Question

Let us say my domain object can contain a bunch of objects like this:

List<Thing> Things

where Thing is defined like this:

class Thing
(
    public int ThingId { get; set; }
    public string ThingName { get; set; }
)

My DTO contains

List<string> ThingIds;
List<string> ThingNames;

The question is how can I use automapper to map Things to the ‘relevant bits’ in the DTO?

Thanks.

Answer 1

By writing custom resolver, i guess.

That’s quite unusual requirement – to lose binding between id and name.

I think you are right. sorry I am still learning about the dto/viewmodel mapping. Do you think it is acceptable to put a domain object inside a DTO as there is not much point in creating a dto for Thing?

Do not mix domain model inside view model. You will regret that next week (i did for sure…).

class Thing {
    public int ThingId { get; set; }
    public string ThingName { get; set; }
    public string UnnecessaryProp {get;set;}
}

class ThingViewModel {
    public int ThingId { get; set; }
    public string ThingName { get; set; }
}

class MyView {
    public IEnumerable<ThingViewModel> Things {get;set;}
}
