Automapper with base class and different configuration options for implementations

Question

I have two classes (MVC view model) which inherits from one abstract base class.

abstract class BaseModel { }  class Car : BaseModel  {     public string Speed { get; set; } }  class Camper : BaseModel {     public int Beds { get; set; }  } 

and want to configure AutoMapper with base class, something like:

Mapper.CreateMap<BaseModel, DataDestination>();  var someObj = new DataDastination(); Mapper.Map(instanceOfBaseModel, someObj); 

Here I get error, because Automapper doesn't have configuration of Car or Camper. Tried configuring Automapper with something like this:

Mapper.CreateMap<BaseModel, DataDestination>()     .ForMember(dest => dest.SomeProp, mapper => mapper.MapFrom( .... )); 

In MapFrom, I only see properties from base class! How to configure Automapper to use BaseClass, and specific ForMember expression for Car and Camper? For example, if it's a Car, map this property from this, and if it's a Camper, map this property from somewhere else.

Here is the topic describing Mapping Inheritance.

The following should work for you:

Mapper.CreateMap<BaseModel, DataDastination>()     .Include<Car, DataDastination>()     .Include<Camper, DataDastination>();//.ForMember(general mapping) Mapper.CreateMap<Car, DataDastination>();//.ForMember(some specific mapping) Mapper.CreateMap<Camper, DataDastination>();//.ForMember(some specific mapping)
