后台工作者异常处理(Background worker exception handling)

我对如何处理异常有些困惑。

我有一个后台工作线程运行一些长时间运行的进程。 我的理解是,如果后台工作线程发生异常,代码仍然会以RunWorkerCompleted方法结束。

void bgWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
    {

        if (e.Error != null)
           throw e.Error;

如果是这种情况,那么围绕bgWorker.RunWorkerAsync()放置一个try catch块就有任何意义。 打电话,我假设不是?

我想重新抛出在RunWorkerCompleted方法中捕获的异常,我如何在不丢失堆栈跟踪的情况下做到这一点 - 我上面正确的是什么? 我在重新抛出一个异常时读到了你,你应该使用“throw”?


I am slightly confused on how to deal with an exception.

I have a background worker thread that runs some long running process. My understanding is if an exception occurs on the background worker thread the code will still end up at the RunWorkerCompleted method.

void bgWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
    {

        if (e.Error != null)
           throw e.Error;

If this is the case is there any point in putting a try catch block around the bgWorker.RunWorkerAsync(); call, I assume not?

I want to rethrow the exception that is caught in the RunWorkerCompleted method, how can I do this without losing the stack trace - is what I have above correct? I read that you when rethrowing an exception you should just use "throw"?

Django在内部使用UTC时间。 TIME_ZONE将被用于“您的观点和模型”( https://docs.djangoproject.com/en/1.9/ref/settings/#std:setting-TIME_ZONE

你从2016-01-11 00:00 CET开始,即2016-01-10 23:00 UTC ! 您的日期时间已正确保存到数据库并在以后进行了恢复,因此所有内容都按预期工作。


Django uses UTC time internally. TIME_ZONE will be used "for your views and models" (https://docs.djangoproject.com/en/1.9/ref/settings/#std:setting-TIME_ZONE)

You started with 2016-01-11 00:00 CET, which is 2016-01-10 23:00 UTC! Your datetime was correctly saved to the database and later restored, so everything is working as expected.
