    Yes - I scored the post in a way I saw fit and gave reasons in the response I posted. Which I believe is actually the polite way of doing things!

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

        This article/blog[^] Shows situations where goto statements can be used to greater effect than other soloutions although I must confess I can see better ways to code some of the examples, that the author ignores. I was always taught to avoid goto's at all costs and have always stuck to this advice, however, like you, I have noticed collegues use them a lot.

        Funny how no-one even the comments could come up with a really good alternative (I agree for simplicity, the && is approach is best). How would I do it?

        bool Do(params Func<bool>[] args)
        {
        foreach (var a in args)
        if (!a())
        return false;
        return true;
        }
        ...

        if (Do(Step1, Step2, Step3, Step4, Step5, Step6, Step7))
        Console.WriteLine("Brillant!");

          We did not give up. We made a tactical counter march and just never had any strategic opportunity to go back to the front.

            I was thinking about a similar construction with function pointers, but I know no C#. This is a very cool solution.

              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!

                  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...

                                  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 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.

                                        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 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.?
