Whats the best way to programatically add a .swf to an asp.net page?

<object type="application/x-shockwave-flash" data="yourflash.swf" width="" height="">
<param name="movie" value="yourflash.swf">
</object>

namespace MyNamespace
{
 using System.Web.UI;

 public class FlashObject : Control
 { public int Width  {get;set}
   public int Height {get;set}
   [UrlProperty] pubic string SourceUrl {get;set;}

   protected override Render(HtmlWriter writer)
    { writer.WriteLine( "<object type='application/x-shockwave-flash' "
                       +" data='{0}' width='{1}' height='{2}'>rn"
                       +"    <param name='movie' value='{0}'>rn</object>"
                       ,ResolveUrl(SourceUrl)
                       ,Width
                       ,Height);
    }
 }
}

<system.web>
     <controls>
       <add tagPrefix="my" namespace="MyNamespace" assembly="MyAssembly" />
     </controls>
  </system.web>

<my:FlashObject SourceUrl='~/yourflash.swf' runat='server' />
