自動映射器映射到嵌套類

Question

我有1個類，我需要映射到多個類，例如。

這是我從（視圖模型）映射來源：

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; } 
} 

這是目標類是如何（域模型）：

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; } 

} 

這是怎麼了我的automapper創建地圖目前的樣子：

Mapper.CreateMap<UserBM, User>(); 

Answer 1

定義兩個映射，從相同的源到不同的目的地都映射。在User映射，使用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));
