.NET Framework 3.0
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)
public delegate void TransactionCompletedEventHandler ( Object sender, TransactionEventArgs e )
/** @delegate */ public delegate void TransactionCompletedEventHandler ( Object sender, TransactionEventArgs e )
Not applicable.
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.
static void Main(string[] args) { try { //Create the transaction scope using (TransactionScope scope = new TransactionScope()) { //Register for the transaction completed event for the current transaction Transaction.Current.TransactionCompleted += new TransactionCompletedEventHandler(Current_TransactionCompleted); //Call complete on the TransactionScope based on console input ConsoleKeyInfo c; while (true) { Console.Write("Complete the transaction scope? [Y|N] "); c = Console.ReadKey(); Console.WriteLine(); if ((c.KeyChar == 'Y') || (c.KeyChar == 'y')) { scope.Complete(); break; } else if ((c.KeyChar == 'N') || (c.KeyChar == 'n')) { break; } } } } catch (System.Transactions.TransactionException ex) { Console.WriteLine(ex); } catch { Console.WriteLine("Cannot complete transaction"); throw; } } //Transaction completed event handler static void Current_TransactionCompleted(object sender, TransactionEventArgs e) { 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); }
