【Vegas原创】继承，重写~

例：继承Web Parts，重写webparts中Reder方法：

using System;
using System.Collections.Generic;
using System.Text;
using System.Web.UI.WebControls.WebParts;

namespace PlatForm.Common

{

    public class AjaxWebPart:WebPart

    {

        protected override void Render(System.Web.UI.HtmlTextWriter writer)

        {

            //base.Render(writer);
        }

    }

}
