一个队asp.net session进行了再次封装的C#类的代码

using System.Web;

namespace DotNet.Utilities
{
    public static class SessionHelper2
    {
        public static void Add(string strSessionName, string strValue)
        {
            HttpContext.Current.Session[strSessionName] = strValue;
            HttpContext.Current.Session.Timeout = 20;
        }

        public static void Adds(string strSessionName, string[] strValues)
        {
            HttpContext.Current.Session[strSessionName] = strValues;
            HttpContext.Current.Session.Timeout = 20;
        }

        public static void Add(string strSessionName, string strValue, int iExpires)
        {
            HttpContext.Current.Session[strSessionName] = strValue;
            HttpContext.Current.Session.Timeout = iExpires;
        }

        }

        public static string Get(string strSessionName)
        {
            if (HttpContext.Current.Session[strSessionName] == null)
            {

            }
            else

            }
        }

    }
}
