Примеры

В следующем примере кода показано, как зарегистрировать пользовательский обработчик событий для события CommitTransaction.The following code example demonstrates how to register a custom event handler for the CommitTransaction event. Поскольку TemplateControl является абстрактным классом, в этом примере кода используется класс Page, который является производным от класса TemplateControl.Because TemplateControl is an abstract class, this code example uses the Page class, which is derived from the TemplateControl class. Account — это класс, поддерживающий операцию Debit, 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.


  private void Page_Load(object sender, System.EventArgs e)
  {
      AbortTransaction += new System.EventHandler(Sub_AbortTransaction);
   CommitTransaction += new System.EventHandler(Sub_CommitTransaction);
      try
   {
      Account myAccount = new Account();
      int someAmount = 500;
      myAccount.Debit(someAmount); 
      ContextUtil.SetComplete(); 
   }
   catch(Exception)
   {
      ContextUtil.SetAbort();
   }
  }

private void Sub_AbortTransaction(object sender,System.EventArgs e)
{
   // Code for RollBack activity goes here.
   Response.Write("Transaction Aborted");
}
private void Sub_CommitTransaction(object sender,System.EventArgs e)
{
   // Code for Commit Activity goes here.
   Response.Write("Transaction Commited");
}
