Question

我试图忽略一些成员并对当前成员提出一些条件：

        CreateMap<UpdateProfileViewModel, UserSettingModel>()
            .ForMember(dest => dest.FirstName, opts => opts.MapFrom(src => src.FirstName))
            .ForMember(dest => dest.LastName, opts => opts.MapFrom(src => src.LastName))
            .ForMember(dest => dest.PhoneNumber, opts => opts.MapFrom(src => src.PhoneNumber))
            .ForAllMembers(opts => opts.Condition((src, dest, srcMember) => srcMember != null))
            .ForAllOtherMembers(opts => opts.Ignore());

ForAllMembers我不能使用，因为我已经使用了ForAllMembers。

如何忽略源中的空值，同时忽略所有其他成员进行映射？

因此，由于ForAllMembers并且ForAllOtherMembers返回void，我建议使用opts.Condition()方法，尽管这种解决方案不是很优雅

CreateMap<UpdateProfileViewModel, UserSettingModel>()
            .ForMember(dest => dest.FirstName, opts => { opts.Condition(p => p.FirstName != null); opts.MapFrom(p => p.FirstName); })
            .ForMember(dest => dest.LastName, opts => { opts.Condition(p => p.LastName != null); opts.MapFrom(p => p.LastName); })
            .ForMember(dest => dest.PhoneNumber, opts => { opts.Condition(p => p.PhoneNumber != null); opts.MapFrom(p => p.PhoneNumber); })
            .ForAllOtherMembers(opts => opts.Ignore());

Automapper链接forallmembers和forallothermembers
