目标对象(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; }
}
自动配置和映射:
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转换之外,一切都有效,其中Automapper将每个条目转换为空的SaaCode对象(所有属性都设置为null).
如何/在何处告诉automapper如何将该JSON字段中的项目转换为其目标类型?
解决方法:
试试这个 –
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"]); });
}
}
