Similar to the question posted here, I would like to map multiple sources to one destination object. In my case there is possibility of few source object could be null, in that case i want automapper to map rest of the properties from other sources.
public class People {
public string FirstName {get;set;}
public string LastName {get;set;}
}
public class Phone {
public string HomeNumber {get;set;}
public string Mobile {get;set;}
}
public class PeoplePhoneDto {
public string FirstName {get;set;}
public string LastName {get;set;}
public string HomeNumber {get;set;}
public string Mobile {get;set;}
}
var people = repository.GetPeople(1);
var phone = repository.GetPhone(4); // assume this returns null object
Mapper Config:
Mapper.CreateMap<People, PeoplePhoneDto>()
.ForMember(d => d.FirstName, a => a.MapFrom(s => s.FirstName))
.ForMember(d => d.LastName, a => a.MapFrom(s => s.LastName));
Mapper.CreateMap<Phone, PeoplePhoneDto>()
.ForMember(d => d.HomeNumber, a => a.MapFrom(s => s.HomeNumber))
.ForMember(d => d.Mobile, a => a.MapFrom(s => s.Mobile));
Extension Method:
public static TDestination Map<TSource, TDestination>(this TDestination destination, TSource source)
{
return Mapper.Map(source, destination);
}
Usage:
var response = Mapper.Map<PeoplePhoneDto>(people)
.Map(phone);
Now if the phone is null, response is also coming out as null. Is there any way response should contain at least values from People?
Not sure but can we do something in the extension method:
public static TDestination Map<TSource, TDestination>(this TDestination destination, TSource source)
{
if(source == null) //Do something;
return Mapper.Map(source, destination);
}
