AutoMapper Map 날짜/시간 객체

Question

최근에 사용자가 내 웹 사이트에 날짜를 입력하는 방법을 변경했습니다. 그것은 텍스트 상자로 사용되는 사람들이 그것을 입력하지만 의견을받은 후 사람들은 DD MM YYYY로 3 드롭 다운을 선호하는 것 같습니다. 나는 SO에서 찾은 몇 가지 코드를 사용하여 이것을 내 웹 사이트에 추가했습니다.

그것을 구현하려면 내가 주위에 잘못된 데이터 유효성 검사를받을 수있는 클래스를 생성했다, 내 클래스는 텍스트 상자 때이

public class DateSelector : ICustomMappings { 
    public DateSelector() : this(System.DateTime.MinValue) { } 
    public DateSelector(DateTime date) { 
     Year = date.Year; 
     Month = date.Month; 
     Day = date.Day; 
    } 

    [Required] 
    public int Year { get; set; } 

    [Required, Range(1, 12)] 
    public int Month { get; set; } 

    [Required, Range(1, 31)] 
    public int Day { get; set; } 

    public DateTime? DateTime { 
     get { 
      DateTime date; 
      if (!System.DateTime.TryParseExact(string.Format("{0}/{1}/{2}", Year, Month, Day), "yyyy/M/d", CultureInfo.InvariantCulture, DateTimeStyles.None, out date)) 
       return null; 
      else 
       return date; 
     } 
    } 

    public void CreateMappings(IConfiguration configuration) { 
     configuration.CreateMap<DateTime, DateSelector>() 
      .ForMember(dest=>dest.DateTime,opt=>opt.Ignore()) 
      .ForMember(dest => dest.Day, opt => opt.MapFrom(src => src.Day)) 
      .ForMember(dest => dest.Month, opt => opt.MapFrom(src => src.Month)) 
      .ForMember(dest => dest.Year, opt => opt.MapFrom(src => src.Year)); 
    } 
} 

Automapper 큰 일처럼 보이지만 지금 필자 내가 얻을 드롭 다운으로 분할 다음 오류.

이진 연산자 NotEqual은 'System.DateTime'및 'System.Object'형식에 대해 정의되지 않습니다.

DateTime을 내 수업에 매핑하려고했기 때문에 내가 어떻게 생각하니, 어떻게해야합니까?

편집 : DataSelector 클래스를 사용하는 ViewModel을 놓쳤습니다.

 public class _YoungPersonViewModel ICustomMappings { 

     public int YoungPersonId { get; set; } 
     public string FirstName { get; set; } 
     public string Surname { get; set; } 
     public string FullName { get { return FirstName + " " + Surname; } } 
     public DateSelector DateOfBirth { get; set; } 
     public IEnumerable<SelectListItem> GenderTypeList { get; set; } 

     public void CreateMappings(IConfiguration configuration) { 
      configuration.CreateMap<Entities.Models.YoungPerson, _YoungPersonViewModel>() 

       .ForMember(dest => dest.DateOfBirth, opt=>opt.MapFrom(src=>src.DateOfBirth)); 
     } 
    }

에 한번 사용 ProjectUsing :

configuration.CreateMap<DateTime, DateSelector>() 
    . ProjectUsing(src => new DateSelector(src));
