1class SampleEnlistment2 : IEnlistmentNotification
2{
3 void IEnlistmentNotification.Commit(Enlistment enlistment)
4 {
5 enlistment.Done();
6 }
7 //其它略
8}

10class AssignTransactionDemo
11{
12 public int i;
13
14 public void AssignIntVarValue(int newValue)
15 {
16 SampleEnlistment2 myEnlistment2 = new SampleEnlistment2(this, newValue);
17 Guid guid = new Guid("{3456789A-7654-2345-ABCD-098765434567}");
18 Transaction.Current.EnlistDurable(guid, myEnlistment2, EnlistmentOptions.None);
19 i = newValue;
20 Console.WriteLine("提交前改变！i的值为：" + i.ToString());
21 }
22}

1using (TransactionScope scope1 = new TransactionScope())
2{
3 atd.AssignIntVarValue(1);
4 Console.WriteLine("事务失败！");
5 //scope1.Complete();
6 Console.WriteLine("退出区域之前，i的值为：" + atd.i.ToString());

7 Console.WriteLine("退出区域之前，i的值为：" + atd.i.ToString());
8}

1void IEnlistmentNotification.Rollback(Enlistment enlistment)
2{
3 while (_var.i != _newValue)
4 {
5 Thread.Sleep(500);
6 }
7 _var.i = _oldValue;
