Unable to Call a method if i mentioned its attribute as HttpPost - asp.net-mvc

Question

I have a signin page which users can use to signin,i defined its method in controller as HttpPost,when i try to access it from browser,it shows no file found,if i remove the HttpPost attribute it hits the controller and return the view.Eventhough it pass the values in the form to controller if i didnt mentioned its type as HttpPost .Here my code of Login/SignIn.cshtml:
#model BOL.Player_Access
#using (Html.BeginForm("SignIn","Login",FormMethod.Post)){
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>Sign In</h4>
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.PlayerEmail, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.PlayerEmail, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.PlayerEmail, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.Password, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Password, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Password, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="SignIn" class="btn btn-default" />
</div>
</div>
</div>
And my LoginController Code is here
[AllowAnonymous] //This filter removes authorize filter for this controller alone and allow anonyomous request
public class LoginController : Controller
{
// GET: Login
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult SignIn(Player_Access plyr_obj)
{
return View();
}
}

Answer 1

You need code for both GET and POST.
You need a GET action to show the form that will be POST'ed
public ActionResult SignIn()
{
return View();
}
This will show the SignIn view.
Then you need a POST action to take the values from the form and send them to the controller.
[HttpPost]
public ActionResult SignIn(Player_Access plyr_obj)
{
//do some work to authenticate the user
return View();
}
