Вот такой вид :

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

    @Html.AntiForgeryToken()

И это метод :

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit([Bind(Include = "Id,Content,Ctl,PublishDate,ExpiryDate,Exclude,Title1,Title2,Title3,Title4,Title5,ShortDescription1,ShortDescription2,ShortDescription3,ShortDescription4,ShortDescription5,LongDescription1,LongDescription2,LongDescription3,LongDescription4,LongDescription5,InsertDate,InsertBy,OrderBy")] ContentHtml contentHtml, HttpPostedFileBase file)
{
    return CreateEdit(file, contentHtml, false);
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "Id,Content,Ctl,PublishDate,ExpiryDate,Exclude,Title1,Title2,Title3,Title4,Title5,ShortDescription1,ShortDescription2,ShortDescription3,ShortDescription4,ShortDescription5,LongDescription1,LongDescription2,LongDescription3,LongDescription4,LongDescription5,InsertDate,InsertBy,OrderBy")] ContentHtml contentHtml, HttpPostedFileBase file)
{
    return CreateEdit(file, contentHtml, true);
}

private ActionResult CreateEdit(HttpPostedFileBase file, ContentHtml contentHtml, bool isCreate)
{
    if (ModelState.IsValid)
    {
        if (file != null)
        {
            file.SaveAs(HttpContext.Server.MapPath("/Content/Images/") + file.FileName);
            contentHtml.Ctl = ("/Content/Images/") + file.FileName;
        }

        if (isCreate)
        {


            db.ContentHtmls.Add(contentHtml);
            db.SaveChanges();

        }
        else
        {
            db.Entry(contentHtml).State = EntityState.Modified;
            db.SaveChanges();
        }
        return RedirectToAction("Index");
    }



    return View(contentHtml);
}

Когда я редактирую какую-либо запись , например поле TITLE1 , она обновляется , но изображение (поле Ctl)в ней удаляется . Я не знаю, почему это происходит здесь.У меня есть отладка кода, причем здесь

HttpPostedFileBase file

в методе редактирования файл имеет значение null.

Что я уже пробовал:

я просто объяснил проблему выше и свою попытку.
