在构造函数中添加事件:

webBrowser.DocumentCompleted+=new WebBrowserDocumentCompletedEventHandler(webBrowser_DocumentCompleted);

void webBrowser_DocumentCompleted(object sender, System.Windows.Forms.WebBrowserDocumentCompletedEventArgs e)
{
       //滚动到制定位置
       webBrowser.Document.Window.ScrollTo(0, 1000);
}
