Bind GridView from database using ArrayList in ASP.Net

Hi! I want bind GridView from database using ArrayList. But my code not worked. Who is you can help me? I shared code below:

public System.Collections.ArrayList GetTime(int user, int kod)
        {
            SqlConnection con = new SqlConnection(UserData);
            SqlCommand cmd = con.CreateCommand();
            System.Collections.ArrayList result = new System.Collections.ArrayList();
            string sql = "select kod,dshbe,sshbe,chshbe,pshbe,jma,shbe,koduser where koduser ="+user+"and kod =" + vr;
            cmd.CommandText = sql; 
            con.Open();
            try
            {
                System.Data.SqlClient.SqlDataReader r = cmd.ExecuteReader();
                if (r != null)
                {
                    while (r.Read())
                    {
                        GetDay d = new GetDay();
                        d.kod = r.GetInt32(0);
                        d.dsh = r.GetString(1);
                        d.ssh = r.GetString(2);
                        d.chsh = r.GetString(3);
                        d.psh = r.GetString(4);
                        d.jma = r.GetString(5);
                        d.shb = r.GetString(6);
                        d.user = r.GetInt32(7);
                        result.Add(d);
                    }
                }
            }
            catch { }
            con.Close();
            return result;
        }

    [Serializable]
    public class GetDay
    {
      public int kod;
      public string dsh;
      public string ssh;
      public string chsh;
      public string psh;
      public string jma;
      public string shb;
      public int user;
    }
