How do I get web browser element's css style?

Question

I have a page like the below in my web browser that I want to get the style atributte value. I tried:

 HtmlElement ele = webBrowser1.Document.GetElementById("foo");
            MessageBox.Show(ele.GetAttribute("style"));

but it output:

System.__ComObject

Why does it output a System.__ComObject type and how do I handle it?

HTML page:

<div id="foo" style="display:block;">
a
</div>

Answer 1

ele.Style

Will help.

ele.GetAttribute("Style")

won't work because returns string, so it can't say more than that is an object, while ele.Style returns CssStyleCollection.

Answer 2

var e = document.getElementById('foo');
var css = window.getComputedStyle(e,null).getPropertyValue("display");
alert(css);
