我目前正在使用IDbTransaction，而我似乎无法使用它我收到了无效的引用错误，我确定我错了，所以我该如何处理使用IDbTransaction？

所以WebMethod通过JS上的函数提供信息，然后将它发送到BL，在那里我试图在方法之外声明连接字符串，所以我可以打开连接一次，然后再做所有的方法，但这没有用。我需要做的是创建一个条目（Master），它可以有很多DO，而那些DO可以有很多DODetails。我需要先创建主数据库，因此可以使用主ID创建DO，并使用DO ID创建DODetail。所以它在DB中有3个程序，所以如果其中任何一个失败，我想要回滚，我怎么能这样做？
任何帮助都会受到很大的影响。
