สอบถามเรื่องการ Download file โดยใช้ jquery เรียก Controller (C#)

[HttpPost]
        public ActionResult Download(WhtSubmit SubmitInfo)
        {
            string fileSavePath = System.Web.Hosting.HostingEnvironment.MapPath("~/documents/wht");
            DirectoryInfo dirInfo = new DirectoryInfo(fileSavePath);

            //return dirInfo.FullName + @"\PV001.pdf";

            using (var memoryStream = new MemoryStream())
            {
                using (var ziparchive = new ZipArchive(memoryStream, ZipArchiveMode.Create, true))
                {
                    foreach(var fileCol in SubmitInfo.AxVoucher)
                    {
                        ziparchive.CreateEntryFromFile(dirInfo.FullName+@"\"+ fileCol, fileCol);
                    }
                }

                return File(memoryStream.ToArray(), "application/zip", "Attachments.zip");
            }
        }

function Submit()
    {
        var array = [];

        $("#id:checked").each(function () {
            array.push($(this).val());
        });

        var WhtSubmit = {
            AxVoucher: array
        }

        $.ajax({
            method: "POST",
            url: "@Url.Action("Download", "Wht")",
            data: WhtSubmit,
            /*contentType: 'application/json; charset=utf-8',
            dataType: 'JSON',*/
            success: function (res) {
                window.open("data:application/zip;");
            }
        });
    }
