SqlWorkflowInstanceStore无法访问持久性数据库时没有错误 [英] No error when SqlWorkflowInstanceStore cannot access the persistence DB

问题描述

我有一个工作流，可以通过在WorkflowApplication.PersistableIdle中返回PersistableIdleAction.Persist来使用SqlWorkflowInstanceStore进行持久化.当提供正确的连接字符串时，这可以很好地工作.但是，如果连接字符串不正确，但我没有收到错误，则SqlWorkflowInstanceStore似乎只是默默地失败了.

I have a workflow that I am persisting using the SqlWorkflowInstanceStore, by returning PersistableIdleAction.Persist in WorkflowApplication.PersistableIdle. This works fine when the correct connection string is provided. However, if the connection string is incorrect I do not get an error, the SqlWorkflowInstanceStore seems to just silently fail.

当InstanceStore无法访问数据库或由于其他原因失败时，是否有一种通知方式?

Is there a way to be notified when the InstanceStore cannot access the DB or fails for another reason?

推荐答案

您可以使用跟踪来查看错误.
还应该能够设置实例的OnUnhandledException函数.
类似这样的东西:

instance.OnUnhandledException =(WorkflowApplicationUnhandledExceptionEventArgs e)=> />    {
        Console.WriteLine(e.UnhandledException.Message + Environment.NewLine + e.UnhandledException.StackTrace);
返回UnhandledExceptionAction.Terminate;
   };

谢谢！

You can use tracking to see the errors.
You should also be able to set the OnUnhandledException func of the instance.
Something like this:

instance.OnUnhandledException = (WorkflowApplicationUnhandledExceptionEventArgs e) =>
    {
         Console.WriteLine(e.UnhandledException.Message + Environment.NewLine + e.UnhandledException.StackTrace);
         return UnhandledExceptionAction.Terminate;
    };

Thanks!
