How to ignore null values for all source members during mapping in Automapper 6?

Method Condition now has five overloads, one of which accepts predicate of type

Func<TSource, TDestination, TMember, bool>

this TMember parameter is the source member. So you can check source member for null:

CreateMap<StatusLevelDTO, StatusLevel>()
     .ForAllMembers(opts => opts.Condition((src, dest, srcMember) => srcMember != null));

This might be late, but for those who are still looking, this might solve your problem the same as mine.

I agree with @sergey to use:

CreateMap<StatusLevelDTO, StatusLevel>()
    .ForAllMembers(opts => opts.Condition((src, dest, srcMember) => srcMember != null));

But mapping nullable to non nullable will be an issue like int? to int it will always return 0. to fix it you can convert int? to int in mapping.

CreateMap<int?, int>().ConvertUsing((src, dest) => src ?? dest);
CreateMap<StatusLevelDTO, StatusLevel>()
     .ForAllMembers(opts => opts.Condition((src, dest, srcMember) => srcMember != null));
