        <fieldset>
            <legend>Registration Form</legend>
            <ol>
                <li class="lifile">
                    @Html.TextBoxFor(m => m.myFile, new { type = "file" })
                    @Html.ValidationMessageFor(m => m.myFile)

                </li>
            </ol>
            <input type="submit" id="btnSubmit" value="Upload" />
        </fieldset>
    }

For file uploading, you can use this code.

In controller:

[HttpPost]
public ActionResult Create(EventModel eventmodel, HttpPostedFileBase file)
{ 
   if (ModelState.IsValid)
   {

      //you can validate file here. if okay continue...

      var filename = Path.GetFileName(file.FileName);
      var path = Path.Combine(Server.MapPath("~/Uploads/Photo/"), filename);
      file.SaveAs(path);
      eventmodel.Url = filename;

      _db.EventModels.AddObject(eventmodel);
      _db.SaveChanges();
      return RedirectToAction("Index");
   }
   return View(eventmodel);
}

And View:

<div>
   Image
   <input type="file" name="file" id="file" />
   @Html.HiddenFor( model => model.ImageUrl)
   @Html.ValidationMessageFor( model => model.Url )
</div>
