Removing using from this code

/// <summary>
        /// Get Inventory Dictionary for passed category
        /// </summary>
        /// <param name="Category">Category</param>
        /// <returns></returns>
        public Dictionary<string, string> GetInventoryDictionaryByCategory(string Category)
        {
            Dictionary<string, string> list = new Dictionary<string, string>();

            ItemsTableAdapter ta = new ItemsTableAdapter();

            InventoryDS.ItemsDataTable dt = this.GetItemsByCategory(Category);
                
                    ta.Fill(dt);

                foreach (InventoryDS.ItemsRow dr in dt.Rows)
                {
                    list.Add(dr.itemdesc1, dr.pk.ToString());
                }                            

            return list;
        }        

seemed to bypass the errors, but what was wrong with my original way?
