HtmlWindow.Frames Property

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

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

public HtmlWindowCollection Frames { get; }

Property Value

Type: System.Windows.Forms.HtmlWindowCollection
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");
