insert many images which are in icollection in other model in asp mvc - asp.net-mvc

Question

My first model
public class article
{
public int id { set; get; }
public string title { set; get; }
public string bodyofarticle { set; get; }
public ICollection <image> images { set; get; }
}
The second model which I use to store the images URL in the database
public class image
{
public int id { set; get; }
public int articleid { set; get; }
public string url{ set; get; }
}
Form to enter the values its okay to enter the
article model but when I put any image it did not insert into the database
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>article</h4>
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.title, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.title, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.title, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.bodyofarticle, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.TextAreaFor(model => model.bodyofarticle, new { htmlAttributes = new { #class = "form-control" }, cols = 60, rows = 10 } )
#Html.ValidationMessageFor(model => model.bodyofarticle, "", new { #class = "text-danger" })
</div>
<input type="file" multiple id="file" name="file" />
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Create" class="btn btn-default" />
</div>
</div>
</div>
}
When I look at the break point I see that files are empty and I have tried many ways but it's still empty
public ActionResult Create([Bind(Include = "id,title,bodyofarticle")] article article , HttpPostedFileBase files)
{
if (ModelState.IsValid)
{
if (files != null && files.ContentLength >0 )
{
foreach (string file in Request.Files)
{
var v = Request.Files[file];
var fileName = Path.GetFileName(files.FileName);
var path = Path.Combine(Server.MapPath("~/images/"), fileName);
files.SaveAs(path);
image imag = new image();
imag.url = Url.Content("~/images/" + fileName);
article.images.Add(imag);
}
}
db.articles.Add(article);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(article);
}

Answer 1

Try this in the view. You will need to post the file from view.
#using (Html.BeginForm("Create", null, FormMethod.Post, new { enctype = "multipart/form-data" }))

Answer 2

Hope you used the command add-migrations before using the update-database command.

Answer 3

//it was at the view
#using (Html.BeginForm("Create", null, FormMethod.Post, new { enctype = "multipart/form-data" }))
