Here’s an interesting question. I have a system that attempts to run some initialization code. If it fails, we call the deinitializer to clean everything up.

Because we call the deinitializer in exception handling, we run the risk that both initialize and deinitialize will fail, and hypothetically, it now seems that we have to throw two exceptions.

It seems pretty unlikely that we will, though. So what happens and what should the code do here?

      try { /* init code here */ }               catch (Exception ex)       {          try          {             _DeinitializeEngine();          }          catch (Exception ex2)          {             throw new OCRException('Engine failed to initialize; ALSO failed to deinitialize engine!', ex2);          }          finally          {             throw new OCRException('Engine failed to initialize; failed to initialize license!', ex);          }       }

  1. If your clean up code is failing and you cannot leave the application in a clean and known state I would let the exception go unhandled (or catch it with the UnhandledException event to log it) then close the application.

    Because if you can’t handle the first exception, what point is there in catching the second exception?
