Automapper：轉換JSON列出對象

Question

源對象（JSON，使用JSON.NET如果它事項）：

{ 
    "conum" : 1001, 
    "name" : "CLN Industries Corporation", 
    "agencyName" : "Murphy, Holmes & Associates, LLC", 
    "sAA" : [{ 
      "code" : 247, 
      "description" : "Mechanic\u0027s lien - Bond to Discharge - Fixed penalty - where principal has posted Performance and Pa" 
     }, { 
      "code" : 277, 
      "description" : "Mechanic\u0027s lien - Bond to Discharge - Open Penalty - where principal has posted Performance and Paym" 
     }, { 
      "code" : 505, 
      "description" : "Indemnity Bonds - Contractor\u0027s Indemnity Against Damages where there is a performance bond and addit" 
     } 
    ] 
} 

目標對象（C＃）：

public class CorporateRatesInfo 
{ 
    public string Conum { get; set; } 
    public string Name { get; set; } 
    public string AgencyName { get; set; } 
    public List<SaaCode> SaaCodes { get; set; } 
} 

public class SaaCode 
{ 
    public string Code { get; set; } 
    public string Description { get; set; } 
} 

Automapper配置和映射：

var config = new MapperConfiguration(cfg => 
{ 
    cfg.CreateMap<JObject, CorporateRatesInfo>(); 
    cfg.AddProfile<CorporateRatesProfile>(); 
}); 

//config.AssertConfigurationIsValid(); 
_mapper = config.CreateMapper(); 


public class CorporateRatesProfile : Profile 
{ 
    protected override void Configure() 
    { 
     CreateMap<JObject, CorporateRatesInfo>() 
      .ForMember("SaaCodes", cfg => { cfg.MapFrom(jo => jo["sAA"]); }) 
      .ForMember("Conum", cfg => { cfg.MapFrom(jo => jo["conum"]); }) 
      .ForMember("Name", cfg => { cfg.MapFrom(jo => jo["name"]); }) 
      .ForMember("AgencyName", cfg => { cfg.MapFrom(jo => jo["agencyName"]); }); 
    } 
} 

除了SaaCodes轉換，其中Automapper將每個條目轉換爲空的SaaCode對象ct（所有屬性都設爲null）。

如何告訴automapper如何將該JSON字段中的項目轉換爲目標類型？

嘗試了這一點 -

public class CorporateRatesInfo 
{ 
    public string Conum { get; set; } 
    public string Name { get; set; } 
    public string AgencyName { get; set; } 
    public List<SaaCode> SaaCodes { get; set; } 
} 

public class SaaCode 
{ 
    public string Code { get; set; } 
    public string Description { get; set; } 
} 

public class CorporateRatesProfile : Profile 
{ 
    protected override void Configure() 
    { 
     CreateMap<JObject, SaaCode>() 
      .ForMember("Code", cfg => { cfg.MapFrom(jo => jo["code"]); }) 
      .ForMember("Description", cfg => { cfg.MapFrom(jo => jo["description"]); }); 

     CreateMap<JObject, CorporateRatesInfo>() 
      .ForMember("SaaCodes", cfg => { cfg.MapFrom(jo => jo["sAA"]); }) 
      .ForMember("Conum", cfg => { cfg.MapFrom(jo => jo["conum"]); }) 
      .ForMember("Name", cfg => { cfg.MapFrom(jo => jo["name"]); }) 
      .ForMember("AgencyName", cfg => { cfg.MapFrom(jo => jo["agencyName"]); }); 


    } 
} 

class Program 
{ 
    static void Main(string[] args) 
    { 

     var config = new MapperConfiguration(cfg => 
     { 
      cfg.CreateMap<JObject, CorporateRatesInfo>(); 
      cfg.AddProfile<CorporateRatesProfile>(); 
     }); 

     //config.AssertConfigurationIsValid(); 
     var mapper = config.CreateMapper(); 

     var jsonText = @" 
          { 
           ""conum"" : 1001, 
           ""name"" : ""CLN Industries Corporation"", 
           ""agencyName"" : ""Murphy, Holmes & Associates, LLC"", 
           ""sAA"" : [{ 
             ""code"" : 247, 
             ""description"" : ""Mechanic\u0027s lien - Bond to Discharge - Fixed penalty - where principal has posted Performance and Pa"" 
            }, { 
             ""code"" : 277, 
             ""description"" : ""Mechanic\u0027s lien - Bond to Discharge - Open Penalty - where principal has posted Performance and Paym"" 
            }, { 
             ""code"" : 505, 
             ""description"" : ""Indemnity Bonds - Contractor\u0027s Indemnity Against Damages where there is a performance bond and addit"" 
            } 
           ] 
          } 
         "; 

     var jsonoObj = JObject.Parse(jsonText); 

     CorporateRatesInfo dto = mapper.Map<CorporateRatesInfo>(jsonoObj); 



    } 
}
