HtmlWindow.Frames Property

Note: This property is new in the .NET Framework version 2.0.

Gets a reference to each of the FRAME elements defined within the Web page.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in

public HtmlWindowCollection Frames { get; }
/** @property */
public HtmlWindowCollection get_Frames ()

public function get Frames () : HtmlWindowCollection

Property Value

An HtmlWindowCollection of a document's FRAME and IFRAME objects.

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.

The following code example inspects each document within a page containing frames and creates a table of all of the outgoing hyperlinks from each page for future inspection.

private void GetLinksFromFrames()
    Hashtable linksTable = new Hashtable();
    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");
            Hashtable docLinksHash = new Hashtable();
            linksTable.Add(webBrowser1.Document.Url.ToString(), docLinksHash);

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