如何重新运行BackgroundWorker
我需要在 DoWork 期间捕获错误，如果错误属于某种类型，请重新运行相同的 BachgroundWorker。已尝试取消它并在 Completed 事件期间调用 RunWorkerAsync()，但没有成功（出现异常，表明我的后台工作对象已取消）。
I need to catch error during DoWork and if the error is of some type- re-run the same BachgroundWorker. Already tried to cancel it and call RunWorkerAsync() during Completed event, but no luck(exception appears saying that my backgroundworker object was canceled).

我猜测 Bgw 仍处于错误/已取消状态，直到完成事件完成。
几个选项：
Bgw 本身并不昂贵，因此重用特定实例没有什么意义。线程来自ThreadPool。
I would guess that the Bgw remains in the Error/Canceled state until the Completed event has finished.
A few options:
A Bgw itself is not expensive so there is little point in reusing a specific instance. The threads come from the ThreadPool.
