忽略导航属性时，映射Automapper

Question

有了这2类为例：

public class Product 
{ 
    public int Id {get; set;} 
    public int CategoryId {get; set;} 
} 

public class ProductDTO 
{ 
    public int Id {get; set;} 
    public int CategoryId {get; set;} 
    public Category Category {get; set;} 
} 

我怎能无视ProductDTO.Category bidrectionally映射时？

Answer 1

假设你的意思是双向的，即两个类都有一个你想忽略的Category成员，你可以使用.ReverseMap()。

映象

Mapper.CreateMap<Product, ProductDTO>()     
       .ForMember(dest => dest.Category, opt => opt.Ignore()).ReverseMap(); 

示例模型

public class Product 
    { 
     public int Id {get; set;} 
     public int CategoryId {get; set;} 
     public Category Category {get; set;} 
    } 

    public class ProductDTO 
    { 
     public int Id {get; set;} 
     public int CategoryId {get; set;} 
     public Category Category {get; set;} 
    } 

    public class Category 
    { 

    }
