I am new to asp.net. when I am trying to create an object of the BookDAL class in AddBook.aspx page it doesn't work, and I get the error above, though I have added the reference and and namespace properly, any help please

enter image description here

This is my code 

namespace DataAccessLayer.DALS.OLIBDAL
{
   public  class BookDAL
   {
       public int B_Id { get; set; }
       public string IDwithChar { get; set; }
       public int Category_Id { get; set; }
       public string Title { get; set; }
       public string ISBN { get; set; }
       public DateTime Published_Date { get; set; }
       public DateTime System_Date { get; set; }
       public string Language { get; set; }
       public string Edition { get; set; }
       public string Author { get; set; }
       public bool Featured { get; set; }
       public string Description { get; set; }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using DataAccessLayer;

public partial class OLIB_AddBook : System.Web.UI.Page
{
    BookDAL book = new BookDAL(); 

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

    protected void Button1_Click(object sender, EventArgs e)

    }
}

The problem is that you're not referencing the namespace correctly. As the BookDAL is located inside DataAccessLayer.DALS.OLIBDAL but you're referencing only DataAccessLayer. So include the following namespace in OLIB_AddBook.aspx.cs page:

DataAccessLayer.DALS.OLIBDAL

Note ASP.Net assumes every folder as a namespace. When you include a parent namespace the classes inside the child namespace(s) will not be accessible until you include them in your working class.

Namespace is:

DataAccessLayer.DALS.OLIBDAL

Not:

DataAccessLayer

So replace:

using DataAccessLayer;

with:

using DataAccessLayer.DALS.OLIBDAL;
