AutoMapper mapping model list - asp.net-mvc-3

Question

I am trying to use AutoMapper for the first time and have some problems with it.
My code is below and I get error below. Maybe someone could show how to map the list of models?
cannot convert from 'System.Linq.IQueryable<AnonymousType#1>' to 'Entity.Product' C:\Users\Administrator\Projects\PC\trunk\PC\Controllers\AdminController.cs 37 100 PC
public class ProductViewModel
{
public int Id { get; set; }
public string Name { get; set; }
public int UsersCount { get; set; }
}
var products = _repository.GetProducts(true).Select(p=> new
{
p.Id,
p.Name,
UsersCount = 0
});
Mapper.CreateMap<Product, ProductViewModel>();
ViewData["Products"] = Mapper.Map<IEnumerable<Product>, IEnumerable<ProductViewModel>>(products); //Error appears on products object
//Product domain model(linq2sql generated model)
public partial class Product : INotifyPropertyChanging, INotifyPropertyChanged
{
private static PropertyChangingEventArgs emptyChangingEventArgs = new PropertyChangingEventArgs(String.Empty);
private int _Id;
private bool _Active;
private System.Nullable<int> _Sort;
private System.Nullable<int> _Category;
private string _Name;
private int _ProductTypeId;
private decimal _Price;
private System.Nullable<int> _Months;
private System.Nullable<int> _Credits;
private string _Features;
private string _BlockReason;
private string _BuyUrl1;
private string _BuyUrl2;
private bool _UsersManager;
}

Answer 1

In your LINQ query you select an anonymous object. Make sure you select a Product which is your source type (or more specifically IEnumerable<Product>):
IEnumerable<Product> products = _repository.GetProducts(true);
IEnumerable<ProductViewModel> productsViewModel = Mapper.Map<IEnumerable<Product>, IEnumerable<ProductViewModel>>(products);
return View(productsViewModel);
Also do not call Mapper.CreateMap<TSource, TDest> inside your controller action. This must be called only once in the lifetime of the AppDomain, ideally in your Application_Start.
Also notice that I have gotten rid of ViewData which is a great thing. You don't need ViewData. You are working with view models. That's what they are supposed to do. Contain information that will be needed by your view in a strongly typed manner.
