I want to pass all data to controller after clicking button.

 var data = new FormData();

Here is my javascript object

var info = {};
info.CorporateName = $("input[name*='CorporateName']").val();
info.CorporatePhone1 = $("input[name*='CorporatePhone1']").val();
info.CorporatePhone2 = $("input[name*='CorporatePhone2']").val();
info.CorporateEmail = $("input[name*='CorporateEmail']").val();

I can reach these datas from the controller with code below

$.each(info, function (key, input) {
            data.append(key, input);
        });

Here is my file list. I can reach these files from the controller with code below

var allfiles = $(".required-files");

for (var i = 0; i < allfiles.length; i++)
{
  var files = allfiles[i].files;
  data.append('files', files[0]);
}

Here is my packages cookie. I can't reach package list from the controller

var packageList = $.parseJSON($.cookie("packageList"));
 data.append('packageList',JSON.stringify(packageList));

I can post files, my info object but I can't post cookie list

Here is my controller

[HttpPost]
public async Task<IActionResult> create(IEnumerable<IFormFile> files, List<PostServiceDto> packageList, ModelDto Model)
        {
          // files = not null, Model not null, but packageList = null

            var model = Request.Form;

            return View();
        }

My package model

 public class PostServiceDto
    {
        public string Type { get; set; }
        public string Name { get; set; }
        public string Price { get; set; }
        public string Id { get; set; }
        public string Count { get; set; }
    }
