Automapper 8.1.1 how to configure

Jun 30, 2019 09:02 PM|cenk1536|LINK

Hi,

I would like to use automapper in order to transform dto to entities. I followed this article (https://www.infoworld.com/article/3192900/how-to-work-with-automapper-in-c.html) but couldn't figure it out where to put MapperConfiguration. Any help would be great.

Here is my Business Services:

public async Task<GameConfirmResponse> GamePurchase(RequestDto requestDto)
        {
            using (var scope = new TransactionScope())
            {
                //Unique reference ID
                var game = new GameRequest {referenceId = Guid.NewGuid().ToString()};
                //Transform DTO into GameRequest for calling Razer Initiate
                var gameRequest = Mapper.Map<RequestDto, GameRequest>(requestDto);
                gameRequest = Utilities.CreateSignature(gameRequest, RequestType.Initiate);
                //Insert request into database
                _unitOfWork.GameRepository.Insert(gameRequest);

                #region Call Razer initiate

                var response = await Utilities.CallRazer(gameRequest, "purchaseinitiation");
                //Read response
                var htmlResponse = await response.Content.ReadAsStringAsync();

                var gameResponse = JsonConvert.DeserializeObject<GameResponse>(htmlResponse);
                //Adding response into database
                _unitOfWork.GameResponseRepository.Insert(gameResponse);
                
                if (gameResponse.initiationResultCode == "00")
                {

                }
                #endregion
                await _unitOfWork.SaveAsync();
                
                var gameConfirmResponse = Mapper.Map<RequestDto, GameConfirmResponse>(requestDto);
                scope.Complete();
                
                return gameConfirmResponse;
            }
        }

As far as I know, if you want to use automapper instance API, you could create a class named AutoMapperConfig.cs.

Then you could add the Create the AutoMapper Configuration Class and add your mapping profile class here.

At last, you could directly call the AutoMapper Configuration's method to create the config and then using config.CreateMapper metho to create the mapper.

More details, you could refer to below codes:

AutoMapperConfig.cs

    using AutoMapper;
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
     using MVCNormallIssue.Models;

    namespace MVCNormallIssue.App_Start
    {
        public class AutoMapperConfig
        {
            //public static void config()
            //{
            //    Mapper.Initialize( cfg => cfg.CreateMap<Author,AuthorDTO>());
            //}

            public MapperConfiguration Configure()
            {
                var config = new MapperConfiguration(cfg =>
                {
                    //way one 
                    cfg.CreateMap<Author, AuthorDTO>();
                    //way two
                    cfg.AddProfile<AuthorMappingProfile>();
                }
               );

                return config;
            }
        }

        //way two 
        public class AuthorMappingProfile : Profile
        {
            public AuthorMappingProfile()
            {
                CreateMap<Author, AuthorDTO>().ReverseMap();
            }
        }
    }

Controller:

using AutoMapper;
using MVCNormallIssue.App_Start;
using MVCNormallIssue.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MVCNormallIssue.Controllers
{
    public class AutoMapperTestController : Controller
    {
        // GET: AutoMapperTest
        public ActionResult Index()
        {
            //Obsolete
            //Mapper.Initialize(x => x.CreateMap<Author, AuthorDTO>());

            //For member used to customsize the mapper
            // var config = new MapperConfiguration(cfg => { cfg.CreateMap<Author, AuthorDTO>().ForMember(destination => destination.NameAndAge, opts => opts.MapFrom(x => x.Name + "is" + x.Age)); });

            var config = new AutoMapperConfig().Configure();

            IMapper imapper = config.CreateMapper();

            var source = new Author() { Id=1, Age="20", Name="Test1" };
            //way one if the destination object not exists
            var re = imapper.Map<Author, AuthorDTO>(source);

            //way two if the destination object is existed

            var des = new AuthorDTO();

            imapper.Map(source, des);



            return View();
        }
    }
}

Hi Brando,

Can I add multiple maps inside this?

var config = new MapperConfiguration(cfg =>
                {
                     
                    cfg.CreateMap<Author, AuthorDTO>();
                   cfg.CreateMap<Game, GameDTO>();
                   cfg.CreateMap<Dog, DogDTO>();
                   
                }

I use mapping in business serive layer as follows. Should I create AutoMapperConfig class in this layer?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Threading.Tasks;
using System.Transactions;
using AutoMapper;
using BusinessEntities;
using BusinessService.Utility;
using DataModels;
using Newtonsoft.Json;

namespace BusinessService
{
    public class GameServices : IGameServices
    {
        private readonly UnitOfWork _unitOfWork;

        /// <summary>
        /// Public constructor.
        /// </summary>
        public GameServices(UnitOfWork unitOfWork)
        {
            _unitOfWork = unitOfWork;
        }


        /// <summary>
        /// Creates a game
        /// </summary>
        /// <param name="requestDto"></param>
        /// <returns></returns>
        public async Task<GameConfirmResponse> GamePurchase(RequestDto requestDto)
        {
            using (var scope = new TransactionScope())
            {

                //Transform DTO into GameRequest for calling Razer Initiate
                var config = new MapperConfiguration(cfg => {
                    cfg.CreateMap<RequestDto, GameRequest>();
                });
                
                var iMapper = config.CreateMapper();
                var gameRequest = iMapper.Map<RequestDto, GameRequest>(requestDto);
                //Create signature
                gameRequest = Utilities.CreateSignature(gameRequest, RequestType.Initiate);
                //Unique reference ID
                gameRequest.referenceId = Guid.NewGuid().ToString();
                try
                {
                    //Add request into database
                    _unitOfWork.GameRepository.Insert(gameRequest);

                    throw e;
                }
                

                #region Call Razer initiate

                HttpResponseMessage response = null;
                try
                {
                    response = await Utilities.CallRazer(gameRequest, "purchaseinitiation");
                }

                //Read response
                var htmlResponse = await response.Content.ReadAsStringAsync();

                var gameResponse = JsonConvert.DeserializeObject<GameResponse>(htmlResponse);
                //Adding response into database
                _unitOfWork.GameResponseRepository.Insert(gameResponse);
                
                if (gameResponse.initiationResultCode == "00")
                {
                    //Create signature
                    var gameConfirmRequest = Utilities.CreateSignature(gameRequest, RequestType.Confirm);
                }
                #endregion
                await _unitOfWork.SaveAsync();

                var gameConfirmResponse = Mapper.Map<RequestDto, GameConfirmResponse>(requestDto);
                scope.Complete();
                
                return gameConfirmResponse;
            }
        }

        
        public enum RequestType
        {
            Initiate = 0,
            Confirm = 1
            
        }

    }
}

How can I implement DI with Unity? Where to put configuration ?

//Transform DTO into GameRequest for calling Razer Initiate
var config = new MapperConfiguration(cfg =>
{
    cfg.CreateMap<RequestDto, GameRequest>();
    cfg.CreateMap<GameRequest, GameConfirmRequest>();
    cfg.CreateMap<GameConfirmResponse, GameConfirmResponseDto>();
    cfg.CreateMap<Coupon, CouponDto>();
});

var iMapper = config.CreateMapper();
var gameRequest = iMapper.Map<RequestDto, GameRequest>(requestDto);
