实现实体的部分更新
假设实体InfoHotel如下：
public class InfoHotel
{
public int Id{get;set;}
public string Name{get;set;}
public string Address{get;set;
public string Other1{get;set};
public string Other1{get;set};
public string Other2{get;set};
public string Other3{get;set};
}
有个网页仅仅修改Name和Address，保存的Action如下
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit([Bind(Include = "Id,Name,Address")] InfoHotel item)
{
if (ModelState.IsValid)
{
var oldItem = db.InfoHotels.Find(this.KeyCorp);
oldItem.Name = item.Name;
oldItem.Address = item.KeyCardRW;
oldItem.KeyPms = item.KeyPms;
db.SaveChanges();
return RedirectToAction("Index");
}
return View(item);
}
比较麻烦，可以改成
public ActionResult Edit([Bind(Include = "Id,Name,Address")] InfoHotel item)
{
if (ModelState.IsValid)
{
var oldItem = db.InfoHotels.Find(this.KeyCorp)
db.Entry(oldItem).CurrentValues.SetValues(item);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(item);
}
