goto loops

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...

What do you not understand about "Please do not post programming questions here"?

IMHO this is not a programming question.

OK - to clarify. What you have asked here is more of a programming philosophy question than a programming question. Others ask these in the Lounge and get away with them so I don't see why you shouldn't. I have never encountered a situation in .NET where a goto makes my job easier. Generally, a well structured application with small, self-contained methods should have no need for a goto. When I see them, it's generally an indication that somebody has landed themselves in an architectural muddle and they can't see the way out of the morass. This is generally when they have loops nested within loops nested within loops. The way I tend to look at this, if you've got yourself this deep into loopfuggery, it's an indication that you are using the wrong loops.

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.

Never used it in c#.

That you call them "goto loops" speaketh volumes. Like every other programming tool, the goto has its uses. It is mostly used underwater, by the things you use instead of gotos. It can also, like every other programming tool, be used stupidly by bad programmers.

Yep, I was taught to avoid gotos also cause they make the code harder to read and ifs, selects, whiles and fors can all get you the same results and they are easier to read. However I have noticed some of the newbies using gotos here (in my place of work) also. It appears they have come back into fashion. Maybe because they were eradicated so well that the newbies aren't being taught how bad code can get with injudicious use of gotos?

Every now rare once and a while (althought it has been probably close to a decade for me ;) ) it can be useful. The common clause is that it is probably better to analyze your code and see if it would not be cleaner and easier to read another way.

Maybe they are reading unoptimised reflector code. Goto is commonplace there.

Ok, surely the first and last examples here can be done using return in a try-finally block?

No serious programmer uses a
goto. EDIT (After the 1 vote)---------------- Okay - maybe we all do - when wegotothe bathroom....45 ACP - because shooting twice is just silly

NEVER, EVER use GoTo - It's generally very bad programming and makes the code harder to read. That goes for both C# and VB.NET.
While advice like this is doled out to inexperienced developers, once you reach a certain level of proficiency it becomes poor or useless advice. I was told by uni lecturers as I was doing my degree that inexperienced developers can try to use gotos as a means for everything, rather than thinking about more concise loop construct which is why they're advised to steer clear. However, this doesn't make the advice sound - it's more of a teaching aid to guide in the right direction. To give a specific example, using a goto as an exit clause in a set of nested 'for' loops is probably the most efficient way of forcing an early exit, and is probably the easiest to read. Goto is perfectly acceptably - just try not to overuse it.
