TransactionCompletedEventHandler Delegate

Represents the method that handles the TransactionCompleted event of a Transaction class.

Namespace:  System.Transactions
Assembly:  System.Transactions (in System.Transactions.dll)

'Declaration
Public Delegate Sub TransactionCompletedEventHandler ( _
	sender As Object, _
	e As TransactionEventArgs _
)

Parameters

sender
Type: System.Object
The source of the event.
e
Type: System.Transactions.TransactionEventArgs
The TransactionEventArgs that contains the event data.

The following example shows how an application can obtain the outcome of a transaction by subscribing to the TransactionCompleted event.


        Public Shared Sub Main()
            Try
                Using scope As TransactionScope = New TransactionScope()

                    'Register for the transaction completed event for the current transaction
                    AddHandler Transaction.Current.TransactionCompleted, AddressOf Current_TransactionCompleted

                    'Perform transactional work here.

                    'Call complete on the TransactionScope based on console input
                    Dim c As ConsoleKeyInfo
                    While (True)

                        Console.Write("Complete the transaction scope? [Y|N] ")
                        c = Console.ReadKey()
                        Console.WriteLine()
                        If (c.KeyChar = "Y") Or (c.KeyChar = "y") Then
                            scope.Complete()
                            Exit While
                        ElseIf ((c.KeyChar = "N") Or (c.KeyChar = "n")) Then
                            Exit While
                        End If

                    End While

                End Using
            Catch ex As TransactionException
                Console.WriteLine(ex)
            Catch
                Console.WriteLine("Cannot complete transaction")
                Throw
            End Try
        End Sub

        'Transaction completed event handler
        Private Shared Sub Current_TransactionCompleted(ByVal sender As Object, ByVal e As TransactionEventArgs)
            Console.WriteLine("A transaction has completed:")
            Console.WriteLine("ID:             {0}", e.Transaction.TransactionInformation.LocalIdentifier)
            Console.WriteLine("Distributed ID: {0}", e.Transaction.TransactionInformation.DistributedIdentifier)
            Console.WriteLine("Status:         {0}", e.Transaction.TransactionInformation.Status)
            Console.WriteLine("IsolationLevel: {0}", e.Transaction.IsolationLevel)
        End Sub
