C#2.0，winform程序，怎么样实现点击webBrowser某个链接，显示某个form

<iframe marginwidth="0" marginheight="0" src="http://218.16.120.35:65001/PC/Global/images/b.html" frameborder="0" width="728" scrolling="no" height="90"></iframe>

//通过e.Url判断，用户打开的连接
//当然要排除第一次打开的网页

private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e)
{
if (e.Url.ToString().Equals("http://www.xxx.xxx/",
StringComparison.OrdinalIgnoreCase))
return;
e.Cancel = true;
Form2 form2 = new Form2();
form2.Text = e.Url.ToString();
form2.Show();
}
