AutoMapper-将平面对象映射到复杂对象

Question

我有这些型号：

class Source
{
String A;
String B;
String C;
String D;
}
class Destination
{
String A;
String B;
Another another;
Other other;
}
class Other
{
String C;
AnotherOne Another;
}
class AnotherOne
{
String D;
}

我想将Source模型映射到Destination及其子模型。第一种尝试使用AutoMapper的方法。那么这有可能吗？还是手动完成此作业更好？

Answer 1

解决方案1：使用ForPath

var config = new MapperConfiguration(cfg =>
{
cfg.CreateMap<Source, AnotherOne>();

cfg.CreateMap<Source, Other>()
.ForPath(dest => dest.Another, opt => opt.MapFrom(src => src));

cfg.CreateMap<Source, Destination>()
.ForPath(dest => dest.other, opt => opt.MapFrom(src => src));
});

解决方案2：使用IncludeMembers来压平，使用ReverseMap来显式创建反向映射

var config = new MapperConfiguration(cfg =>
{           
cfg.CreateMap<Source, AnotherOne>()
.ReverseMap();

cfg.CreateMap<Other, Source>()
.IncludeMembers(src => src.Another)
.ReverseMap();

cfg.CreateMap<Destination, Source>()
.IncludeMembers(src => src.other)
.ReverseMap();
});
