Session不能再pageload前获取吗？
Imports System.Data
Imports System.Net
Imports System.Net.Mail
Imports System.Net.Mail.MailMessage
Imports System.Net.Mail.SmtpClient
Partial Class ClassesReqN 
  '提取用户信息
  Dim struseridd As String = Session("Userid").ToString()
  
  Private sub Page_Load


提示错误
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration.
