无法在 AutoMapper 中配置 ReverseMap

Question

我是 AutoMapper 新手。我的映射没有按预期工作，我确定我做错了什么但无法弄清楚。抱歉，如果这个问题令人困惑，但我会尽力弄清楚。假设我们有三个类:

public class Person
{
    public ContactInfo1 Contact { get; set; }
}

public class ContactInfo1
{
    public string Name { get; set; }
}

public class ContactInfo2
{
    public string AnotherName { get; set; }
}

现在，我想设置我的映射，以便 ContactInfo1 可以映射到 ContactInfo2 或从 ContactInfo2 映射。然后我希望能够映射 Person1 -> ContactInfo2（这可能看起来很奇怪，但无论如何我都需要这样做）。我尝试了以下映射配置：

var autoMapperConfig = new AutoMapper.MapperConfiguration(cfg =>
{
    cfg.CreateMap<ContactInfo1, ContactInfo2>()
        .ForMember(dest => dest.AnotherName, opt => opt.MapFrom(src => src.Name)).ReverseMap();
    cfg.CreateMap<ContactInfo2, Person>()
        .ForMember(dest => dest.Contact, opt => opt.MapFrom(src => src)).ReverseMap();
    });

var mapper = autoMapperConfig.CreateMapper();

对于测试数据：

var testPerson = new Person();
testPerson.Contact = new ContactInfo1() { Name = "Person1" };

我执行以下操作：

var contactInfo2Test = mapper.Map<Person, ContactInfo2>(testPerson);

这不会给我任何错误，但是 contactInfo2Test.AnotherName 是空的。请指教！谢谢。

Please note that I realize I could go:
cfg.CreateMap<Person, ContactInfo2>()
    .ForMember(dest => dest.AnotherName, opt => opt.MapFrom(src => src.Contact.Name));
Bu then I would have mapped Contact1->Contact2 all over again, and in a more complex scenario I really want to avoid that.

这是一种方法：

var autoMapperConfig = new AutoMapper.MapperConfiguration(cfg =>
{
    cfg.CreateMap<ContactInfo1, ContactInfo2>()
        .ForMember(dest => dest.AnotherName, opt => opt.MapFrom(src => src.Name))
        .ReverseMap();
    cfg.CreateMap<Person, ContactInfo2>()
        .ConstructUsing((p, ctx) => ctx.Mapper.Map<ContactInfo2>(p.Contact));
});
