[英]Exception from thread doesn't bubble up to main thread
Here I start a task: 在这里,我开始一个任务:
System.Threading.Tasks.Task.Factory.StartNew( () =>
RefreshCache(crmClientInfo)).ContinueWith(
previous => RefreshCacheExceptionHandling(previous.Exception),
TaskContinuationOptions.OnlyOnFaulted
);
...and here is my worker: ...这是我的工人:
public void RefreshCache(CrmClientInfo _crmClientInfo)
{
AsyncManager.OutstandingOperations.Increment();
Timer timer = new Timer(10000);
timer.Elapsed += delegate
{
throw new AggregateException("Timeout!");
};
timer.Start();
OtherServices.RefreshCache(crmClientInfo);
AsyncManager.OutstandingOperations.Decrement();
}
If an exception occurs not in the timer definition but somewhere else, the exception bubbles up correctly to RefreshCacheExceptionHandling()
. 如果异常不在计时器定义中而是在其他地方发生,则该异常正确地冒泡到
RefreshCacheExceptionHandling()
。 But if it fires from timer (AgregateException("Timeout!");)
then the thread doesn't break. 但是,如果从计时器
(AgregateException("Timeout!");)
则线程不会中断。 Why? 为什么?
The System.Threading.Timer class makes callbacks on a ThreadPool thread and does not use the event model at all.
System.Threading.Timer类在ThreadPool线程上进行回调,并且完全不使用事件模型。
