namespace  Ajax无刷新删除
{
     ///   <summary>
     ///  DeleteDataById 的摘要说明
     ///   </summary>
     public   class  DeleteDataById : IHttpHandler
    {

         public   void  ProcessRequest(HttpContext context)
        {
            context.Response.ContentType  =   " text/plain " ;
             int  id  =  Convert.ToInt32(context.Request[ " id " ]);
             new  T_CommentTableAdapter().DeleteDataById(id);
        }

         public   bool  IsReusable
        {
             get
            {
                 return   false ;
            }
