c #automapper字典到字典

Question

我试图将Superhero模型自动映射到Supervillan模型,每个模型都有类似的字典声明:

超级英雄:

public class Superheroes {
    public Dictionary<string, SomeHero>> SuperNumber {get; set;}
}

public class SomeHero {
 // unique properties
}

Supervillan:

public class Supervillans {
    public Dictionary<string, SomeVillan>> SuperNumber {get; set;}
}

public class SomeVillan {
 // unique properties
}

我尝试在其他类似的线程中遵循建议,但没有成功.这是我最近的尝试,执行失败:

CreateMap<KeyValuePair<string, Superheroes>, KeyValuePair<string, Supervillans>>(); 

如何将我的超级英雄SuperNumber字典映射到我的Supervillan SuperNumber字典？

注意:SomeHero/SomeVillan模型将具有独特的属性,但我对此问题并不关心它们.

它应该开箱即用。字典不需要显式配置映射：Dynamic 和 ExpandoObjects。如果属性与我的示例中相同，则类也相同。

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

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

public class ClassA
{
    public Dictionary<string, ObjA> Vals { get; set; } = new Dictionary<string, ObjA>{
        {"a", new ObjA(){ Name = "A", } },
        {"b", new ObjA(){ Name = "B", } },
        {"c", new ObjA(){ Name = "C", } },
        {"d", new ObjA(){ Name = "D", } },
    };
}

public class ClassB
{
    public Dictionary<string, ObjB> Vals { get; set; } = new Dictionary<string, ObjB>{
        {"a", new ObjB(){ Name = "A", } },
        {"b", new ObjB(){ Name = "B", } },
        {"c", new ObjB(){ Name = "C", } },
        {"d", new ObjB(){ Name = "D", } },
    };
}

如果您随后按如下方式使用自动映射器，映射应该会自动工作。

var obja = new ClassA();
var objb = new ClassB();
var config = new MapperConfiguration(cfg => {});
var mapper = config.CreateMapper();
var obj = mapper.Map<ClassB>(obja);
var obj2 = mapper.Map<ClassA>(objb);

如果你想对类的映射进行硬编码，应该这样做：

var config = new MapperConfiguration(cfg => {
    cfg.CreateMap<ClassA, ClassB>().ReverseMap();
});
