以下代码应该在你的登录页面。

try this

The below code should be in your Loging page.

Sub validateuser()
       Try
           sqlcon = New OleDbConnection(constr)
           sqlcon.Open()
           sqlcmd = New OleDbCommand("SELECT COUNT(*) FROM att_userrole WHERE username = '" + Login1.UserName + " AND password = '" + Login1.Password + "'", sqlcon)
           retval = sqlcmd.ExecuteScalar
           If retval = 1 Then
               sqlcmd = New OleDbCommand("SELECT role, emailid FROM att_userrole WHERE username = '" + Login1.UserName + "'", sqlcon)
               sqlrdr = sqlcmd.ExecuteReader()
               sqlrdr.Read()
               Session("username") = Login1.UserName
               getrole = (sqlrdr.Item("role"))
               Session("userrole") = getrole
               getemail = (sqlrdr.Item("emailid"))
               Session("reqemailid") = getemail
               Response.Redirect("~\Home.aspx")
               'Response.Write("you are valid " & Session("username") & " with role " & getrole)
           Else
               'IF USERNAME IS INVALID
               '-----YOUR CODE GOES HERE----
              lbl_msg.Text = ("Invalid login attmept")
 
           End If
       Catch ex As Exception
           lbl_msg.Text = ex.Message.ToString
       End Try
   End Sub

经过身份验证和检查后，您可以在会话中保存详细信息。然后在其他页面中查看会话值，如下所示

After authentication and checking you save the details in Sessions. Then in other pages just check the session values like the below

If Session("username") = "" Then
          loggedin = 0
          Response.Redirect("~\login.aspx")
      Else
          Master.ChangeLabel("Welcome " & Session("username") & " | " & Session("userrole") & " | ")
      End If
      If Session("userrole") = "Admin" Then
         'You are admin and put your code here
      Else
          'You are guest, put your code here

      End If
