Automapper copy List to List

Kris-I picture Kris-I · Jan 17, 2012 · Viewed 71.5k times · Source

I have these classes:

public class Person {
    public int Id{ get; set ;}
    public string FirstName{ get; set ;}
    public string LastName{ get; set ;}
}

public class PersonView {
    public int Id{ get; set ;}
    public string FirstName{ get; set ;}
    public string LastName{ get; set ;}
}

I defined this:

Mapper.CreateMap<Person, PersonView>();
Mapper.CreateMap<PersonView, Person>()
    .ForMember(person => person.Id, opt => opt.Ignore());

That's work for this:

PersonView personView = Mapper.Map<Person, PersonView>(new Person());

I'd like to make the same but for List<Person> to List<PersonView> but I don't find the right syntax.

Thanks

Once you've created the map (which you've already done, you don't need to repeat for Lists), it's as easy as:

List<PersonView> personViews = 
    Mapper.Map<List<Person>, List<PersonView>>(people);

You can read more in the AutoMapper documentation for Lists and Arrays.
