this is an extension method :

  public static List<System.Windows.Forms.HtmlElement> GetElementsByClassName(this System.Windows.Forms.WebBrowser browser, string TagName, string Classname)
    {
        var list = new List<System.Windows.Forms.HtmlElement>();
        var elements = browser.Document.GetElementsByTagName(TagName);
        foreach (System.Windows.Forms.HtmlElement link in elements)
            if (link.GetAttribute("className") == Classname)
                list.Add(link);

        return list;
    }

I found a working answer here: https://social.msdn.microsoft.com/Forums/vstudio/en-US/a22cafb7-f93c-4911-91ce-b305a54811fa/how-to-get-element-by-class-in-c

Get the "className" attribute.


static IEnumerable<HtmlElement> ElementsByClass(HtmlDocument doc, string className)
{
  foreach (HtmlElement e in doc.All)
    if (e.GetAttribute("className") == className)
      yield return e;
}
