Automapper将Viewmodel映射到具有相同名称的Model

Question

Viewmodel

public string Personal_Data_Surname { get; set; }
public string FamilyMember_SurName { get; set; }

Entity class Applicant

public string SurName { get; set; }

Entity class FamilyMember

public string SurName { get; set; }

Automapper Config

        Mapper.Configuration.RecognizePrefixes("Personal_Data_");
        Mapper.CreateMap<ApplicationViewModel, Applicant>();

        Mapper.Configuration.RecognizePrefixes("FamilyMember_");
        Mapper.CreateMap<ApplicationViewModel, FamilyMember>();

Controller code mapping entities

Applicant applicant = Mapper.Map<ApplicationViewModel, Applicant>(vaModel);
FamilyMember familyMember = Mapper.Map<ApplicationViewModel, FamilyMember>(vaModel);

The problem is that it maps Personal_Data_Surname from the viewmodel to the Surname in entity class Applicant and FamilyMember. Is it possible to specify a prefix for a specific type

Answer 1

You have to customize your mapping using ForMemeber method, with the MapFrom option method, for sample:

Mapper.CreateMap<ApplicationViewModel, Applicant>()
       .ForMember(viewModel => viewModel.Personal_Data_Surname, 
                  opt => opt.MapFrom(entity => entity.SurName));

Then, AutoMapper will map the Personal_Data_Surname viewModel's property to SurName entity's property. Do it to another entities.
