How can I get both a model and HttpPostedFileBase into a controller?

Question

I've looked quite a bit online, and every example I see explains how to get IEnumerable<HttpPostedFileBase> into a controller, OR how to get a model, but not both.

What I want is something like:

<form>
    <input type="text" name="Stored file name>
    <input type="file" multiple="multiple" name="files>
    <input type="submit">
</form>

with controller

[ActionName("Index"), HttpPost]
public ActionResult IndexPost(Models.MyModel mdl, IEnumerable<HttpPostedFileBase> files)
{
    // Do some something with the data in mdl and files here
    return RedirectToAction("Index");
}

But every way I try to implement this, it comes back 'no parameterless handler found'. It works fine if I don't include the model.

Am I missing something really obvious?

I guess you couldn't find Darin's this post. It's not exactly about passing model with HttpPostedFileBase but if you undrerstand the behavior the it's easy to do that.

See below example.

View

@model WebApplication2.Models.MyModel

@using (Html.BeginForm("Index", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    @Html.HiddenFor(m => m.Id)
    <input type="file" name="file" />
    <input type="submit" value="OK" />
}

Action Method

        [HttpPost]
        public ActionResult Index(MyModel model, HttpPostedFileBase file)
        {
            if (file != null)
            {
                //do your stuff here
            }
            return View();
        }
