🔀 Conditional Mapping Explained
CreateMap<User, UserBasicDTO>()
.ForMember(dest => dest.FullName,
opt => opt.MapFrom(src => $"{src.FirstName} {src.LastName}"))
.ForMember(dest => dest.Email,
opt => opt.Condition(src => src.IsActive)); // Only map if IsActive is true
// Result:
// Active User: Email is mapped
// Inactive User: Email is NOT mapped (remains empty/null)Use Case: Hide sensitive information based on conditions, map only relevant data based on state, implement conditional business rules.
