Automapper to map Container to Containee-CodePudding

I'm kinda new to Automapper so I might try to use it for something it shouldn't be used for, but here it goes. I have two classes :

  public class Container
    {

        public int Id { get; set; }
        public string Code { get; set; }
        public string StrVal { get; set; }
        public DateTime Date { get; set; }
        public Containee Containee { get; set; }
    }  

  public class Containee
    {
        public int Id { get; set; }
        public decimal Value { get; set; }
        public string DifferentStr { get; set; }
        public DateTime birthday { get; set; }
    }

And I have a DTO that looks like this :

  public class ContaineeDTO
    {
        public int Id { get; set; }
        public decimal Value { get; set; }
        public string DifferentStr { get; set; }
        public DateTime birthday { get; set; }
        public string Code { get; set; }
    }

What I am trying to do is to use Automapper to map my Container to my ContaineeDTO. I feel like this should use a resolver, especially for passing Code from the Container to the Containee DTO, but I'm unsure about how to proceed, any help would be appreciated.

CodePudding user response：

You can place this configuration in Startup.cs:

var config = new MapperConfiguration(
    cfg => cfg.CreateMap<Container, ContaineeDTO>()
   .ForMember(containeeDto => containeeDto.Value, opt => 
       opt.MapFrom(container => container.Containee.Value))
   .ForMember(containeeDto => containeeDto.DifferentStr, opt => 
       opt.MapFrom(container => container.Containee.DifferentStr))
   .ForMember(containeeDto => containeeDto.birthday, opt => 
       opt.MapFrom(container => container.Containee.birthday));

Important note: you named properties same in two classes, so there is no necessity to provide their names in mapping definition (as you see, I didn't do it)
