[RESOLVED] Not able to retrieve and compare value from list

[mtn*rain]

Trying to do a search on a windows form on ISBN. When I do the search, it does not locate the value, although the bin folder does show the value in there.

                //IList<Book> listBooks = new List<Book>();
                Book book = new Book();
                string fISBN = FindISBNTxt.Text;
                BookMgr bookMgr = new BookMgr();
                bookMgr.FindBook(book);
                Book fdBook = bookMgr.FindBook(book);
                if (String.Equals(fISBN, fdBook))
                {
                    MessageBox.Show(book.title + " has been found!");
                }
                else
                {
                    MessageBox.Show(book.title + " is not in list!");
                }

    public class BookSvcBinImpl : IBookService
    {
        public Book RetrieveBook()
        {
            FileStream loadStream = new FileStream("Book.bin", FileMode.Open, FileAccess.Read);
            IFormatter formatter = new BinaryFormatter();
            Book bookX = formatter.Deserialize(loadStream) as Book;
            loadStream.Close();
            return bookX;
        }

    public class BookMgr : Manager
        public Book FindBookMgr() 
        {
            //Factory factory = new Factory();
            IBookService bookSvc = (IBookService)GetService(typeof(IBookService).Name);
            bookSvc.RetrieveBook();
            Book bookF = bookSvc.RetrieveBook();
            return bookF;
        }
