Does Value Injecter map collection properties?

Question

I'm trying to map a collection of EntityFramework objects with a collection of view models.

 public class Channel
{
    public Guid Id { get; set; }

    public string Name { get; set; }

    public IEnumerable<Report> Reports { get; set; }
}

public class ChannelListViewModel
{
    public Guid Id { get; set; }

    public string Name { get; set; }

    public IEnumerable<Report> Reports { get; set; }
}

Using the code below the Reports list is not being mapped. What am I doing wrong?

 IList<ChannelListViewModel> viewModelList = channelList.Select(x => new ChannelListViewModel().InjectFrom(x)).Cast<ChannelListViewModel>().ToList();

actually this should work, the value of Reports property should be copied on the other side, because they are of the same name `Reports` and type `IEnumerable`; probably you havent showed the actual viewmodel — Omu, Mar 15 '12 at 17:50

No, not by default, you have to use a custom injecter. This is why I switched back to automapper after trying out valueinjecter. How to map lists with ValueInjector

Thanks for the response. So it doesn't handle collections and the method you linked seems to work but what about properties that are collections? – NullReference Mar 14 '12 at 22:22
a collection is also a property, and if there is going to be a property with the same name and type at other side then the value is going to be copied – Omu Mar 15 '12 at 17:47
oh God... I almost loved VI until found it doesn't support such mega-important feature. It's much easier to write `InjectFrom` extension for AutoMapper than write `CollectionsConvention` for `Injecter`. – Sergey Metlov Feb 27 '13 at 19:35

there's an automapper simulation which does that:

http://valueinjecter.codeplex.com/releases/view/60311#DownloadId=318259

you can download it and see how collections are mapped automatically

here's the article: http://valueinjecter.codeplex.com/wikipage?title=Automapper%20Simulation&referringTitle=Home

you can see the unit tests there

The AutoMapper simulation doesn't seem to work quite right. It maps collection data incorrectly on objects that have more than one collection. – Mun Oct 22 '13 at 21:58
