HtmlMeta Class

HtmlMeta Class

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

Allows programmatic access to the HTML <meta> tag on the server.

Namespace: System.Web.UI.HtmlControls
Assembly: System.Web (in system.web.dll)

public class HtmlMeta : HtmlControl
public class HtmlMeta extends HtmlControl
public class HtmlMeta extends HtmlControl

The HtmlMeta control provides programmatic access to the HTML <meta> element on the server. The HTML <meta> element is a container for data about the rendered page, but not page content itself. The <meta> tag is placed between the opening and closing HTML <head> elements. Each <meta> element describes a metadata property name and its associated value.

Use the HtmlMeta control's Name property to specify the metadata property name, and the Content property to specify the metadata property value. Use the Scheme property to specify additional information to user agents on how to interpret the metadata property. Use the HttpEquiv property in place of the Name property when the resulting metadata property will be retrieved using HTTP.

You can get a reference to the page <head> element using the Header property of the Page object.

The following code example demonstrates how to use the HtmlMeta control to define HTML <meta> elements for a Web page. Two <meta> elements are defined, one listing keywords describing the page and one listing the date the page was created.

<%@ Page Language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">

<script runat="server">

  protected void Page_Load(object sender, EventArgs e)
    // Create two instances of an HtmlMeta control.
    HtmlMeta hm1 = new HtmlMeta();
    HtmlMeta hm2 = new HtmlMeta();    

    // Get a reference to the page header element.
    HtmlHead head = (HtmlHead)Page.Header;
    // Define an HTML <meta> element that is useful for search engines.
    hm1.Name = "keywords";
    hm1.Content = "words that describe your web page";
    // Define an HTML <meta> element with a Scheme attribute.
    hm2.Name = "date";
    hm2.Content = DateTime.Now.ToString("yyyy-MM-dd");
    hm2.Scheme = "YYYY-MM-DD";

<html xmlns="" >
<head runat="server">
    <title>HtmlMeta Example</title>
    <form runat="server">
    View the HTML source code of the page to see the two HTML meta elements added.
