求助高手：关于用sqlhelper实现稍复杂点的事务判断
小弟最近想用sqlhelper来替换一下原来的socut控件，其实主要是想用sqlhelper中的事务功能。现在有一个aspx.cs页面的判断逻辑比较多，我按如下处理了一下总是审核失败（原来没有tran事务的try...catch等代码时是可以正常审核成功的），不知道应该如何用sqlhelper来实现这种事务控制，还请各位指点指点，谢谢了。//审批子程序

} --------------------编程问答-------------------- 我们做事务，都是事务类有一个SQL字符串列表，是静态的，在各个地方添加SQL语句，最后执行时做事务处理，失败后悔滚 --------------------编程问答-------------------- using(TransactionScope scope = new TransactionScope())
{
//方法一
scope.Commit();
}
