There’s a TargetSite property on System.Exception that should come in handy. Gets the method that throws the current exception. In your case, you probably want something like: catch (Exception ex) { MethodBase site = ex.TargetSite; string methodName = site == null ? null : site.Name; … } It’s worth pointing out some of the issues … Read more
Try looking at Double.TryParse() if you are using .NET 1.1/2.0/3.0/3.5/4.0/4.5
Firefox interprets function statements differently and apparently they broke declaration hoisting for the function declaration. ( A good read about named functions / declaration vs expression ) Why does Firefox interpret statements differently is because of the following code: if ( true ) { function test(){alert(“YAY”);} } else { function test(){alert(“FAIL”);} } test(); // should … Read more
You’ll have to make this separate try blocks: try: code a except ExplicitException: pass try: code b except ExplicitException: try: code c except ExplicitException: try: code d except ExplicitException: pass This assumes you want to run code c only if code b failed. If you need to run code c regardless, you need to put … Read more
traceback.format_exc() or sys.exc_info() will yield more info if that’s what you want. import traceback import sys try: do_stuff() except Exception: print(traceback.format_exc()) # or print(sys.exc_info()[2])
async function errorTest() { /* … */ } try { errorTest() } catch(err) { console.log(“OUTSIDE ERROR!” + err) } Because errorTest is async, it will always return a promise and it is never guaranteed to finish execution before the next statement begins: it is asynchronous. errorTest returns, and you exit the try block, very likely … Read more
In short, the check is way faster. You should use the check because: Exceptions are EXPENSIVE! A stack trace must be created (if used, eg logged etc) and special flow control handled Exceptions should not be used for flow control – Exceptions are for the “exceptional” Exceptions are the code’s way of saying “I can’t … Read more
Divide by zero is valid for floating point numbers. 1/0 yields Infinity. (-1)/0 yields -Infinity. 0/0 yields NaN. These “numbers” are properly defined in IEEE 754. Integer division by zero, on the other hand, throws because one cannot represent infinity as an int.
Yes, that is valid C++. One purpose i’ve found for it is to translate exceptions into return values, and have the code translating the exceptions in return values separate from the other code in the function. Yes, you can return x; from a catch block like the one you showed (i’ve only recently discovered that, … Read more
