我的代码是。为什么在实体框架5中成功修改了分离的实体?
class Program
{
static NorthwindEntities context = new NorthwindEntities();
static void Main(string[] args)
{
Order updateorder = new Order() { OrderID = 10256, ShipCountry = "444", ShipCity = "tehran" };
update(updateorder);
}
static public void update(Order updateorder)
{
context.Entry<Order>(updateorder).State = EntityState.Modified;
context.SaveChanges();
}
}
请帮帮我,我感到困惑,为什么脱离实体在数据库
