分别编辑后尝试保存在交付和订单的 POST 方法中时未处理 DbUpdateException
DbUpdateException unhandled when trying to save in POST method of Delivery and Order after editing respectively
在我编辑 Delivery 或 Order 后，我似乎在 db.SaveChanges() 上收到 DbUpdateException 错误。我不确定为什么，它适用于 Create 和 Delete。
我是不是漏了什么地方？ GET Edit 方法对两者都适用。
我得到这个 exception 错误：
System.Data.Entity.Infrastructure.DbUpdateException was unhandled by
user code HResult=-2146233087 Message=An error occurred while
updating the entries. See the inner exception for details.

请注意： 我没有将 ViewModels 用于 Edit Order，仅用于 Edit Delivery。
错误的重要部分是
Message=The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value`.
Delivery 和 Order 都有多个 DateTime 字段，并且至少有一个字段在您保存时未设置，因此它们的值为 01/01/0001（即 DateTime.MinValue)，但您的数据库 table 字段是 DATETIME，它的年份范围仅为 1753-9999。为防止错误，您可以将 sql 类型更改为与 c# DateTime 范围匹配的 DATETIME2。
但是，我怀疑真正的问题是您真的应该设置 DateTime 属性。您的 Edit() POST 方法有
Delivery delivery = new Delivery()
{
DriverID = model.DriverID,
};
db.Deliverys.Add(delivery);
然而 Edit() 方法建议您编辑现有对象，因此它应该是
// Get the data model based on the ID of the view model
Delivery delivery = db.Delivery.Find(model.ID);
// Map the view model properties to the data model
delivery.DriverID = model.DriverID;
// Mark as modified and save
db.Entry(order).State = EntityState.Modified;
db.SaveChanges();
在我编辑 Delivery 或 Order 后，我似乎在 db.SaveChanges() 上收到 DbUpdateException 错误。我不确定为什么，它适用于 Create 和 Delete。
