asp.net 类库中获取session c#类中获取session

asp.net  类库中获取session c#类中获取session

1. 先引入命名空间

using System.Web;
using System.Web.SessionState;

在使用HttpContext.Current.Session获取session

HttpContext.Current.Session

2. Common.cs文件

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data;
using System.Web.SessionState;
namespace government_web.common
{
    /// <summary>
    /// 常用类
    /// </summary>
    public class Common
    {
        //是否有权限
        public bool have_permission(string name) {
            bool op = true ;
            DataTable table = (DataTable)HttpContext.Current.Session["permission"];
            if (table.Rows.Count > )
            {
            }
            else {
                //没有权限
                op = false;
            }
            return op;
        }
    }
}
