Question

The below code is sample I typed
After I submit passing null values to controller, In Controller I have used the Class name then value passing correctly but when i used the parameter it passing NULL values to the controller. Please give me a solution..

Controller:

[HttpGet]
        public ActionResult Index()
        {
            return View();
        }


        [HttpPost]
        public ActionResult Index(string firstname)
        {
            LogonViewModel lv = new LogonViewModel();
            var ob = s.Newcustomer(firstname)

            return View(ob );
        }

View:

@model IList<clientval.Models.LogonViewModel>

@{
    ViewBag.Title = "Index";
}

@using (Html.BeginForm())
{
    for (int i = 0; i < 1; i++)
    {  
    @Html.LabelFor(m => m[i].UserName)
    @Html.TextBoxFor(m => m[i].UserName)
     @Html.ValidationMessageFor(per => per[i].UserName)

    <input type="submit" value="submit" />

        [HttpPost]
        public ActionResult Index(IList<LogonViewModel> obj)
        {

            LogonViewModel lv = new LogonViewModel();
            var ob = lv.Newcustomer(obj[0].FirstName)

            return View(ob );
        }
