Transactionscope异常处理 [英] Transactionscope Exception Handling

问题描述

我认为TransactionAbortedException的文档缺少什么时候可以发生.

如果您不对初始交易执行Scope.Complete，则不会发生这种情况.换句话说，无法执行Scope.Complete意味着它将使用block静默退出transactionscope. (由于没有其他方法可以静默取消transactionscope，因此可以接受，但应清楚记录在案.)
如果您需要警告您的流程您正在中止初始事务，则应通过抛出异常来这样做，该异常将自动以静默方式关闭transactionscope.您可能希望使用block来尝试/捕获包装您的transactionscope，以捕获这些异常.

但是，如果使用连接到环境事务的块对具有自己的transactionscope的进程进行了多个相同级别的调用，则在调用Scope.Complete失败时将获得异常.当后续调用启动transactionscope时，它会看到一个肮脏的事务，并会在该点发出transactionabortedexception.
但是，如果您嵌套调用，并且子调用未发出scope.complete，则在它上面打开的任何其他子调用在发出scope.complete()时都不会发出中止异常，只有在另一个调用时才会被捕获.尝试进行事务处理，或者当初始transasctionscope发出scope.complete时.

I think the documentation on TransactionAbortedException is a little lacking as to when it can happen.

It DOES NOT happen if you do not do a Scope.Complete on your initial transaction. In other words, failure to execute Scope.Complete means that it will silently exit a transactionscope using block. (Since there is no other way to cancel the transactionscope silently, this is acceptable but should be documented clearly.)
If you need to alert your processes that you are aborting the initial transaction, you should do so by throwing an exception, which will silently close the transactionscope automatically. You may want to have a try/catch wrapping your transactionscope using block to catch these exceptions.

However, if have multiple same level calls to processes that have their own transactionscope using block that join the ambient transaction, you will get the exception if you fail to Scope.Complete on a call. When a subsequent call initiates the transactionscope, it sees a dirty transaction and will issue the transactionabortedexception at that point.
However, if you are nesting calls and the child call does not issue a scope.complete, then any other child call open above it will NOT issue an abort exception when it issues a scope.complete(), it will only be caught if another transaction is attempted or when the initial transasctionscope issues a scope.complete.

Are tips and questions both searched at the same time? If not, then anyone looking for transactionscope exception issues would want to find this in questions in my opinion.
