    string frameUrl;

    if (!(webBrowser1.Document == null))
    {
        HtmlWindow currentWindow = webBrowser1.Document.Window;
        if (currentWindow.Frames.Count > 0)
        {
            foreach (HtmlWindow frame in currentWindow.Frames)
            {
                frameUrl = frame.Url.ToString();
                Hashtable frameLinksHash = new Hashtable();

                linksTable.Add(frameUrl, frameLinksHash);
                foreach (HtmlElement hrefElement in frame.Document.Links)
                {
                    frameLinksHash.Add(hrefElement.GetAttribute("HREF"), "Url");
                }
            }
        }
        else
        {
            Hashtable docLinksHash = new Hashtable();
            linksTable.Add(webBrowser1.Document.Url.ToString(), docLinksHash);

            foreach (HtmlElement hrefElement in webBrowser1.Document.Links)
            {
                docLinksHash.Add(hrefElement.GetAttribute("HREF"), "Url");
            }
        }
    }
}

Remarks

A FRAME is a set of windows defined within a FRAMESET. FRAMEs enable hosting multiple documents within a single document. Each FRAME is defined as possessing a certain row and column width, and is position on the page in relation to the other FRAMEs defined within the FRAMESET; the position of a FRAME is fixed, although a user may sometimes use the mouse cursor to grow or shrink the FRAME. An IFRAME is similar to a frame, but it need not be anchored in a fixed position.

Frames will contain one instance of HtmlWindow for each FRAME or IFRAME defined within a Web page.
