C#数组转Dictionary字典

 private Dictionary<string, Product> m_IdToProduct;
        private Dictionary<string, Product> m_StoreSpecificIdToProduct;

  internal void AddProducts(IEnumerable<Product> products)
        {
            set.UnionWith(products);
            all = set.ToArray();
            //根据指定key存储class到Dic字典中
            m_IdToProduct = all.ToDictionary(x => x.definition.id);
            m_StoreSpecificIdToProduct = all.ToDictionary(x => x.definition.storeSpecificId);
        }
