C# ASP.Net日期字段值在每次编辑时重置

C# ASP.Net日期字段值在每次编辑时重置,c#,asp.net,C#,Asp.net,在我的ASP.Net项目中,我的模型具有以下属性: [DataType(DataType.Date)] public Nullable<System.DateTime> dt_ent { get; set; } 控制器: public ActionResult Edit(int? id) { if (id == null) { return new HttpStatusC

在我的ASP.Net项目中,我的模型具有以下属性:

[DataType(DataType.Date)]
public Nullable<System.DateTime> dt_ent { get; set; }
控制器:

        public ActionResult Edit(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            Process process = db.Process.Find(id);
            if (process == null)
            {
                return HttpNotFound();
            }

            return View(process);
        }

    [HttpPost]
    [ValidateAntiForgeryToken]

    public ActionResult Edit([Bind(Include = "id,dt_ent")] Process process)
    {
            if (ModelState.IsValid)
            {

                db.Entry(process).State = EntityState.Modified;
                db.SaveChanges();
                return RedirectToAction("Index");

            }

    }

在此处编写html代码。视图是使用标准EF操作创建的。编辑日期字段后,在视图/控制器交互方面会发生什么?您可以发布处理此编辑的操作吗?已添加控制器。
        public ActionResult Edit(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            Process process = db.Process.Find(id);
            if (process == null)
            {
                return HttpNotFound();
            }

            return View(process);
        }

    [HttpPost]
    [ValidateAntiForgeryToken]

    public ActionResult Edit([Bind(Include = "id,dt_ent")] Process process)
    {
            if (ModelState.IsValid)
            {

                db.Entry(process).State = EntityState.Modified;
                db.SaveChanges();
                return RedirectToAction("Index");

            }

    }
