ASP.NET MVC：自动映射器合并类

发布于 2024-12-05 00:54:33 字数 726 浏览 0 评论 0 原文

我有这个代码：

public class OrderModel
{
    public List<Order> Orders { get; set; }
}

public class Order
{
    public string Code { get; set; }
    public DateTime CreationDate { get; set; }
    public Customer Customer { get; set; }
}

public class Customer
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

我想要一个 List MyClass 看起来像：

public class MyClass
{
    public string OrderCode { get; set; }
    public string OrderCreationDate { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Automapper 可以帮助我吗？如果没有其他解决方案来避免循环？

谢谢，

I have this code :

public class OrderModel

    public List<Order> Orders { get; set; }
}

public class Order
{
    public string Code { get; set; }
    public DateTime CreationDate { get; set; }
    public Customer Customer { get; set; }
}

public class Customer
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

I'd like get a List<MyClass> MyClass look like :

public class MyClass
{
    public string OrderCode { get; set; }
    public string OrderCreationDate { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Automapper can help me for this ? if no other solution to avoid loop ?

Thanks,

要使用 automapper 进行 DTO 展平，请参阅这个。他们应该回答你的问题。

如果您不想使用 automapper，我会使用简单的 Linq。像这样的东西

 var myClassList = (from p in OrderModel.Orders select new MyClass()
          {
            OrderCode = p.Code,
            OrderCreationDate = p.CreationDate,
            FirstName = p.Customer.FirstName,
            LastName = p.Customer.LastName
          }).ToList();

To do DTO flattening with automapper looks at this post and also this. They should answer your question.

If you don't want to use automapper I would use a simple Linq. Something like this

 var myClassList = (from p in OrderModel.Orders select new MyClass()
          {
            OrderCode = p.Code,
            OrderCreationDate = p.CreationDate,
            FirstName = p.Customer.FirstName,
            LastName = p.Customer.LastName
          }).ToList();
