.net - ASP.NET MVC3 RAZOR: File Upload gives zero as file count

I need to upload multiple files into web server using MVC3 with RAZOR. I have the following code. In the controller, I am getting zero as the file count. How to correct it to get the actual number of files being uploaded and to get the content?

public class MyFileController : Controller
{

    public ActionResult MyFileProcessActionTest()
    {
        return View();
    }

    [HttpPost]
    public ActionResult MyFileProcessActionTest(IEnumerable<System.Web.HttpPostedFileBase> files)
    {

        int fileCount = files.Count<System.Web.HttpPostedFileBase>();
        return RedirectToAction("Index");
    }
}

VIEW

@{
ViewBag.Title = "MyFileProcessActionTest";
}

<h2>MyFileProcessActionTest</h2>

@using (Html.BeginForm())
{

<input type="file" name="files" id="file1" />
<input type="file" name="files" id="file2" />

<input type="submit"  />

}

You must include the enctype attribute in the form tag to indicate that the form should include files.

@using (Html.BeginForm("YourAction", "Controller", FormMethod.Post, new {enctype="multipart/form-data"))
{
}
