检测WebBrowser控件上的滚动

我有以下代码，奇怪的是，它工作了几秒钟然后停止工作（我的事件处理程序方法停止被调用）：

public partial class Form1 : Form { private void Form1_Load(object sender, EventArgs e) { webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted); webBrowser1.Navigate("google.com"); } private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { if (!webBrowser1.IsBusy && webBrowser1.Url == e.Url && webBrowser1.ReadyState == WebBrowserReadyState.Complete) { HTMLWindowEvents_Event windowEvents = webBrowser1.Document.Window.DomWindow as HTMLWindowEvents_Event; windowEvents.onscroll += new HTMLWindowEvents_onscrollEventHandler(windowEvents_onscroll); } } private void windowEvents_onscroll() { HtmlDocument htmlDoc = webBrowser1.Document; int scrollTop = htmlDoc.GetElementsByTagName("HTML")[0].ScrollTop; string text = scrollTop.ToString(); } }

确定找到解决方案：

  protected override void OnDocumentCompleted(WebBrowserDocumentCompletedEventArgs e) { Follow(); if (!IsBusy && Url == e.Url && ReadyState == WebBrowserReadyState.Complete) { Document.Window.AttachEventHandler("onscroll", DocScroll); } } 

如果以这种方式连接它可以正常工作（到目前为止……）。 甚至不需要使用mshtml。
