如何向下滚动页面加载时 - GeckoFx C＃

Question

我想向下滚动，而页面加载在geckofx 45. 我试图做下面的代码，但它似乎不工作。

wb.Navigate("javascript: var s = function() { window.scrollBy(550, 10000); }; s();"); 

这怎么可能？

int scrollTo = 30; 
    public void scrollDown() 
    { 
     this.wb.Focus(); 
     string result = string.Empty; 
     AutoJSContext context; 
     string jsScript = string.Empty; 
     try 
     { 
      if (scrollTo > 100) 
      { 
       scrollTo = 5; 
      } 

      context = new AutoJSContext(this.wb.Window); 
      jsScript = "var x = document.getElementsByClassName('ANY_ELEMENTS_CLASS_NAME'); x[" + (scrollTo * 2) + "].scrollIntoView(); ";// CHANGE ANY_ELEMENTS_CLASS_NAME 

      context.EvaluateScript(jsScript, (nsISupports)wb.Window.DomWindow, out result); 
      scrollTo += 5; 
     } 
     catch (Exception e) 
     { 
     } 
    }
