如何使用 AutoMapper 将具有子实体的实体提取到单视图模型？

Question

我有以下实体：

public class ClassA
{
    public int Id{get;set;}
    public string Property1{get;set;}
    public string Property2{get;set;}        
    .
    .
    public string Property(n){get;set;}
    public ClassB Item{get;set;}
}

public class ClassB
{
    public int Id{get;set;}
    public string Property(n+1){get;set;}
    public string Property(n+2){get;set;}
    .
    .
    public string Property(n+m){get;set;}
}

我的 ViewModel 是：

public class MyViewModel
{
  public string Property1{get;set;}
  public string Property2{get;set;}
  .
  .
  public string Property(n+m){get;set;}
}

如何使用 AutoMapper 将具有子实体“ClassB”的类“ClassA”映射到“MyViewModel”？

Answer 1

选项#1：

Mapper.CreateMap<ClassA, MyViewModel>();
Mapper.CreateMap<ClassB, MyViewModel>()
    .ForMember(dest => dest.Id, opt => opt.Ignore());

var vm = Mapper.Map<MyViewModel>(classA);
Mapper.Map<ClassB, MyViewModel>(classA.Item, vm);

选项 #2：

Mapper.CreateMap<ClassA, MyViewModel>()
    .ForMember(dest => dest.Property(n+1), opt => opt.MapFrom(source => Item.Property(n+1)))
    .ForMember(...); //for each of ClassB property

var vm = Mapper.Map<MyViewModel>(classA);
