Just a possible useful extra where the submit button has not been given an Id - as is frequently the case.

    private HtmlElement GetInputElement(string name, HtmlDocument doc) {
            HtmlElementCollection elems = doc.GetElementsByTagName("input");

            foreach (HtmlElement elem in elems)
            {
                String nameStr = elem.GetAttribute("value");
                if (!String.IsNullOrEmpty (nameStr) && nameStr.Equals (name))
                {
                    return elem;
                }
            }
            return null;
    }

So you can call it like so:

 GetInputElement("Login", webBrowser1.Document).InvokeMember("Click");

It'll raise an exception if the submit input with the value 'Login', but you can break it up if you want to conditionally check before invoking the click.
