鉴于以下来源:
public class SourceBase { public string TheString { get; set; } }
public class SourceDerived : SourceBase { }
和目的地:
public class DestBase { public string MyString { get; set; } }
public class DestDerived : DestBase { }
这个映射:
CreateMap<SourceBase, DestBase>()
.ForMember(dest => dest.MyString, o => o.MapFrom(x => x.TheString))
.Include<SourceDerived, DestDerived>();
CreateMap<SourceDerived, DestDerived>();
Mapper.AssertConfigurationIsValid(); // Exception is thrown here
但是,这会给出一个映射错误,指出MyString未映射到DestDerived。是什么赋予了?我是否真的需要在所有派生类型中重复基类属性的映射(我的实际代码中确实有多个子类)。
编辑:
确切的异常是无法映射DestDerived的以下1个属性:MyString。在DestDerived 上添加自定义映射表达式,忽略或重命名该属性。

如果您在下面的代码中声明它(使用AutoMapper 1.1.0.188),它可以正常工作。我不确定这是否能解决你的问题。
var result = Mapper.CreateMap<SourceBase, DestBase>()
.ForMember(dest => dest.MyString, o => o.MapFrom(x => x.TheString));
//.Include<SourceDerived, DestDerived>();
Mapper.CreateMap<SourceDerived, DestDerived>();
var source = new SourceDerived();
var destDerived = new DestDerived();
source.TheString = "teststring";
var mapResult = Mapper.Map<SourceBase, DestBase>(source, destDerived).MyString;
Console.WriteLine(mapResult);
