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

You can make some projection using MapFrom method - http://automapper.readthedocs.io/en/latest/Projection.html

Mapper.Map(source, target)
   .ForMember(m => m.Property, opt => opt.MapFrom(src => src.ChangedProperty));

For example (reffering to AutoMapper documentation):

// Model
var calendarEvent = new CalendarEvent
    {
        Date = new DateTime(2008, 12, 15, 20, 30, 0),
        Title = "Company Holiday Party"
    };

// Configure AutoMapper
Mapper.CreateMap()
    .ForMember(dest => dest.EventDate, opt => opt.MapFrom(src => src.Date.Date))
    .ForMember(dest => dest.EventHour, opt => opt.MapFrom(src => src.Date.Hour))
    .ForMember(dest => dest.EventMinute, opt => opt.MapFrom(src => src.Date.Minute));
