如何使用Automapper从一个简单的对象和方法调用创建复杂的视图模型对象 [英] How to use Automapper to create complex viewmodel objects from a simple object and a method call

问题描述

我的应用程序需要显示客户资料，包括有关客户和有关他最近从指定仓库订单数据表。客户域对象包含GetLatestOrder（warehouseId）方法。

My application needs to display a table of customer data, including data about the customer and about his most recent order from a given warehouse. The customer domain object contains a GetLatestOrder(warehouseId) method.

我有一个CustomerView视图模型，并希望能够从客户对象的某些字段，并从最新的订单对象几个字段来填充它。我能做到这一点使用Automapper？

I have a CustomerView viewmodel and want to be able to populate it with some fields from the customer object, and a few fields from the latest order object. Can I do this using Automapper?

推荐答案

在最后，我带着简单的方法，无法找到另一种方式：

In the end, I took the easy approach, couldn't find another way:

在的Application_Start：

In Application_start:

    Mapper.CreateMap<Customer, CustomerView>();
    Mapper.CreateMap<Order, CustomerView>();

在控制器的方法：

    IEnumerable<Customer> customers = GetCustomers(false)
                                               .OrderBy(c => c.Name);
    IEnumerable<CustomerView> viewData = Mapper.Map<IEnumerable<Customer>, IEnumerable<CustomerView>>(customers);
    foreach (Customer customer in customers)
    {
        CustomerView view = viewData.Where(cv => cv.CustomerId == customer.CustomerId).First();
        Mapper.Map(customer.GetLatestOrder(WarehouseId), view);
    }
