Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Source:

HtmlWindow.cs

Gets the HTML document contained within the window.

C#

public System.Windows.Forms.HtmlDocument? Document { get; }

Property Value

HtmlDocument

A valid instance of HtmlDocument, if a document is loaded. If this window contains a FRAMESET, or no document is currently loaded, it will return null.

Examples

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.

C#

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");
                }
            }
        }
        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

Typically, you will access the Document through the Document property of the WebBrowser control. Use this property when you need to access a document within a FRAME using the Frames collection.
