How to add AutoMapper to DI in .Net core 2.0 Console Application

Question

I try to use AutoMapper in my .Net Core 2.0 Console Application. My class looks like this:

public class AutoGetCurrency
{
    private readonly IMapper mapper         


        

Answer 1

Install the 'AutoMapper' and 'Microsoft.Extensions.DependencyInjection' package from NuGet.

Implement User and UserDTO class for mapping from User to UserDTO:

public class User
{
    public int Id { get; set; }
    public string Name { get; set; }
}
public class UserDTO
{
    public int Id { get; set; }
    public string Name { get; set; }
}

Implement an interface and a class for doing Mapping operation as follows(don't forget using AutoMapper):

public interface ICustomMapper
{
    T MapUserToUserDTO();
}
public class CustomMapper : ICustomMapper
{
    private readonly IMapper mapper;
    public CustomMapper(IMapper mapper) =>
        this.mapper = mapper;
    public UserDTO MapUserToUserDTO()
    {
        User user = new User()
        {
           Id = 5,
           Name = "Iman"
        };
        UserDTO userDTO = mapper.Map(user);
        return userDTO;
    }
}

After that create a RegisterServices method for doing Dependency Injection in your project and a DisposeServices method for disposing of the service provider.

using AutoMapper;
using Microsoft.Extensions.DependencyInjection;

namespace AutoMapperProject
{
    class Program
    {
        private static IServiceProvider _serviceProvider;
        static void Main(string[] args)
        {
            RegisterServices();
            ICustomMapper service = 
            _serviceProvider.GetService>();
            UserDTO userDTO = service.MapUserToUserDTO();
            DisposeServices();
            Console.WriteLine("Hello AutoMapper!");
        }
        private static void RegisterServices()
        {
            var collection = new ServiceCollection();
            collection.AddAutoMapper(typeof(Program));
            collection.AddScoped, CustomMapper>();
            // ...
            // Add other services
            // ...
            _serviceProvider = collection.BuildServiceProvider();
        }
        private static void DisposeServices()
        {
           if (_serviceProvider == null)
           {
              return;
           }
           if (_serviceProvider is IDisposable)
           {
              ((IDisposable)_serviceProvider).Dispose();
           }
        }
    }
}

Good Luck
