C＃ - System.Transactions.TransactionScope [英] C# - System.Transactions.TransactionScope

问题描述

我很好奇TransactionScope类

I was curious about the TransactionScope class.

在大多数情况下，我认为它的目的是为数据库连接（这是我用它）。

For the most part, I assume it was intended for database connections (which is what I've used it for).

我的问题，是你能放的任意的code在一个TransactionScope的使用块该操作是事务？ MS文档并没有明确这一点。

My question, is can you put any code in the using-block of a TransactionScope to make it transactional? MS documentation is not clear on this.

如果它可以被用来制造code比数据库连接事务性的其他，这是支持的呢？这似乎疯了我，如果它可以使有System.IO.File运营事务。

If it can be used to make code other than database connections transactional, which ones are supported? It would seem crazy to me if it could make System.IO.File operations transactional.

推荐答案

的TransactionScope不仅对数据库。实现IEnlistmentNotification接口，可参与两阶段每个组件提交的事务范围。

TransactionScope is not only for the databases. Every component that implements IEnlistmentNotification interface can participate in two-phase commit of the transaction scope.

下面是事务性内存中的一个例子： <一href="http://www.$c$cproject.com/KB/dotnet/Transactional_Repository.aspx">http://www.$c$cproject.com/KB/dotnet/Transactional_Repository.aspx

Here is an example of transactional in-memory storage: http://www.codeproject.com/KB/dotnet/Transactional_Repository.aspx

另外，我不知道是否有.NET中的事务性文件IO组件，但它是pretty的容易实现这样的部件 - 最新的操作系统Vista一样和Windows Server 2008有交易文件IO支持。

Also, I'm not sure if there are components in .NET for transactional file IO, but it is pretty easy to implement such component - latest OS like Vista and Windows Server 2008 have support for transaction file IO.
