1，首先建立购物车模型类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace Ants.WebPart.Models
{
public class ShopCarModel
{
      public int Id { get; set; }
      public string Title { get; set; }
      public string Other { get; set; }
}
}

2.实现购物车功能的两个方法：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Ants.WebPart.Models;
using Ants.Common;

namespace Ants.WebPart
{
public class ShopCarTask
{
      private static string _cookieName =TextUtils.ConvertToBasic64("MyshopcarPowerByAnts");
      Ants.Provider.ISerializerProvider serializer = new Ants.Provider.JsonSerializerProvider();
      public void SetShopCar(IList<ShopCarModel> goods)
      {
         CookieUtils.Write(_cookieName,TextUtils.ConvertToBasic64(serializer.ToString(goods)));
      }
      public void SetShopCar(IList<ShopCarModel> goods, int expires)
      {
         CookieUtils.Write(_cookieName, TextUtils.ConvertToBasic64(serializer.ToString(goods)),expires);
      }
      public IList<ShopCarModel> GetShopCar()
      {
         return serializer.parse < IList < ShopCarModel >>(CookieUtils.Read(_cookieName));
      }
}
}
