The event handler receives an argument of type TransactionStateChangedEventArgs containing data related to this event. The following TransactionStateChangedEventArgs properties provide information specific to this event.
This sample demonstrates how to use the
TransactionStateChanged and
TransactionStateChanging events.

OracleConnection connection = new OracleConnection(
"User Id=Scott;Password=tiger;Data Source=Ora;");
connection.TransactionStateChanged += new TransactionStateChangedEventHandler(connection_TransactionStateChanged);
connection.TransactionStateChanging += new TransactionStateChangingEventHandler(connection_TransactionStateChanging);
connection.Open();
// ...
OracleTransaction tr = connection.BeginTransaction();
// ...
tr.Commit();

void connection_TransactionStateChanging(object sender, TransactionStateChangingEventArgs e) {
if (e.Action == TransactionAction.Commit) {
// do somthing...
}
}
void connection_TransactionStateChanged(object sender, TransactionStateChangedEventArgs e) {
if (e.Action == TransactionAction.Commit) {
// do somthing...
}
