<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script type="text/javascript">
    $(document).ready(function () {
        $('#btnPrintToken').click(function () {
            $.ajax({
                url: 'Home/btnPrintToken',
                type: 'POST',
                dataType: 'json',
                success: function (N) {
                    $('#listTokens').empty();
                    var listTokens = $('#listTokens');
                    $(N).each(function (index, x) {
                        var option = $("<option />");
                        option.html(x);
                        option.val(x);
                        listTokens.append(option);
                    });
                }
            });
        });
    });
</script>
<select id="listTokens" style="width: 100px">
</select>
<input type="button" id="btnPrintToken" value="Print Token" />

Controller

public class HomeController : Controller
{
    // GET: /Home/
    public ActionResult Index()
    {
        return View();
    }

    public JsonResult btnPrintToken()
    {
        if (Session["Tokenqueu"] == null)
        {
            Queue<int> queueToken = new Queue<int>();
            Session["Tokenqueu"] = queueToken;
        }
        List<int> listnumbertoken = new List<int>();
        Queue<int> tokenQueue = (Queue<int>)Session["Tokenqueu"];
        //string mesg = "There are" + tokenQueue.Count.ToString() + "Customer in the queue before you";
        if (Session["Lastnumbertoken"] == null)
        {
            Session["Lastnumbertoken"] = 0;
        }
        int nextnumbertoken = (int)Session["Lastnumbertoken"] + 1;
        Session["Lastnumbertoken"] = nextnumbertoken;
        tokenQueue.Enqueue(nextnumbertoken);

        foreach (int token in tokenQueue)
        {
            listnumbertoken.Add(token);
        }

        return Json(listnumbertoken, JsonRequestBehavior.AllowGet);
    }
}
