how to add mata keyword & meta description in ASP.NET?

There is no easy way to add but I have a simple method to introduce


pageEx.cs

using System;
using System.Data;
using System.Configuration;
using
System.Web;
using System.Web.Security;
using System.Web.UI;
using
System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public class PageEx : System.Web.UI.Page
{

private HtmlMeta
metaDescription = new HtmlMeta();
private HtmlMeta metaKeywords = new
HtmlMeta();

public string Description
{
get { return
metaDescription.Content; }
set { metaDescription.Content = value; }
}


public string[] Keywords
{
get
{
if
(metaKeywords.Content == null)
{
return new string[] { "" };
}
else
{
return metaKeywords.Content.Split(new char[] { ',' });
}
}

set
{
if (value != null)
{
metaKeywords.Content =
string.Join(",", value);
}
}
}


public PageEx()
{
Init += new EventHandler(PageEx_Init);
}

void PageEx_Init(object
sender, EventArgs e)
{
//Add the description Meta control
metaDescription.Name = "description";
Page.Header.Controls.Add(metaDescription);
//Add the keywords Meta
control
metaKeywords.Name = "keywords";
Page.Header.Controls.Add(metaKeywords);
}


}

someasp.aspx

protected void Page_Load(object sender, EventArgs e)
{

this.Description = "the power 123";
this.Keywords = new string[] {
"Enquiries", "enquiry", "contact", "contacts", "email", "tel" };

}

Hope this helps :)
