Automapper: map properties manually

Question

I just started to use automapper to map DTOs<->Entities and it seems to be working great.

In some special cases I want to map only some properties and perform additio

Answer 1

If I read your question correctly, yes, as long as your destination (target) property matches your conversion.

So if I am going from a string to a bool for a Status of "A" or "I" (active/inactive), I can do something like:

.ForMember(dest => dest.Status, opt => opt.MapFrom(src => src.Status == "A"))

And then when going the other direction, convert it back:

.ForMember(dest => dest.Status, opt => opt.MapFrom(src => src.Status ? "A" : "I"))

A date example:

.ForMember(dest => dest.SomeDate, opt => opt.MapFrom(src => src.SomeDate.ToString("M/d/yyyy")));
