Transactions

The PersistenceManager class has three static methods to manage transactions.

You can start a new transaction with

PersistenceManager.StartTransaction(IsolationLevel.ReadCommitted);

As a parameter define the IsolationLevel of the transaction. This enumeration is part of the System.Data namespace.

You can commit a running transaction with

PersistenceManager.CommitTransaction();

You can abort a running transaction with

PersistenceManager.RollbackTransaction();

So if you want to create two new Employees in a transaction, you can use

PersistenceManager.StartTransaction(IsolationLevel.ReadCommitted);

Employee e1 = new Employee("Duck", "Donald");

e1.Persist();

Employee e2 = new Employee("Duck", "Daisy");

e2.Persist();

PersistenceManager.CommitTransaction();
