Se visit the MSDN page per TransactionScope
, si dovrebbe trovare questo esempio ben documentato:
try
{
// Create the TransactionScope to execute the commands, guaranteeing
// that both commands can commit or roll back as a single unit of work.
using (TransactionScope scope = new TransactionScope())
{
using (SqlConnection connection1 = new SqlConnection(connectString1))
{
// Opening the connection automatically enlists it in the
// TransactionScope as a lightweight transaction.
connection1.Open();
// Create the SqlCommand object and execute the first command.
SqlCommand command1 = new SqlCommand(commandText1, connection1);
returnValue = command1.ExecuteNonQuery();
writer.WriteLine("Rows to be affected by command1: {0}", returnValue);
// If you get here, this means that command1 succeeded. By nesting
// the using block for connection2 inside that of connection1, you
// conserve server and network resources as connection2 is opened
// only when there is a chance that the transaction can commit.
using (SqlConnection connection2 = new SqlConnection(connectString2))
{
// The transaction is escalated to a full distributed
// transaction when connection2 is opened.
connection2.Open();
// Execute the second command in the second database.
returnValue = 0;
SqlCommand command2 = new SqlCommand(commandText2, connection2);
returnValue = command2.ExecuteNonQuery();
writer.WriteLine("Rows to be affected by command2: {0}", returnValue);
}
}
// The Complete method commits the transaction. If an exception has been thrown,
// Complete is not called and the transaction is rolled back.
scope.Complete();
}
}
catch (TransactionAbortedException ex)
{
writer.WriteLine("TransactionAbortedException Message: {0}", ex.Message);
}
catch (ApplicationException ex)
{
writer.WriteLine("ApplicationException Message: {0}", ex.Message);
}
Il commento che contiene il massimo valore è questa:
il metodo completo commit della transazione. Se è stata generata un'eccezione, Complete non viene richiamato e la transazione viene annullata.
Quindi, se non vengono lanciate eccezioni, è possibile continuare. Metti il tuo reindirizzamento dopo scope.Complete()
. Se viene generata un'eccezione, la transazione ha avuto esito negativo e è stata automaticamente ripristinata. Si potrebbe doppio verificare lo stato delle transazioni (come altri hanno scritto) dopo la chiamata a Complete()
e prima di reindirizzare, tramite Transaction.Current.TransactionInformation.Status
:
if (Transaction.Current.TransactionInformation.Status == TransactionStatus.Committed)
{
// do redirect
}
