Episerver and Apptus illustration

Episerver CMS + AutoMapper

Published:

Here is a short example of how to properly setup AutoMapper (opens new window) 5.1 in Episerver CMS (opens new window) 9 with dependency injection.

# Configuration

Start by installing nuget package AutoMapper.

Create a class “AutoMapperConfig” in the “Infrastructure”-folder. (Where Config files are located.)

public static class AutoMapperConfig
{
    public static IMapper CreateIMapper()
    {
        var mapperConfiguration = new MapperConfiguration(cfg => cfg.AddProfiles(System.Reflection.Assembly.GetExecutingAssembly()));
        return mapperConfiguration.CreateMapper();
    }
}

This will “automagicaly” load all classes in project with base class “AutoMapper.Profiles”

Add this line to the ConfigureContainer Method in DependencyResolverInitialization class.

private static void ConfigureContainer(ConfigurationExpression container)
{
    ...
    container.For<AutoMapper.IMapper>().Use(AutoMapperConfig.CreateIMapper());
    ...
}

Simple AutoMapper profile …that will be loaded automagicaly.

public class ModelMapping : Profile
{
    public ModelMapping()
    {
        CreateMap<ModelDto, SiteModel>()
            .ForMember(dest => dest.Text, opt => opt.MapFrom(src => src.Value));
    }
}

Simple PageController using IMapper

public class SimplePageController : PageController<SimplePage>
{
    private readonly AutoMapper.IMapper _mapper;
    public SearchController(AutoMapper.IMapper mapper)
    {
        _mapper = mapper;
    }
    public ActionResult Index(SimplePage currentPage)
    {
        var viewModel = new SimplePageViewModel(currentPage);
        viewModel.SiteModel = _mapper.Map<SiteModel>( /* insert modelDto */ )
        return View(viewModel)
    }
}

Finish! I’ve been using AutoMapper for a few weeks now and it has shown it self to be really useful. Definitely a tool worth some time to get to know!
