error CS0103: 当前上下文中不存在名称“Profile”

但是在web.config文件已经定义了profile

<configuration>
  <connectionStrings>
    <add name="MyPetShopConnectionString" connectionString="Data Source=(localdb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\MyPetShop.mdf;Initial Catalog=MyPetShop;Integrated Security=True"
      providerName="System.Data.SqlClient" />

你试试这个呢:

List<String> lists = (List<String>)HttpContext.Current.Profile.GetProfileGroup("Cart").GetPropertyValue("ProName");
