使用自動映射器將多個對象映射到一個對象

Question

是否可以使用自動映射器將一個對象映射到多個對象？我知道有可能以相反的方式做here。

一種方式做到這一點：

Mapper.CreateMap<MAINSource, MAINDest>() 
    .ForMember(dest => dest.Inner1, expression => expression.ResolveUsing(source1 => source1.Inner1)) 
    .ForMember(dest => dest.Inner2, expression => expression.ResolveUsing(source1 => source1.Inner2)); 


Mapper.CreateMap<Source1, Dest1>() 
    .ForMember(dest => dest.NumValue, expression => expression.ResolveUsing(source1 => source1.NumValue)); 
Mapper.CreateMap<Source1, Dest2>() 
    .ForMember(dest => dest.StringValue, expression => expression.ResolveUsing(source1 => source1.StringValue)); 

完整的示例：

public class Source1 
{ 
    public int NumValue { get; set; } 
    public string StringValue { get; set; } 
} 

public class MAINSource 
{ 
    public Source1 Inner1 { get; set; } 
    public Source1 Inner2 { get; set; } 
} 

public class Dest1 
{ 
    public int NumValue { get; set; } 
} 

public class Dest2 
{ 
    public string StringValue { get; set; } 
} 

public class MAINDest 
{ 
    public Dest1 Inner1 { get; set; } 
    public Dest2 Inner2 { get; set; } 
} 


Mapper.CreateMap<MAINSource, MAINDest>() 
    .ForMember(dest => dest.Inner1, expression => expression.ResolveUsing(source1 => source1.Inner1)) 
    .ForMember(dest => dest.Inner2, expression => expression.ResolveUsing(source1 => source1.Inner2)); 


Mapper.CreateMap<Source1, Dest1>() 
    .ForMember(dest => dest.NumValue, expression => expression.ResolveUsing(source1 => source1.NumValue)); 
Mapper.CreateMap<Source1, Dest2>() 
    .ForMember(dest => dest.StringValue, expression => expression.ResolveUsing(source1 => source1.StringValue)); 

var innerSource = new Source1 {NumValue = 1, StringValue = "supervalue"}; 
var mainSource = new MAINSource 
{ 
    Inner1 = innerSource, 
    Inner2 = innerSource 
}; 


var destination = Mapper.Map<MAINSource, MAINDest>(mainSource); 

destination.Inner1.NumValue.ShouldEqual(1); 
destination.Inner2.StringValue.ShouldEqual("supervalue");
