If you know what type of tag contains the inner HTML you want to get at, you could do something like this (this example loops through the div tags, but you could do p, or table cells, or whatever):

HtmlElementCollection collection = browser.Document.GetElementsByTagName("div");

foreach (HtmlElement element in collection) {
    string html = element.InnerHtml;
    string text = element.InnerText;
    // do something with the HTML or text here...
}

Or if you know the specific ID of the element you want to get, use:

HtmlElement element = browser.Document.GetElementById("someId123");
if(null != element) // do something with it...

You could give HtmlAgilityPack a try and follow this answer.

HtmlWeb webGet = new HtmlWeb();
HtmlAgilityPack.HtmlDocument doc = webGet.Load(url);
