    Wow - looks like someone didn't agree with you, and didn't say why.

      No serious programmer uses a goto. EDIT (After the 1 vote)---------------- Okay - maybe we all do - when we goto the bathroom...

      Strange - when I post a comment along those lines, I get downvoted, but when you do it gets upvoted. Makes me think that some people here go more for the person than the message! Isn't the first time I have noticed that, though...

        Wasn't me even though I don't agree with you. But since you are so dead set I'm wrong, I challenge you: Show me ONE piece of code where a GoTo has a meaningful use!

                      I got 1-voted, and probably from the same person that 1-voted you. I edited it because I thought that's why I was 1-voted - I had neglected to mention the one valid goto everyone uses. Of course, the 1-voters can also goto hell for all I care.

                            I think the nested 'for' loop example is meaningful enough: for (int i = 0; i < I_BOUND; i++) { for (int j = 0; j < J_BOUND; j++) { if (MyTestingFunction(i, j, k)) { goto LoopExit; } } } LoopExit: Steve McConnell gives a few other examples here[^]. To be clear, I'm not saying there aren't other ways of doing this (as there clearly are), and I don't believe there are any situations where using a goto provides funtionality above and beyond other native constructs (though am willing to be proved wrong!). I just don't agree that you can categorically state that use of goto is *always* wrong.

                              It's probably easier, but I still don't think it's a good use in this case. Sort of like exiting a room through the window. I'm not an expert on this, but can you be sure that jumping out of a nested loop like that doesn't leave something not cleaned up properly, stack e.g.?

                                It depends on the context - if MyTestingFunction() is expensive to run then an intelligent way to exit the loop early is a pretty good reason, especially if the bounds of the data structure being traversed are very large. The variables in the loops are scoped by the braces so by the time the exit label is hit, the variables are out of scope and the GC can do its thing. Assuming that MyTestingFunction() is stateless and isn't dealing with unmanaged resources, I don't believe there's a memory leak issue here.

                                  Do you use goto in C# ? Where do you find it usefull or not usefull ? i had never used goto in C# but now when i just saw that a collegue uses this very often, I start wondering.. :-? tell me...

                                    I have used goto in C# when breaking out of nested loops, and rarely in switch blocks to avoid copying one case to the end of some other case (copypasta is worse than goto IMO). And I will hear no "nested loops should be refactored anyway" - it was performance code and performance code is not meant to look nice. In assembly I use the equivalent of goto all the time. There is no alternative.

                                      It isn't a programming question. He's just asking for opinions about usage of a statement (warning: related to programming). Ya know? Other than important things like football, bullshit politics, stiupid dradunk bdahbble, cricket, etc., people should be let free to discuss something related to programming now and then.

                                      It's time for a new sig. Seriously.

                                        to greater effect than the other solutions he provided, but not greater than real good solutions. As you started to point out, you can write his example in perfectly good code without requiring to the goto instruction. IMHO, this blog entry is rather poor.

                                        There are always other solutions. The blog was pointing out the in rare circumstances goto is the best solution....if you define best as also the simplest solution. And yes, goto can be abused just like any other element in any language. I've seen multiple inheritance abused far more than goto's.
