Maintain your Session variable in Class file using C#

on
Hello and Welcome,

Here I am going to discuss with you regarding Session variable in one class file to maintain it. You do not need to check it on each and every pages. Here we goes.

First we will create on class file to create and maintain Session variable. Create Class name like "Session_Class".
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

///
/// Summary description for clsSession
///

public class Session_Class
{
    public Session_Class()
    {
        //
        // TODO: Add constructor logic here
        //
    }

    public bool CheckSession()
    {
        if (HttpContext.Current.Session["uid"] == null)
        {
            return false;
        }
        else
        {
            return true;
        }
    }

    public void CheckSession(out string strUserName, out string strUserID)
    {
        strUserName = "";
        strUserID = "";
        if (HttpContext.Current.Session["userName"] != null && HttpContext.Current.Session["uid"] != null)
        {
            strUserName = Convert.ToString(HttpContext.Current.Session["userName"]);
            strUserID = Convert.ToString(HttpContext.Current.Session["uid"]);
        }
    }

    public void CreateSession(string strId, string strUserName)
    {
        HttpContext.Current.Session.Add("uid", strId);
        HttpContext.Current.Session.Add("userName",strUserName);
    }

    public void RemoveSession(string strId, string strUserName)
    {
        HttpContext.Current.Session.Remove("uid");
        HttpContext.Current.Session.Remove("userName");
        HttpContext.Current.Session.RemoveAll();
    }
}


Here is .aspx page

<div><asp:LinkButton ID="lnkLogin" runat="server" OnClick="Login">Login</asp:LinkButton> <asp:LinkButton ID="lnkLogOut" runat="server" OnClick="Logout">Logout</asp:LinkButton>
 <asp:LinkButton ID="lnkCheckSessionNow" runat="server" OnClick="CheckNow">Check Session Now</asp:LinkButton>
</div>


.aspx.cs page

protected void Login(object sender, EventArgs e)
    {
        Session_Class objSession = new Session_Class();
        objSession.CreateSession("ved","vedPathak");
        if (objSession.CheckSession() == true)
        {
            string strUserName = "";
            string strUserId = "";
            objSession.CheckSession(out strUserName, out strUserId);

            Response.Write("Hello" + strUserName + " " + strUserId);
        }
    }

    protected void Logout(object sender, EventArgs e)
    {
       Session_Class objSession = new Session_Class();
        objSession.RemoveSession("uid", "userName");
    }

    protected void CheckNow(object sender, EventArgs e)
    {
       Session_Class objSession = new Session_Class();
        if (objSession.CheckSession() == true)
        {
            Response.Write("Session is still alive now.");
        }
        else
        {
            Response.Write("Session is Expired now.");
        }
    }
