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;

        }

    }

}
