Esempio

Nell'esempio di codice riportato di seguito viene illustrato come utilizzare i OnAbortTransaction OnCommitTransaction metodi e.The following code example demonstrates how to use the OnAbortTransaction and OnCommitTransaction methods. Poiché TemplateControl è una classe astratta, in questo esempio di codice viene utilizzata la Page classe, derivata dalla TemplateControl classe.Because TemplateControl is an abstract class, this code example uses the Page class, which is derived from the TemplateControl class. Account è una classe che supporta un' Debit operazione, che è transazionale e deve essere eseguita come unità.Account is a class that supports a Debit operation, which is transactional and must execute as a unit. Se durante questa operazione viene generata un'eccezione, la transazione viene terminata.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");
}
