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.
PgSqlConnection connection = new PgSqlConnection(
"host=server;database=test;user id=postgres;");
connection.TransactionStateChanged += new TransactionStateChangedEventHandler(connection_TransactionStateChanged);
connection.TransactionStateChanging += new TransactionStateChangingEventHandler(connection_TransactionStateChanging);
connection.Open();
// ...
PgSqlTransaction 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...
}
}
Dim connection As New PgSqlConnection( _
"host=server;database=test;user id=postgres;")
AddHandler connection.TransactionStateChanged, New TransactionStateChangedEventHandler(AddressOf &_ Me.connection_TransactionStateChanged)
AddHandler connection.TransactionStateChanging, New TransactionStateChangingEventHandler(AddressOf &_ Me.connection_TransactionStateChanging)
connection.Open()
'...
Dim Transaction As PgSqlTransaction
Transaction = connection.BeginTransaction()
'...
Transaction.Commit()
'...
Private Sub connection_TransactionStateChanged(ByVal sender As Object, ByVal e As TransactionStateChangedEventArgs)
If (e.Action = TransactionAction.Commit) Then
'...
End If
End Sub
Private Sub connection_TransactionStateChanging(ByVal sender As Object, ByVal e As TransactionStateChangingEventArgs)
If (e.Action = TransactionAction.Commit) Then
'...
End If
End Sub
