c# - 将属性从模型复制回对象——显式复制还是遍历属性集合？

Question

我正在获取一个对象并将其属性写入模型，然后在我的 View 中显示该模型以进行编辑。之后，用户点击提交，模型被发送回我的 Controller 。我现在想获取模型的属性并将它们写回对象。

我正在考虑使用反射来这样做，但我有点谨慎。我想我会检查是否有更明显的答案。

代码:

//OrderDetailsModel
public OrderDetailsModel(Order order)
{
    CompletionDateTime = order.CompletionDateTime;
    CreateDateTime = order.CreateDateTime;
    UpdateDateTime = order.UpdateDateTime;
    BusinessArea = order.BusinessArea;
    Comment = order.Comment;
    CostCenter = order.CostCenter;
    CreateUsername = order.CreateUsername;
    Customer = order.Customer;
    IncidentNumber = order.IncidentNumber;
    OrderID = order.ID;
    OrderStatus = order.OrderStatus;
    ProjectName = order.ProjectName;
    ProjectNumber = order.ProjectNumber;
    ProjectSubcode = order.ProjectSubcode;
    UpdateUsername = order.UpdateUsername;
    Description = order.Description;
}

//OrdersController
public ActionResult SaveOrderDetails(OrderDetailsModel orderDetailsModel)
{
    Order order = WorkflowManager.GetOrderByID(orderDetailsModel.OrderID);

    foreach(PropertyInfo propertyInfo in orderDetailsModel.GetType().GetProperties)
    {
         //Write properties back.
    }

    return null;
}

关于如何做到这一点的想法？

看看AutoMapper .它简化了左手<->右手编码的工作。

这是一个例子:

Mapper.CreateMap<Order, OrderDetailsModel>();
OrderDetailsModel dto = Mapper.Map<Order, OrderDetailsModel >(order);
