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

C#

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

C#

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..........

In Visual Studio, Right click on class file and go to properties.

Check for BuildAction property of file. This should be set to "Compile"

then you can create instance as below

WebApplication1.App_Code.BAL.BusinessAccessLayer_Class d = new WebApplication1.App_Code.BAL.BusinessAccessLayer_Class();

if you set using directive like below you can create instance without full class name.

C#

using WebApplication1.App_Code.BAL;

namespace WebApplication1
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            BusinessAccessLayer_Class d = new BusinessAccessLayer_Class();
