Can Automapper map a paged list?

Question

I'd like to map a paged list of business objects to a paged list of view model objects using something like this:

var listViewModel = _mappingEngine.Map<IPagedList<RequestForQuote>, IPagedList<RequestForQuoteViewModel>>(requestForQuotes);

The paged list implementation is similar to Rob Conery's implementation here: http://blog.wekeroad.com/2007/12/10/aspnet-mvc-pagedlistt/

How can you setup Automapper to do this?

Answer 1

AutoMapper does not support this out of the box, as it doesn't know about any implementation of IPagedList<>. You do however have a couple of options:

1. Write a custom IObjectMapper, using the existing Array/EnumerableMappers as a guide. This is the way I would go personally.

2. Write a custom TypeConverter, using:

   Mapper
       .CreateMap<IPagedList<Foo>, IPagedList<Bar>>()
       .ConvertUsing<MyCustomTypeConverter>();
   

   and inside use Mapper.Map to map each element of the list.
