Question

我有班级课程：

{
"operations": [
  {
    "method": "GET", 
    "path": "/reports/campaign_id/email-activity",
   "operation_id" : "123"
  }
]
}

如何创建像

这样的映射

class A
{
    public string str1 { get; set; }
    public string str2 { get; set; }
    public string str3 { get; set; }
}

class B
{
    public string bstr1 { get; set; }
    public string bstr2 { get; set; }
}

class C
{
    public string cstr1 { get; set; }
    public IEnumerable<B> barr1 { get; set; }
}

简单的说明如何将对象映射到目标中数组的第一项。

Answer 1

您可以执行以下操作：

Mapper.CreateMap<A, B>()
      .ForMember(dest => dest.bstr1, exp => exp.MapFrom(src => src.str2))
      .ForMember(dest => dest.bstr2, exp => exp.MapFrom(src => src.str3));

Mapper.CreateMap<A, C>()
      .ForMember(dest => dest.cstr1, exp => exp.MapFrom(scc => scc.str1))
      .ForMember(dest => dest.barr1, exp => exp.ResolveUsing<AToBCollectionResolver>());

AToBCollectionResolver：

class AToBCollectionResolver : ValueResolver<A, IEnumerable<B>>
{
    protected override IEnumerable<B> ResolveCore(A source)
    {
        return new[] { Mapper.Map<B>(source)};
    }
}
