特别说明请注意：
根许多网友反应，
using Maticsoft.Functions;
这些代码看不懂
其实Functions 这个dll是我定义常用的函数类，如果需要跟我联系索取http://sql8.net 下面有我的群号，
其中
ArtsShop.Model.Arts_Product _p = new ArtsShop.Model.Arts_Product();
ArtsShop.BLL.Arts_Product p = new ArtsShop.BLL.Arts_Product();
_p = p.GetModel(id);
这是我的商品信息的类，三层结构，这个在用时你们只能换成你们自己的，这些代码完全可以删除，
比如 MyDr[1] = _p.Title;
用来读取商品名的，你们可以改MyDr[1] = dr["productname"].ToString();就行了，
