c#在类中使用session

先要继承页面的System.Web.UI.Page

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI.WebControls;
using DevExpress.Web;
using DevExpress.Web.Internal;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Data;
using System.Data.Common;
using System.Web.Script.Serialization;

namespace MALL_simple.Qhot
{
    public class Basics : System.Web.UI.Page
    {
｝
｝

使用的时候用

HttpContext.Current.Session["FrameMallAddress"]

获取就行了
