TransactionCompletedEventHandler Delegate
.NET Framework 2.0
Note: This delegate is new in the .NET Framework version 2.0.
Represents the method that handles the TransactionCompleted event of a Transaction class.
Namespace: System.Transactions
Assembly: System.Transactions (in system.transactions.dll)
Assembly: System.Transactions (in system.transactions.dll)
'Declaration Public Delegate Sub TransactionCompletedEventHandler ( _ sender As Object, _ e As TransactionEventArgs _ ) 'Usage Dim instance As New TransactionCompletedEventHandler(AddressOf HandlerMethod)
/** @delegate */ public delegate void TransactionCompletedEventHandler ( Object sender, TransactionEventArgs e )
JScript supports the use of delegates, but not the declaration of new ones.
Parameters
- sender
The source of the event.
- e
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 Public 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
