Automapper地图为嵌套类 [英] Automapper map into nested class

问题描述

我有1类，我需要T映象成多个类别，例如为

I have 1 class that I need t map into multiple classes, for eg.

这是我从（视图模型）的映射源：

This is the source that I'm mapping from(view model):

public class UserBM
{
    public int UserId { get; set; }

    public string Address { get; set; }
    public string Address2 { get; set; }
    public string Address3 { get; set; }
    public string State { get; set; }

    public int CountryId { get; set; }
    public string Country { get; set; }
}

这是目标类是如何（域模型）：

This is how the destination class is(domain model):

public abstract class User
{
    public int UserId { get; set; }

    public virtual Location Location { get; set; }
    public virtual int? LocationId { get; set; }
}

public class Location
{
    public int LocationId { get; set; }

    public string Address { get; set; }
    public string Address2 { get; set; }
    public string Address3 { get; set; }
    public string State { get; set; }

    public virtual int CountryId { get; set; }
    public virtual Country Country { get; set; }

}

这是我的automapper如何创建地图目前的样子：

This is how my automapper create map currently looks:

Mapper.CreateMap<UserBM, User>();

推荐答案

定义两个映射，来自相同源到不同的目的地都映射。在用户映射，映射属性手动使用 Mapper.Map＆LT的位置; UserBM，地点＆gt （......）

Define two mappings, both mapping from the same source to different destinations. In the User mapping, map the Location property manually using Mapper.Map<UserBM, Location>(...)

Mapper.CreateMap<UserBM, Location>();
Mapper.CreateMap<UserBM, User>()
    .ForMember(dest => dest.Location, opt => 
         opt.MapFrom(src => Mapper.Map<UserBM, Location>(src));
