AutoMapper - Create mapping that combines Customer and Person into CustomerModel-CodePudding

Class Customer

public class Customer
{
    public int Id { get; set; }
    public int PersonId { get; set; }
    public int DiscountValue { get; set; }
    public Person Person { get; set; }
    public ICollection<Receipt> Receipts { get; set; }
}

Class Person

public class Person
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Surname { get; set; }
    public DateTime BirthDate { get; set; }
}

Class CustomerModel

public class CustomerModel
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Surname { get; set; }
    public DateTime BirthDate { get; set; }
    public int DiscountValue { get; set; }
    public ICollection<int> ReceiptsIds { get; set; }
}

I need to create mapping that combines Customer and Person into CustomerModel.

public class AutomapperProfile : Profile
{
    public AutomapperProfile()
    {
        CreateMap<(Customer, Person), CustomerModel>();
     }
}

How can I combine Customer and Person?

CodePudding user response：

You can just map from Customer to CustomerModel as:

Solution 1: Specify the property mapping from source to destination via .ForMember().

CreateMap<Customer, CustomerModel>()
    .ForMember(dest => dest.Name, opt => opt.MapFrom(src => src.Person.Name))
    .ForMember(dest => dest.Surname, opt => opt.MapFrom(src => src.Person.Surname))
    .ForMember(dest => dest.BirthDate, opt => opt.MapFrom(src => src.Person.BirthDate));

Solution 2: Flattening Person model via .IncludeMembers().

cfg.CreateMap<Customer, CustomerModel>()
    .IncludeMembers(src => src.Person);
            
cfg.CreateMap<Person, CustomerModel>();
