SQL Server CE回滚不会撤消删除

Question

我在.NET Compact Framework 3.5中使用SQL Server CE 3.5和C#.在我的代码中,我插入一行,然后启动一个事务,然后从表中删除该行,然后对该事务进行回滚.但这并没有撤消删除.为什么不？这是我的代码:

SqlCeConnection conn = ConnectionSingleton.Instance;
conn.Open();
UsersTable table = new UsersTable();
table.DeleteAll();
MessageBox.Show("user count in beginning after delete: " + table.CountAll());
table.Insert(
new User(){Id = 0, IsManager = true, Pwd = "1234", Username = "Me"});
MessageBox.Show("user count after insert: " + table.CountAll());
SqlCeTransaction transaction = conn.BeginTransaction();
table.DeleteAll();
transaction.Rollback();
transaction.Dispose();
MessageBox.Show("user count after rollback delete all: " + table.CountAll());

消息表明一切都按预期工作,直到表的计数为0表示回滚未撤消删除.

我刚刚在微软的论坛上得到了解答.您需要使用SqlCeCommand对象的Transaction属性将SqlCeComand对象与事务相关联.
