Greetings, I have a pdf Dnn On my website, and I deplegar the window to open or save this Customer Pdf. I tried with this code but not deployed. What would be the way to do it .. With attention. This the code which throws no ..:

String filePath = Server.MapPath("~/DesktopModules/Ciber.Trs/pdf/Extracto.pdf");
 FileInfo targetFile = new FileInfo(filePath);
            if(targetFile.Exists){

               

             //Lanzar el Pdf al Cliente

                Response.Clear();
                Response.ClearContent();
                Response.ClearHeaders();
                Response.AddHeader("Content-Disposition", "attachment; filename=" + targetFile.Name);
                Response.ContentType = "application/pdf";
                Response.TransmitFile(Server.MapPath("~/DesktopModules/Ciber.Trs/pdf/Extracto.pdf"));
                Response.Flush();
                Response.End();

              }
