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!

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();
});

在3.3.1版本中，您可以使用IgnoreAllPropertiesWithAnInaccessibleSetter()或IgnoreAllSourcePropertiesWithAnInaccessibleSetter()方法。

更新:这个答案对那些使用最新版本的Automapper不再有用，因为ForAllOtherMembers已经在Automapper 11中被删除了。

AutoMapper的5.0.0-beta-1版本引入了ForAllOtherMembers扩展方法，所以你现在可以这样做:

CreateMap<Source, Destination>()
    .ForMember(d => d.Text, o => o.MapFrom(s => s.Name))
    .ForMember(d => d.Value, o => o.MapFrom(s => s.Id))
    .ForAllOtherMembers(opts => opts.Ignore());

请注意，显式映射每个属性有一个好处，因为当您忘记映射某个属性时，您永远不会遇到映射失败的问题。

也许在您的情况下，明智的做法是忽略所有其他成员，并添加一个TODO来返回，并在该类的更改频率稳定下来后显式地显示这些成员。

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()
                ;

        public static Dictionary<string, List<string>> list = new Dictionary<string, List<string>>();

             var sourceType = typeof(TSource);
            var destinationType = typeof(TDestination);
            var key =$"{sourceType.FullName}__||__{destinationType.FullName}"   ;
            var t = list[key];
            foreach (var item in destinationType.GetProperties())
            {
                if (!t.Contains(item.Name)) {
                    expression.ForMember(item.Name, x => x.Ignore());
                    }
            }
            return expression;
        }

            var destinationType = typeof(TDestination);

            var memberInfo = ReflectionHelper.FindProperty(destinationMember);

            list[key].Add(memberInfo.Name);
            return expression;
        }
          
    }
