Instead of posting only the code, you should post the compiler error as well. And please edit the post to format the code section properly.

Is it just me or not but in my day we didn't ask for help at the first hurdle and things were hard then, no internet, remember compiling 16 bit code for the large memory model? We had to find the answers ourselves.
It strikes me it is too easy today to throw an ill-formed/undefined question at CP and expect an answer! What happened to research? What happened to thinking out a problem till you got the the very nub of the issue; because once you know the right question to ask, the answer almost suggests itself.
I mean, linked lists, writing data to a file? Thats really simple stuff that anyone studying a programming course should e able to work out for themselves!

Well, you're right in that it's too easy to just shoot a question into the great Internet Void (tm) and sit back and wait for an answer. One of the things that kill me is the number of questions that claim to be "urgent" yet they're willing to wait for who known how many hours for somebody to notice their question on CP or anywhere else. If it's "urgent" you should be researching it yourself.
Personally, I blame the instructors (since apparently many of these questioners are in classes somewhere). Linked Lists, Reading / Writing Files, this is all Computer Science 1 stuff yet there are no apparent "cookbook answers" or "class tutorials" on this stuff that explains it more fully. You'd think that problems with this stuff would be a predictable outcome so instructors should prepare to instruct on the topic.
And maybe it's the proliferation of "online universities" where there is no physical contact with a "teaching staff" who can provide personalized instruction / answers. Back in the 60's, we had professors who lectured and Teaching Assistants who held other classes and a group of top students (Program Advisors) that sat at desks in the Comp Sci Department and helped fellow students through the homework assignments. I did that job for a couple of semesters. Who provides that service now? Code Project and other such sites.

Ah yes, the good old days when my bedtime reading was the IBM 7090 Principles of Operation manual  Back then, Computer Science wasn't it's own discipline but fell under the Math Department (they didn't know where else to put it). And OJT was the only way anybody got any training.

Back in the 60's my mother was being born. So yeah.
I think that this issue is not only disturbing regarding the fact that people shoot questions on the internet void hoping for an answer to come from the beyond, but as in some cases in which I worked with "experienced" developers which had to ask me, an "I have been programming as a job for 6 months" student how to retrieve items to a .net list.

I get the point you are trying to make, but just because a person is experienced, that does not automatically mean they are experienced in the same disciplines as you.

I find the existence of experienced .net developers that don't know how to retrieve an item from a generic List<t> much more disturbing than that of students that just throw questions on the internet expecting answers from the beyond.
Or perhaps one evolves (using that word loosely) into another.

In my college course, the instructor was around for class, then vanished, leaving 2 or 3 of us to help the rest.

I went back for new training in '04. The instructors were leaving most in the dust, while for me, they were clearly describing something I'd already read in the text books handed out before classes started. It was semi-helpful review for me because I'd cracked open the books and read them as much as I could before class started. I've attended lectures where that person left me in the dust, because I didn't know there was research I could have done ahead of time. In both cases, they weren't of much help to me because I'm more of a visual learner.

That seems a bit unfair - I remember sitting in classes where the instructor explained the material, we had text books, but still some folks would ask for someone to explain what had been explained to them.
There will always be idiots who think that programming is a good job, and they should be able to do it well, and that if they can't, it is someone elses fault.

First because there were very few resources.
Second because it was often difficult to access those resources.
Third there were far fewer people doing it.

Based on that argument every doctor would learn solely by reading books and experimenting.
The reason people didn't use resources long ago was because they didn't exist long ago. The reason that they use them now is because they exist now.

Call me old fashioned but I wouldn't wanted to be treated by a doctor that got his answers off of WebMD or other Medical BBS. Who knows what quality of answer they'd get there.
Nope, I want doctors taught by experienced professors in University Medical Schools, preferably ones attached to real hospitals so the students can do "rounds" with actual doctors. That's how they learn.
That's the analagous discussion to what's here. Would you hire a programmer who said "I learned everything I know from Code Project"? I wouldn't. Have I picked up things here or learned something I didn't know, sure I have. But CP is the *last* place I come to, not the first.

Many hobbyists are more skilled and/or knowledgeable in what they do than professionals.
Why? The hobbyist always loves what he does. The professional loved it once, but now it's just a job that gets bread on the table.
Of course there's many great professionals too, but I wouldn't trust a professional more than I would trust a fanatic hobbyist.
I learned almost everything I know from CP and I spent last saturday fixing code from a Microsoft Certified *insert some titles here*.
And it isn't the first time I fixed her code either.
It's an OO world.

If a doctor posted an 'urgentz pls' post I would go find another doctor.
Actually what they use is a vast library of books and material to check symptoms causes and cures.
What we did in our day was use books too, and work it out ourselves by trying things out.
It seems that experimentation today is dead.

Well, not really! I have done and still do a lot of programming, but my 'day job' was (I am retired) as an Anesthesiologist and Intensivist, and I was generally reckoned a pretty good one. In my speciality, you may have time to research problems you anticipate, but you frequently don't have time to research the unexpected ones, which are often more challenging. The skill comes in being able to anticipate more than 'the average bear' and particularly in rapidly extracting from your prior experiences and/or previous reading/learning the material that is most relevant to the current problem. In less acute specialities, there is more time to think, but putting the gestalt of the patient's presentation (not just signs and symptoms, but also past history and personal circumstances) together into a picture that leads to diagnosis and treatment involves much more than "checking symptoms causes and cures" in "a vast library". Medicine is still at least 40% Art.
