映射枚舉類具有相同枚舉類型

Question

說我有以下定義一個類的屬性：

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; } 
} 

而且說我有一個源類型：

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

隨着AutoMapper我可以很容易地創建一個配置，從SourceSiblings到DestinationInner的映射，讓我來做這樣的映射：

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

Mapper.Map(brothers, dest.Siblings); 

但我想要做的是直接從SourceSiblings到DestinationOuter。在這種情況下，DestinationOuter中的名稱和年齡屬性在映射中將被忽略，但想法是SourceSiblings將映射到DestinationOuter.Siblings。使用上面的對象聲明，我希望能夠做到：

Mapper.Map(brothers, dest); 

我不知道如何讓這個工作。我可以設置的配置，像這樣：

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

但是，這並不做任何事情。好像我需要能夠這樣說：

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

雖然上面的編譯，Mapper.Map實際上並不映射值。

Answer 1

此代碼似乎適用於我，但它幾乎是你所說的沒有做任何事情。

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; } 
}
