Question

这是我的View Model类：

public class EntryViewModel { }

在我的代码中，根据某个参数，我试图将其映射到：

基类：

public class Entry { }

或三个子类：

public class VacationEntry : Entry { }

public class WorkEntry : Entry { }

public class SickLeaveEntry : Entry { }

以下是我创建的地图：

Mapper.CreateMap<Entry, EntryViewModel>(); 

Mapper.CreateMap<EntryViewModel, Entry>();

Mapper.CreateMap<EntryViewModel, VacationEntry >()
  .IncludeBase<EntryViewModel, Entry>();

Mapper.CreateMap<EntryViewModel, WorkEntry >()
  .IncludeBase<EntryViewModel, Entry>();

Mapper.CreateMap<EntryViewModel, SickLeaveEntry >()
  .IncludeBase<EntryViewModel, Entry>();

Mapper.AssertConfigurationIsValid();

现在，当我将View Model映射到Sub Class时，一切正常 - Mapper返回了我期待的类：

var entry = new EntryViewModel();
Entry result = Mapper.Map(entry, entry.GetType(), typeof(VacationEntry)) as Entry // result is type of VacationEntry

但是在尝试将ViewModel映射到Base Class时，我的结果是Sub Classes的最后一个CreatedMap的类型 - 在本例中是SickLeaveEntry：

var entry = new EntryViewModel();
Entry result = Mapper.Map(entry, entry.GetType(), typeof(Entry)) as Entry // result is type of SickLeaveEntry, but I was expecting Entry

有没有办法从AutoMapper获取基类？

将ViewModel映射到Base类时，automapper返回Sub Class
