[Solved] Generic class of one type to another type in auto mapper

by


For Mapper.Map<PagedList<CasteModel>>(result);, you need to initialize Mapper like below in Startup.cs 

    public void ConfigureServices(IServiceCollection services)
    {
        Mapper.Initialize(cfg =>
        {
            cfg.AddProfile<AppProfile>();
        });
        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
    }

But, it it recommended to use Dependence Injection to resolve Mapper.

  1. Install Package AutoMapper.Extensions.Microsoft.DependencyInjection

  2. Startup.cs 

    public void ConfigureServices(IServiceCollection services)
{
    services.AddAutoMapper(typeof(Startup));
    services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
}

  3. UseCase 

    public class ValuesController : ControllerBase
{
    private readonly IMapper _mapper;
    public ValuesController(IMapper mapper)
    {
        _mapper = mapper;
    }
    // GET api/values
    [HttpGet]
    public ActionResult<IEnumerable<string>> Get()
    {
        PagedList<Caste> result = new PagedList<Caste>
        {
            Items = new List<Caste> { new Caste { Id = 7, CasteCode = "" } },
            TotalItems = 1
        };

        var pagedListOfDtos = _mapper.Map<PagedList<CasteModel>>(result);
        return new string[] { "value1", "value2" };
    }       
}
