Automapper mapping properties on a condition

Question

Hi there,
I appreciate if anyone could assist me please?
I am using AutoMapper but i am finding it difficult to map the contents depending on a condition.
e.g
I have a parameter called includeOptional which can be either null or 1 .
If it is null I do not want to map the additional properties to the destination. The properties in the destination are nullable.
if the value is 1 I would like to map the additional elements.
Currently i am mapping everything from the source to destination as i am finding it difficult to map.
I will share some of my code:
IEnumerable<CustomersDAO> customers = databaseProvider.GetCustomersById(CustId);
//additional processing..
var result = null;
if(includeOptional == null)
result = Mapper.Map<List<CustomerDAO>, Customer[]>(customers);
else
result = Mapper.Map<List<CustomerDAO>, Customer[]>(customers);
How would i go about mapping the properties from source to destination for each of the customers in the collection if the condition is met.
I have the following but i cannot seem to get it work.
configuration.CreateMap<CustomerDAO, Customer>()
ForMember(dto => dto.StartDate, opt => opt.MapFrom(src => src.StartDate))
.ForMember(dto => dto.Name, opt => opt.MapFrom(src => src.Name))
.ForMember(dto => dto.Category, opt => opt.MapFrom(src => src.Category));

Hello IndusKing,
From your description, it seems that your issue is related the usage of the Automapper, for this, I suggest that you could post Automapper related issues to the Automapper specific forum:
