关于WebBrowser编程

Question

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));

Answer 1

((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WebBrowser2、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

Answer 2

动态绑定事件
//项目中添加Micrsoft.mshtml引用
