I have a foreach loop and need to execute some logic when the last item is chosen from the List, e.g.:

You can make an extension method specially dedicated to this:

public static class EnumerableExtensions {
    public static bool IsLast(this List items, T item)
        {
            if (items.Count == 0)
                return false;
            T last = items[items.Count - 1];
            return item.Equals(last);
        }
    }

and you can use it like this:

foreach (Item result in Model.Results)
{
    if(Model.Results.IsLast(result))
    {
        //do something in the code
    }
}
