Windows Workflow Foundation，异常和重试？
我有一个包含许多活动的连续工作流程。 其中一项活动需要访问我的付费 S3 帐户。 它工作正常，但要小心，我想确保它可以处理意外情况，例如“找不到主机”或超时等。
所以..我通常会将代码放在 TRY / CATCH 中。 很好..但我不确定我应该如何处理工作流程..因为如果代码未能正确完成，则工作流程的其余部分不应发生（基于此工作流程的逻辑）。
因此，我想重试连接几次..如果最终失败，请调用电子邮件活动并终止工作流程。
任何人都可以提出任何建议、视频或屏幕链接来帮助展示最佳实践是什么？
干杯！
I have a sequential workflow with a number of Activities. One of these activities needs to access my paid S3 account. It works fine, but to be cautious, I would like to make sure it can handle unexpected situations, such as 'Host not found' or some timeout, etc.
So .. i would normally put the code inside a TRY / CATCH. That's fine .. but i'm not sure of what i should do with the workflow .. because if the code fails to complete correctly, the rest of the workflow shouldn't occur (based on the logic of this workflow).
So, i wanted to maybe retry the connect a few times .. and if that finally fails, call an Email Activity and terminate workflow.
Can anyone make any suggestions, links to vid's or screenies that help show what is the best practice for this?
cheers!

查看
FaultHandlerActivity，用于处理FaultType属性指定类型的异常。 有关 WF 中错误处理的一些链接：另一种方法是使用
Activity.HandleFault方法，当在活动执行的上下文中引发异常时调用该方法。Take a look at the
FaultHandlerActivity, which is used to handle an Exception of the type specified by theFaultTypeproperty. Some links about error handling in WF:Another way is to use the
Activity.HandleFaultmethod, which is called when an exception is raised within the context of the execution of your activity.
