The following code example demonstrates how to use ContextUtil to create a transactional ServicedComponent.
[Transaction] public class TransactionalComponent : ServicedComponent { public void TransactionalMethod (string data) { ContextUtil.DeactivateOnReturn = true; ContextUtil.MyTransactionVote = TransactionVote.Abort; // Do work with data. Return if any errors occur. // Vote to commit. If any errors occur, this code will not execute. ContextUtil.MyTransactionVote = TransactionVote.Commit; } }
