goto loops

:-D This is a discussion and I'm not claiming a try-finally block would be a better solution.

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.

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.

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.

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!");xacc.ide

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!
Now your just setting him up to post code in the lounge and getting him flamed for doing so. I'm on to you ;P

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...
You earn your upvote rights by scaring people. ;)

Well if you must know I up voted him for the remark about the 1 vote and the goto the bathroom part. Could be that my sense of humor is a bit off today but I thought it was funny so...

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
