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.
UniConnection connection = new UniConnection(
"Provider=SQL Server;Data Source=SERVER;Initial Catalog=Northwind;User ID=sa;");
connection.TransactionStateChanged += new TransactionStateChangedEventHandler(connection_TransactionStateChanged);
connection.TransactionStateChanging += new TransactionStateChangingEventHandler(connection_TransactionStateChanging);
connection.Open();
// ...
UniTransaction 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 UniConnection( _
"Provider=SQL Server;Data Source=SERVER;Initial Catalog=Northwind;User ID=sa;")
AddHandler connection.TransactionStateChanged, New TransactionStateChangedEventHandler(AddressOf &_ Me.connection_TransactionStateChanged)
AddHandler connection.TransactionStateChanging, New TransactionStateChangingEventHandler(AddressOf &_ Me.connection_TransactionStateChanging)
connection.Open()
'...
Dim Transaction As UniTransaction
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
