模式的勾选 即可
目前只是解决问题，造成问题的具体原因，有待分析。
最新解决办法:
Interop.SHDocVw.dll 和.exe放在一个目录就行了
将引用“Interop.SHDocVw”的属性“嵌入互操作类型”由True改为False
