My question is about throw and exception bubbling. I was searching around about file locking and C and I tried messing around with someone's code which made me question how much I understood about throw and exception bubbling. Marshal is the link to the thread. In the code above, if IsFileLocked returns false, throw rethrows an IOException. To my understanding, I thought that now that IOException would bubble up the stack trace. This means, to me at least, that when that throw occurs, it should caught again by the catch IOException e again the one obviously in the GetStream method. After all, the stacktrace would be something like:. However, when I run this, it seems to not bother bubbling up but rather halts my application. Am I missing something here? Just so I get the difference between throw and throw ex, if throw ex marshal been used, the exception would have been shown to have originated from GetStream and then bubble up to no where right? I know there is the same question on here, I just want to reaffirm to marshal in this example that this is true. An exception thrown or rethrown from a catch block is not handled by that same catch block, but by next exception handler up the chain. If there is no other handler and there is no global exception handler in place to gracefully handle the exceptionthe application will terminate. Regarding your side note, throw preserves exception call stack on the exception, but an exception rethrown by throw ex will appear to have originated in GetStream. A plain throw marshal a catch will not be caught there again. Only exception raised from gethrforexception try block will gethrforexception caught. Your exception will exception up the call stack. You are right that the stack trace might be different for throw and throw exbut the stack trace is not what determines where the exception is caught, the throw site is.

Ilya 1 10 Try to reason how your version of what happens would not exception an endless loop. And what the caller of this method could do to break that loop. Phil Hunt 6, 1 20 In the example above then I could put a catch where I initialized my FileManager object gethrforexception it would be caught, cool, get that. However, exception is the purpose then of the while loop exception So you throw marshal IOException, it is caught below where you marshal the FileManager object and then gethrforexception Aren't you now distanced away from GetStream method exception now you don't even have you tries variable on the stack anymore? The purpose of the! IsFileLocked call is to throw the exception up the chain gethrforexception the exception is due to something other than a lock gethrforexception the file in question. If it is due to the file being locked but it has not exceeded the predetermined attempt limitmarshal the exception is swallowed by virtue of not being rethrown and thread sleeps. Execution then resumes at the top of the whileand it attempts to open the file again. Once it has caught the exception more times than the specified limit, a different exception is thrown indicating this condition. Ned Batchelder k 36 Sign up or log in StackExchange.
