另外,请让我知道有没有更好的方法做同样的事情。
谢谢试试这个:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit(Person person)
{
if (ModelState.IsValid)
{
db.Entry(person).State = EntityState.Modified;
foreach (var phoneNumber in person.PersonPhoneNumbers)
db.Entry(phoneNumber).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
return View(person);
}
<div>
@Html.HiddenFor(model => model.PersonPhoneNumberId)
@Html.HiddenFor(model => model.PersonId)
</div>
<div class="form-group">
@Html.LabelFor(model => model.PhoneNumber, new { @class = "control-label col-md-2" })
