How to pass list of strings to view with action result method in ASP dotNet Core – Asp.net

I have an ActionResult Method which i wanted to return some values to the view for using in a form to submit afterwards.
How can I access these data from view for submition in a form?!

Here is my ActionResult method:

  

    [HttpPost]
    public virtual async Task<IActionResult> ImportPhonenumbersFromExcel(IFormFile importexcelfile, int currentFestivalId)
    {

        if (!await _permissionService.AuthorizeAsync(StandardPermissionProvider.ManageFestivals))
            return AccessDeniedView();

        try
        {
            if (importexcelfile != null && importexcelfile.Length > 0)
            {
                var result = await _importManager.ImportPhonenumbersFromXlsxAsync(importexcelfile.OpenReadStream());

            }
            else
            {
                _notificationService.ErrorNotification(await _localizationService.GetResourceAsync("Admin.Common.UploadFile"));
                return RedirectToAction("Edit", new { id = currentFestivalId });
            }
            _notificationService.SuccessNotification(await _localizationService.GetResourceAsync("Admin.Festival.Phonenumbers.Imported"));
            return RedirectToAction("Edit", new { id = currentFestivalId });

        }
        catch (Exception em)
        {
            await _notificationService.ErrorNotificationAsync(em);
            return RedirectToAction("Edit", new { id = currentFestivalId });
        }
    }

    You can create a view model that will contain the list and everything else you want to pass to the view.

    Then in the view you can access it by using @model.

    For strongly typed data a view model is the best option. It is a class with properties that can be used to store your specific values which you want to pass to the view. To use a viewmodel:

    • Create the viewmodel class and add the properties you need.

    • Instantiate a new viewmodel object in your controller. The example shown below is from the Microsoft documentation where the viewmodel class is named Address.

       public IActionResult Contact()
 {
     ViewData["Message"] = "Your contact page.";

     var viewModel = new Address()
     {
         Name = "Microsoft",
         Street = "One Microsoft Way",
         City = "Redmond",
         State = "WA",
         PostalCode = "98052-6399"
     };

     return View(viewModel);
 }

    • Once you have set the values of the properties of the viewmodel object in the controller you can then add the viewmodel to the view.

    • To send the viewmodel to the view, pass it as a parameter:

      return View(viewModel);

    • Finally, add to the top of your view file:

      @model yourViewModelsAddress

    To refer to the properties of your viewmodel in your view, follow this example:

    `@Model.Property`
