hI wkm1925,

Check this example. Now please take its reference and correct your code.

Using EntityFramework

protected void Page_Load(object sender, EventArgs e)
{
    List<Genre> geners = getGenre.GetGenre()
        .Select(x => new Genre
        {
            GenreId = x.GenreId,
            Name = x.Name
        }).ToList();
}
public class getGenre
{
    public int GenreId { get; set; }
    public string Name { get; set; }
    public static List<getGenre> GetGenre()
    {
        List<Genre> Genre = new List<Genre>();
        using (MusicStoreDB entities = new MusicStoreDB())
        {
            string procedureName = "getGenre";
            return entities.Database.SqlQuery<getGenre>(procedureName).ToList();
        }
    }
}

Using ADo.Net

Namespaces

using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Linq;

Code

protected void Page_Load(object sender, EventArgs e)
{
    List<Genre> geners = getGenre.GetGenre()
        .Select(x => new Genre
        {
            GenreId = x.GenreId,
            Name = x.Name
        }).ToList();
}
public class getGenre
{
    public int GenreId { get; set; }
    public string Name { get; set; }

    public static List<getGenre> GetGenre()
    {
        List<getGenre> genres = new List<getGenre>();
        using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["constr"].ConnectionString))
        {
            DataTable dt = new DataTable();
            SqlCommand cmd = new SqlCommand("getGenre", conn);
            cmd.CommandType = CommandType.StoredProcedure;
            SqlDataAdapter da = new SqlDataAdapter(cmd);
            da.Fill(dt);
            foreach (DataRow dr in dt.Rows)
            {
                getGenre genre = new getGenre();
                genre.GenreId = Convert.ToInt32(dr["GenreId"]);
                genre.Name = Convert.ToString(dr["Name"]);
                genres.Add(genre);
            }
        }

        return genres;
    }
}
