如何使用 Automapper 将 class 映射到子 class？

Question

如果我有 class:

public class MainClass
{
   public string StringA {get; set;}
   public string StringB {get; set;}
   public string StringC {get; set;}
   public string Candy {get; set; }
}

现在我想将其映射到另一个 class

public class NewClass
{
   public string StringA {get; set;}
   public string StringB {get; set;}
   public string StringC {get; set;}
   public CandyObj Candy {get; set; }
}

而 CandyObj 就是：

public class CandyObj 
{
   public string CandyID {get; set;}
   public string CandyName {get; set;}
}

如何处理 NewClass 中 CandyObj 的映射？

我试过这条路：

    var config = new MapperConfiguration(c =>
    {
        c.CreateMap<MainClass, NewClass>()
            .ForMember(x => x.Candy.CandyID, m => m.MapFrom(a => a.Candy))
            .ForMember(x => x.Candy.CandyName, m => m.MapFrom(a => a.Candy));
    });

但是我得到了"Expression 'x => x.Candy.CandyID' must resolve to top-level member and not any child object's properties."

我还是 AutoMapper 的新手，所以任何指导都将不胜感激。

我发现我可以这样做：

        c.CreateMap<MainClass, NewClass>()
            .ForMember(x => x.Candy,
                       opts => opts.MapFrom(
                           src => new CandyObj
                           {
                               CandyID = src.Candy,
                               CandyName = src.Candy
                           }
                       ));
