Примеры

В следующем примере кода показано, как использовать OnAbortTransaction методы и. OnCommitTransactionThe following code example demonstrates how to use the OnAbortTransaction and OnCommitTransaction methods. Поскольку TemplateControl является абстрактным классом, в Page этом примере кода используется класс, производный от TemplateControl класса.Because TemplateControl is an abstract class, this code example uses the Page class, which is derived from the TemplateControl class. Account— Это класс, поддерживающий Debit операцию, которая является транзакционной и должна выполняться как единое целое.Account is a class that supports a Debit operation, which is transactional and must execute as a unit. Если во время этой операции возникает какое-либо исключение, транзакция завершается.If any exception is raised during this operation, the transaction is ended.

      AbortTransaction += new System.EventHandler(Sub_AbortTransaction);

   {
      Account myAccount = new Account();
      int someAmount = 500;
