关于WebBrowser编程

[chenyang80425]

WebBrowser webBrowser1;
this.webBrowser1.Navigate(this.url);
((WebBrowser)this.webBrowser1.ActiveXInstance).add_NavigateComplete2(new DWebBrowserEvents2_NavigateComplete2EventHandler(this.wb_NavigateComplete2));
this.htmlCatched += new HtmlCatched(this.Form2_htmlCatched);
this.timer.Tick += new EventHandler(this.timer_Tick);
this.timer.Start();


请问这段是什么意思了?((WebBrowser)this.webBrowser1.ActiveXInstance).add_NavigateComplete2(new DWebBrowserEvents2_NavigateComplete2EventHandler(this.wb_NavigateComplete2));

看起来像添加一个事件，但是写法又稍有不同。

[捷哥1999]

((WebBrowser)this.webBrowser1.ActiveXInstance).add_NavigateComplete2(new DWebBrowserEvents2_NavigateComplete2EventHandler(this.wb_NavigateComplete2));

1、((WebBrowser)this.webBrowser1.ActiveXInstance)
强制类型转换，得到WebBrowser

2、add_NavigateComplete2
调用add_NavigateComplete2方法，动态添加事件绑定

3、new DWebBrowserEvents2_NavigateComplete2EventHandler(this.wb_NavigateComplete2)
add_NavigateComplete2的参数为DWebBrowserEvents2_NavigateComplete2EventHandler委托实例
创建该委托对象时，传入this.wb_NavigateComplete2

这样当触发NavigateComplete2事件后，会执行this.wb_NavigateComplete2

请问要引用哪个类才编译得过了?我编译出错了.

动态绑定事件
