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.

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!

默认情况下，AutoMapper使用目标类型来验证成员，但您可以通过使用MemberList跳过验证。没有选择。

var configuration = new MapperConfiguration(cfg =>
  cfg.CreateMap<Source2, Destination2>(MemberList.None);
);

我知道这是个老问题，但是@jmoerdyk 在你的问题中:

如何在配置文件中的链式creatatemap()表达式中使用它?

你可以像这样在Profile中使用这个答案

this.IgnoreUnmapped();
CreateMap<TSource, Tdestination>(MemberList.Destination)
.ForMember(dest => dest.SomeProp, opt => opt.MapFrom(src => src.OtherProp));

版本12 这是一个非常糟糕的代码，但它解决了紧急工作。

      CreateMap<RepairPutRequest, Repair>(MemberList.None) 
                .ForAbdusselamMember(x => x.ClosedLostTimeId, y => y.MapFrom(z => z.ClosedLostTimeId))
                .ForAbdusselamMember(x => x.Explanation, y => y.MapFrom(z => z.Explanation)).IgnoreUnmapped()
                ;
