HTML pages often use the META tag to embed arbitrary information about the document. The following HTML code example retrieves all of the META tags within an HTML document, finds the META tag with the name Description, and displays it to the user. The code example requires that your application has a WebBrowser control named WebBrowser1.

private void DisplayMetaDescription()
{
    if (webBrowser1.Document != null)
    {
        HtmlElementCollection elems = webBrowser1.Document.GetElementsByTagName("META");
        foreach (HtmlElement elem in elems)
        {
            String nameStr = elem.GetAttribute("name");
            if (nameStr != null && nameStr.Length != 0)
            {
                String contentStr = elem.GetAttribute("content");
                MessageBox.Show("Document: " + webBrowser1.Url.ToString() + "\nDescription: " + contentStr);
            }
        }
    }
}
