如何使用自動映射器將單個對象屬性映射到複雜類型的對象數組

Question

我得到了如下的類結構，並且創建了映射結構，但它不像預期的那樣工作。

public class ResponseHeader 
{ 
    public ResHeader ResHeader { get; set; } 
} 

public class ResHeader 
{ 
    public ServiceResStatus ServiceResStatus { get; set; } 

    public Error[] Errors { get; set; } 
} 

public class Error 
{ 
    public string ErrorCode { get; set; } 

    public string ErrorDesc { get; set; } 

    public string Source { get; set; } 
} 

public class ServiceResStatus 
{ 
    public string ServiceResCode { get; set; } 

    public string ServiceResDesc { get; set; } 

    public System.DateTime ServiceRespDateTime { get; set; } 

    public string ServiceUniqueRefNo { get; set; } 
} 


public class ExceptionInformation 
{ 
    public string Code { get; set; } 
    public string Description { get; set; } 
    public string Source { get; set; } 
} 

我想映射ExceptionInformation屬性到ResponseHeader。我總是得到ResponseHeader dto爲null。

var config = new MapperConfiguration(cfg => 
     { 

      cfg.CreateMap<ExceptionInformation, ResponseHeader>(); 


      cfg.CreateMap<ExceptionInformation, ResHeader>() 
       .ForMember(d => d.Errors, opts => opts.ResolveUsing(src => new Error() {ErrorCode = src.Code})) 
       .ForMember(d => d.Errors, opts => opts.ResolveUsing(src => new Error() {ErrorDesc = src.Description})) 
       .ForMember(d => d.Errors, opts => opts.ResolveUsing(src => new Error() {Source = src.Code})) 
       .ForMember(d => d.ServiceResStatus, opts => opts.Ignore()); 

      cfg.CreateMap<ExceptionInformation, ServiceResStatus>() 
       .ForMember(d => d.ServiceResCode, opts => opts.MapFrom(src => src.Code)) 
       .ForMember(d => d.ServiceResDesc, opts => opts.MapFrom(src => src.Description)) 
       .ForMember(d => d.ServiceRespDateTime, opts => opts.MapFrom(src => DateTime.Now)) 
       .ForMember(d => d.ServiceUniqueRefNo, opts => opts.Ignore()); 

     }); 


     var mapper = config.CreateMapper(); 

     var info = new ExceptionInformation() 
     { 
      Code = "ERR01", 
      Description = "Error", 
      Source = "Oven" 

     }; 


     ResponseHeader dto = mapper.Map<ResponseHeader>(info); 

任何工作解決方案讚賞。

我想出瞭解決方案來解決您的問題。這裏是代碼片段

public class ResponseHeader 
{ 
    public ResHeader ResHeader { get; set; } 
} 

public class ResHeader 
{ 
    public ServiceResStatus ServiceResStatus { get; set; } 

    public Error[] Errors { get; set; } 
} 

public class Error 
{ 
    public string Code { get; set; } 

    public string Description { get; set; } 

    public string Source { get; set; } 
} 

public class ServiceResStatus 
{ 
    public string ServiceResCode { get; set; } 

    public string ServiceResDesc { get; set; } 

    public System.DateTime ServiceRespDateTime { get; set; } 

    public string ServiceUniqueRefNo { get; set; } 
} 


public class ExceptionInformation 
{ 
    public string Code { get; set; } 
    public string Description { get; set; } 
    public string Source { get; set; } 
} 

class Program 
{ 
    static void Main(string[] args) 
    { 
     var config = new MapperConfiguration(cfg => 
     { 
      cfg.CreateMap<ExceptionInformation, Error>(); 

      cfg.CreateMap<ExceptionInformation, ResHeader>() 
       .ForMember(d => d.Errors, opts => opts.MapFrom(src => new[] {src})) 
       .ForMember(d => d.ServiceResStatus, opts => opts.Ignore()); 

      cfg.CreateMap<ExceptionInformation, ServiceResStatus>() 
       .ForMember(d => d.ServiceResCode, opts => opts.MapFrom(src => src.Code)) 
       .ForMember(d => d.ServiceResDesc, opts => opts.MapFrom(src => src.Description)) 
       .ForMember(d => d.ServiceRespDateTime, opts => opts.MapFrom(src => DateTime.Now)) 
       .ForMember(d => d.ServiceUniqueRefNo, opts => opts.Ignore()); 

      cfg.CreateMap<ExceptionInformation, ServiceResStatus>() 
       .ForMember(d => d.ServiceResCode, opts => opts.MapFrom(src => src.Code)) 
       .ForMember(d => d.ServiceResDesc, opts => opts.MapFrom(src => src.Description)) 
       .ForMember(d => d.ServiceRespDateTime, opts => opts.MapFrom(src => DateTime.Now)) 
       .ForMember(d => d.ServiceUniqueRefNo, opts => opts.Ignore()); 

      cfg.CreateMap<ExceptionInformation, ResponseHeader>() 
       .ForMember(des => des.ResHeader, opt => opt.MapFrom(src => new ResHeader() 
       { 
        Errors = new Error[1] { new Error() {Code = src.Code, Description = src.Description, Source = src.Source }}, 
        ServiceResStatus = new ServiceResStatus() { ServiceResCode = src.Code, ServiceResDesc = src.Description, ServiceRespDateTime = DateTime.Now, ServiceUniqueRefNo = null} 
       })); 
     }); 


     var mapper = config.CreateMapper(); 

     var info = new ExceptionInformation() 
     { 
      Code = "ERR01", 
      Description = "Error", 
      Source = "Oven" 

     }; 

     var dto1 = mapper.Map<ExceptionInformation, Error>(info); 
     var dto2 = mapper.Map<ExceptionInformation, ResHeader>(info); 
     var dto3 = mapper.Map<ExceptionInformation, ServiceResStatus>(info); 
     var dto4 = mapper.Map<ExceptionInformation, ResponseHeader>(info); 

     //Put a check point in cole readline and verify objects dto1, dto2, dto3 and dto4 
     Console.ReadLine(); 
    } 
}
