Question

I’m trying to populate this IEnumerable with values from a db.

I can’t see what I’m doing wrong.

IEnumerable<Categories> categories = new List<Categories>();

List<SelectListItem> catItems = new List<SelectListItem>();

foreach (var cats in categories)
{
    catItems.Add(new SelectListItem
                     {
                         Text = cats.CategoryName,
                         Value = cats.CategoryID.ToString()
                     });
}

Here is the class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel.DataAnnotations;
using System.Web.Mvc;

namespace SportsStore.Domain.Entities
{
    public class Categories
    {
        [Key]
        public int CategoryID { get; set; }
        public string CategoryName { get; set; }
    }

}

You only ever initialize a new collection of categories, there are never any added to the collection.
