1) Install the automapper to your project through NuGet package manager
2) Initialize the automapper in the Global.asax file
protected void Application_Start()
{
AutoMapper.Mapper.Initialize(cfg => cfg.AddProfile<AutoMapperProfile>());
}
3) My classes to be mapped are:
//DAO classes
public class Passenger
{
public int OrderNo { get; set; }
[Key]
public int TcNo { get; set; }
public string PsgrName { get; set; }
public string FlightId { get; set; }
public string CarrierCode { get; set; }
public string FlightNo { get; set; }
public string Origin { get; set; }
public string Destination { get; set; }
public string DepDateTime { get; set; }
public string ArrDateTime { get; set; }
public virtual ICollection<Device> Devices { get; set; }
}
public class Device
{
public string Language { get; set; }
[Key]
public string RegistrationId { get; set; }
public string DeviceType { get; set; }
public int TcNo { get; set; }
}
//DTO classes to be mapped
public class PassengerDTO
{
public int OrderNo { get; set; }
public int TcNo { get; set; }
public string PsgrName { get; set; }
public string FlightId { get; set; }
public string CarrierCode { get; set; }
public string FlightNo { get; set; }
public string Origin { get; set; }
public string Destination { get; set; }
public string DepDateTime { get; set; }
public string ArrDateTime { get; set; }
public virtual ICollection<DeviceDTO> Devices { get; set; }
}
public class DeviceDTO
{
public string Language { get; set; }
public string RegistrationId { get; set; }
public string DeviceType { get; set; }
}
4) Create a mapper profile to map between the DAO and DTO object
public class AutoMapperProfile : Profile
{
public AutoMapperProfile()
{
CreateMap<Passenger, PassengerDTO>();
CreateMap<Device, DeviceDTO>();
}
}
5) Do the actual mapping in the code
IList<PassengerDTO> data = db.Passengers.Where(p => p.FlightId == FlightId).ProjectTo<PassengerDTO>().ToList();
