AutoMapper and convert a datetime to string

Question

I can\'t get my head round the following issue. I have a feeling it is a limitation of LINQ and expression trees, but not sure how to accept the lambda body. Can I achieve this

Answer 1

If Nullable is destination then:

Mapper.CreateMap() .ForMember( dest => dest.StartDate, opt => opt.MapFrom( src => string.IsNullOrEmpty(src.StartDate) ? new DateTime?() : DateTime.ParseExact(src.StartDate, DATEFORMAT, CultureInfo.InvariantCulture) ) )
