show all selected options in Multiselect mvc c# after the submit

Hi,

How can I show all selected items after the submit?

Can someone help me and tell me what I'm doing wrong please?

Model :


        public IEnumerable<SelectListItem> VersionList { get; set; }

        public List<string> SelectedVersion { get; set; }


      public IEnumerable<SelectListItem> GetVersion()
        {
            var GetVersion = _unitOfWorkCABusinessRules.RuleDetailRepo.GetAll().GroupBy(x => x.Version).Select(y => y.First()).Distinct();

            return GetVersion
                 .Select(x => new SelectListItem
                 {
                     Text = x.Version,
                     Value = x.Version.ToString(),
                 })
                .Distinct()
                .OrderBy(x => x.Text);
        }

controller: 


 [HttpPost]
  public ActionResult SearchRules(CABRSearchRules model, string[] SelectedVersion)
        {

              model.VersionList = _careAdvanceBusinessRulessService.GetVersion();
            model.SelectedVersion = SelectedVersion.ToList();

      return View(model);
        }

        $('#SelectedVersion').multiselect({
            onInitialized: function (option, checked) {
                var values = [];
                var dropdown = $('#SelectedVersion').siblings('.multiselect-container');
                $('#SelectedVersion option').each(function () {
                    values.push($(this).text());
                });
            },
