For IE in standards mode (with a doctype, as you say) scrollTop is a property of the <html> element, not the <body> : 对于标准模式下的IE（如你所说的，带有doctype）， scrollTop是<html>元素的属性，而不是<body> ：
HtmlDocument htmlDoc = this.webBrowser1.Document;
int scrollTop = htmlDoc.GetElementsByTagName("HTML")[0].ScrollTop;
(A nicer way to get to the <html> element would be good, if anyone knows of one.) （一个更好的方法来获取<html>元素会很好，如果有人知道的话。）

are you trying to target an HTML element to bring it into view? 您是否尝试将HTML元素作为目标进行查看？ If that is what you are after you can do this... 如果你能做到这一点就是这样......
htmlDoc.GetElementById("tag_id_string_goes_here").ScrollIntoView(true); htmlDoc.GetElementById（ “tag_id_string_goes_here”）ScrollIntoView（真）。
true aligns it with the top and false with the bottom of the element. true将其与top对齐，false与元素的底部对齐。 You can also use ScrollRectangle to get the dimensions of the scrollable region. 您还可以使用ScrollRectangle来获取可滚动区域的尺寸。
