How to use AutoMapper .ForMember?

Question

I am trying to set up AutoMapper to convert from Entity to DTO. I know I\'m supposed to be using .ForMember() after Mapper.CreateMap()<

Answer 1

This use as well as:

  CreateMap()
            .ForMember(d => d.CreatorUserName, m => m.MapFrom(s => 
 s.CreatedBy.UserName))
            .ForMember(d => d.LastModifierUserName, m => m.MapFrom(s => 
s.ModifiedBy.UserName)).IgnoreAllNonExisting();
