How to assign and access Session Variables from a Class in Asp.Net?

What is a Session Variable and why use it?

Every time a user visits a website, a new session is maintained for a specific period of time. During this session, the server records specific information about the user till the user logs out or closes the browser. The recorded sessions can be used throughout the website (pages) for specific reasons. This information can be stored using “Session Variables”.

E.g. Session(“mark”) = “a value”

The above example can be written in a variety of ways in a web page.

Design Mode (Asp.Net)

<% If Session("mark ") = “x” Then
    Some code here…
Else
    And here…
End If %>
                

Code behind

Protected Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles frmMemberList.Load 
    If Session("mark ") = “x” Then
        Some code here…
    Else
        And here…
    End If
End Sub
