At the end of the year, it is a pity because of various reasons. However, in order to give everyone a compensation, the following dedication to the use of LOR's C # code, see what LOR is with other O / R mapping products.

IF (Book.Price. Regalid (Book.Price.Value * 0.80)) {
Book.price.value = BOOK.PRICE.VALUE * 0.80;
}
}
// The entire list is used as a transaction.
SaveResult result = books.save ();

The above is an example written by a C # source code obtained with Lor, which shows a part of the LOR unique under the .NET platform. The displayed method shown here is only decided in the current design phase, and it is very likely to change in the later period, so stay tuned! ^ _ ^
