I'm trying to use Automapper to convert all my DateTimes from UTC to Local Time but i need to inject an interface into ITypeConverter... I'm receiving this error when I run the application: MissingMethodException: No parameterless constructor defined for this object.
I think that the problem is with the dependency injection code!
Anyone can help me?
UserRepository:
public class UserRepository : IUserRepository
{
private static readonly MapperConfiguration Config = new MapperConfiguration(cfg =>
{
cfg.CreateMap<User, User>();
cfg.CreateMap<DateTime?, DateTime?>().ConvertUsing<UtcToLocalConverter>();
});
public List<User> GetById(string[] ids)
{
var result = BuildQuery().Where(w => ids.Contains(w.UserName)).ToList();
var mapper = Config.CreateMapper();
return mapper.Map<List<User>>(result); // Throws error !!!
}
#region Helper
private IQueryable<User> BuildQuery()
{
return Settings.EpedDb.User;
}
#endregion
}
Converter
public class UtcToLocalConverter : ITypeConverter<DateTime?, DateTime?>
{
public UtcToLocalConverter(IBaseSettings baseClass) // I tried to inject here!!!
{
Settings = baseClass;
}
private IBaseSettings Settings { get; }
public DateTime? Convert(DateTime? source, DateTime? destination, ResolutionContext context)
{
if (source == null) return null;
var tzi = TimeZoneInfo.FindSystemTimeZoneById(Settings.UserData.TimeZone);
return TimeZoneInfo.ConvertTime(DateTime.SpecifyKind((DateTime)source, DateTimeKind.Utc), tzi);
}
}
