对于Automapper 5.0，为了跳过所有未映射的属性，你只需要放

.ForAllOtherMembers（x=>x.Ignore（））;

在你资料的最后。

例如:

internal class AccountInfoEntityToAccountDtoProfile : Profile
{
    public AccountInfoEntityToAccountDtoProfile()
    {
        CreateMap<AccountInfoEntity, AccountDto>()
           .ForMember(d => d.Id, e => e.MapFrom(s => s.BankAcctInfo.BankAcctFrom.AcctId))
           .ForAllOtherMembers(x=>x.Ignore());
    }
}

在这种情况下，只有Id字段的输出对象将被解析，所有其他将被跳过。工作就像一个魅力，似乎我们不需要任何棘手的扩展了!

我已经能够做到这一点的方式如下:

Mapper.CreateMap<SourceType, DestinationType>().ForAllMembers(opt => opt.Ignore());
Mapper.CreateMap<SourceType, DestinationType>().ForMember(/*Do explicit mapping 1 here*/);
Mapper.CreateMap<SourceType, DestinationType>().ForMember(/*Do explicit mapping 2 here*/);
...

注意:我使用的是AutoMapper v.2.0。

The only infromation about ignoring many of members is this thread - http://groups.google.com/group/automapper-users/browse_thread/thread/9928ce9f2ffa641f . I think you can use the trick used in ProvidingCommonBaseClassConfiguration to ignore common properties for similar classes. And there is no information about the "Ignore the rest" functionality. I've looked at the code before and it seems to me that will be very and very hard to add such functionality. Also you can try to use some attribute and mark with it ignored properties and add some generic/common code to ignore all marked properties.

当前(版本9)忽略目标类型中不存在的属性的解决方案是创建一个翻转映射并反转它:

var config = new MapperConfiguration(cfg => {
  cfg.CreateMap<TheActualDestinationType, TheActualSourceType>().ReverseMap();
});

我更新了Robert Schroeder对AutoMapper 4.2的答案。对于非静态映射器配置，我们不能使用mapper . getalltypemaps()，但表达式有一个对所需的TypeMap的引用:

public static IMappingExpression<TSource, TDestination> 
    IgnoreAllNonExisting<TSource, TDestination>(this IMappingExpression<TSource, TDestination> expression)
{
    foreach (var property in expression.TypeMap.GetUnmappedPropertyNames())
    {
        expression.ForMember(property, opt => opt.Ignore());
    }
    return expression;
}

对于Automapper 5.0，为了跳过所有未映射的属性，你只需要放

.ForAllOtherMembers（x=>x.Ignore（））;

例如:

internal class AccountInfoEntityToAccountDtoProfile : Profile
{
    public AccountInfoEntityToAccountDtoProfile()
    {
        CreateMap<AccountInfoEntity, AccountDto>()
           .ForMember(d => d.Id, e => e.MapFrom(s => s.BankAcctInfo.BankAcctFrom.AcctId))
           .ForAllOtherMembers(x=>x.Ignore());
    }
}
