Question

以这两个类为例：

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;}
}

在双向投标时如何忽略ProductDTO.Category？

Answer 1

假设您的意思是双向的，即两个类都有一个您想忽略的Category成员，您可以使用.ReverseMap()。

<强>映射

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
    {

    }
