Question

Answer 1

The best way to retrieve an item by index is to reference your enumerable collection with an array using Linq in this way:

using System.Linq;
...
class Model {
    IEnumerable Products;
}
...
// Somewhere else in your solution,
// assume model is an instance of the Model class
// and that Products references a concrete generic collection
// of Product such as, for example, a List.
...
var item = model.Products.ToArray()[index];
