                    SqlDataReader reader = command.ExecuteReader();
                    while (reader.Read()) // --> here it skips while loop ????
                    {

                        string ImagePath = (string)reader["DbImagePath"];

                    }

                }

            }
        }
        return RedirectToAction("Index", "Admin");
    }

while (reader.Read()) { } will break when there are no more records to read. Since your first command deletes the record identified by id, there will never be anything to read with that id.
