How to create an object of a BusinessAccessLayer_Class in Default.aspx.cs with different namespace

I am creating a ASP.Net web Application using 3-tire architecture.

First i have add a new webform and it contains some codes (name space, class etc...)

Here is the below code...

Default.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;


namespace My_Menu
{
    public partial class Default : System.Web.UI.Page
    {
           //Something like this
        BusinessAccessLayer_Class Bal = new BusinessAccessLayer_Class();       
           //******

        protected void Page_Load(object sender, EventArgs e)
        {
          
        }

        protected void btnLogin_Click(object sender, EventArgs e)
        {
           
        }



    }
}

Next i create a new folder and put a name "App_Code".
In that folder again i create a folder named "BAL".

And in that BAL folder i have added a new class named "BussinessAcessLayer.cs".

And it also contains some codes....

Here is the below code..

BusinessAccessLayer_Class.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace My_Menu.App_Code.BAL
{
    public class BusinessAccessLayer_Class
    {
    }
}

When i create a object of BusinessAccessLayer_Class in Default webform..but i failed to create it.... can anyone please help me to create a object of the BusinessAccessLayer_Class , so only i can inherit the functions from the BusinessAccessLayer_Class .......


Thanks in advance..........
