映射枚举类具有相同枚举类型

Question

说我有以下定义一个类的属性：

public class DestinationOuter 
{ 
    public string Name { get; set; } 
    public int Age { get; set; } 
    public List<DestinationInner> Siblings { get; set; } 
} 

public class DestinationInner 
{ 
    public string Name { get; set; } 
    public RelationEnum Relation { get; set; } 
} 

而且说我有一个源类型：

public class SourceSiblings 
{ 
    public string Name { get; set; } 
    public RelationEnum Relation { get; set; } 
} 

随着AutoMapper我可以很容易地创建一个配置，从SourceSiblings到DestinationInner的映射，让我来做这样的映射：

SourceSiblings[] brothers = { ... }; 
DestinationOuter dest = new DestinationOuter(); 

Mapper.Map(brothers, dest.Siblings); 

但我想要做的是直接从SourceSiblings到DestinationOuter。在这种情况下，DestinationOuter中的名称和年龄属性在映射中将被忽略，但想法是SourceSiblings将映射到DestinationOuter.Siblings。使用上面的对象声明，我希望能够做到：

Mapper.Map(brothers, dest); 

我不知道如何让这个工作。我可以设置的配置，像这样：

CreateMap<IEnumerable<SourceSiblings>, DestinationOuter>(); 

但是，这并不做任何事情。好像我需要能够这样说：

CreateMap<IEnumerable<SourceSiblings>, DestinationOuter>() 
     .ForMember(dest => dest.Siblings, 
        opt => opt.MapFrom(src => src)); 

虽然上面的编译，Mapper.Map实际上并不映射值。

此代码似乎适用于我，但它几乎是你所说的没有做任何事情。

internal class Program 
{ 
    private static void Main(string[] args) 
    { 
     SourceSiblings[] brothers = { 
             new SourceSiblings {Name = "A", Relation = 1}, 
             new SourceSiblings {Name = "B", Relation = 2} 
            }; 
     var dest = new DestinationOuter(); 

     Mapper.CreateMap<SourceSiblings, DestinationInner>(); 

     Mapper.CreateMap<IEnumerable<SourceSiblings>, DestinationOuter>() 
      .ForMember(d => d.Name, opt => opt.Ignore()) 
      .ForMember(d => d.Age, opt => opt.Ignore()) 
      .ForMember(d => d.Siblings, opt => opt.MapFrom(s => s)); 

     Mapper.Map(brothers, dest); 
     Console.Write(dest.Siblings.Count); 
     Console.ReadLine(); 
    } 
} 

public class DestinationOuter 
{ 
    public string Name { get; set; } 
    public int Age { get; set; } 
    public List<DestinationInner> Siblings { get; set; } 
} 

public class DestinationInner 
{ 
    public string Name { get; set; } 
    public int Relation { get; set; } 
} 

public class SourceSiblings 
{ 
    public string Name { get; set; } 
    public int Relation { get; set; } 
}
