推荐答案

请查看以下使用的Controller Action方法示例示例使用Entity Framework批量更新数据： -

Please have a look into the below sample example of a Controller Action method which is used to bulk update data using Entity Framework:-

[HttpPost]
public ActionResult Index(List<Contact> contactList)
{
	using (ContactEntities contactEntities = new ContactEntities())
        {
              foreach (var contact in contactList)
              {
                 var cnct = contactEntities.Contacts.Where(c => c.ContactID.Equals(contact.ContactID)).FirstOrDefault();
                 if (cnct != null)
                 {
                     cnct.ContactPerson = contact.ContactPerson;
                     cnct.Contactno = contact.Contactno;
                     cnct.EmailID = contact.EmailID;
                 }
              }
                 contactEntities.SaveChanges();
         }
              ViewBag.Message = "Successfully Updated.";
              return View(contactList);
}
