I am using below code to generate pdf of booked ticket and a pdf is generated and displayed but I want that pdf will save in a folder so that I can send it to email address of user.

public ActionResult ReportSample(tbbooking tbbook)
        {
            var uemail = Convert.ToString(Session["uemail"]);
            var bookingid = tbbook.bookingid;
            var getticket = db.tbbookings.Where(a => a.bookingid == tbbook.bookingid).ToList();
            return new RazorPDF.PdfResult(getticket, "ReportSample");
            
        }
