How to use Automapper in ASP.NET Core to create mapping configuration for the following type of hierarchy - asp.net-core

Question

I would like to map the following hierarchy of entities to the TestViewModel class. I have TestViewModel class with the same member names and perhaps I will add more members to the view model. I am using AutoMapper.
public class TestProfile : Profile
{
public TestProfile ()
{
CreateMap ??????
}
}
public class Test
{
public List<Test1> Tests1 { get; set; }
public int TestId { get; set; }
}
public class Test1
{
public int Test1Id { get; set; }
public string Name { get; set; }
public List<Document> Documents { get; set; }
}
public class Document
{
public int DocumentId { get; set; }
public DateTimeOffset? ChangeDate { get; set; }
public List<Payload> Payloads { get; set; }
}
public class Payload
{
public string PayloadName { get; set; }
}

Answer 1

You didn't tell us what your TestViewModel class looks like, and whether you also have DocumentViewModel, PayloadViewModel, etc. Typically if you are mapping to a another set of classes that have the same naming and structure, like a set of ViewModels, you will want to have a configuration like this:
public class TestProfile : Profile
{
public TestProfile()
{
CreateMap<Test, TestViewModel>();
CreateMap<Test1, Test1ViewModel>();
CreateMap<Document, DocumentViewModel>();
CreateMap<Payload, PayloadViewModel>();
}
}
This will map all like-named properties between the two sets of classes. If your TestViewModel shares the same child entities, then you only need the first line.
