Originally(ie. before the revisions history), this answer said you can't pass a value type variable by reference.
I have posted my answer which contradicted the linked one. I have demonstrated that a value type variable can be passed by reference using the ref keyword.
Immediately after that, the OP of the original answer revised his answer. His first few edits were not captured by the revision system. The answer's context was wrong...
While his answer attracted the most attention for being wrong, my answer was correct from the start but I guess it hasn't been seen by others yet as it didn't receive any up votes...
This felt a bit like a case of the fastest gun in the west.
I felt a bit omitted, left out, and not appreciated for the contribution as possibly because the other user has more reputation.
Now, I do understand the SO model: the community can revise questions and answers to provide the best possible source of correct information. This is great and I do like the idea. The fact that the question was wrong attracted the community attention. There have been multiple comments pointing out what was wrong and the answer kept being edited.
If a new user answers and the context of his answer is wrong he is most of the time down voted and comments indicate that his answer is wrong and what is wrong with it. But this case because the user who answered is a higher-rep one nobody actually left a down vote
So, I have left a few comments too which were deleted. I can't reference them as they are not visible to me but I can't understand what drove the person who flagged my comments for moderators attention. I guess it might have been the OP feeling a bit embarrassed as he was being pointed out all the bads.
I haven't offended anyone in my comments and haven't posted any spam or hate speech. I would appreciate an explanation of why my comments have been deleted? Were they not constructive or too chatty?
Please note: the reason I am asking is: I may not fully understand what the comments section is for - and if I don't, I'd like to make sure I do as I contribute quite a lot to Stack Overflow and it would be better for me to actually understand the mechanism so I don't make others feel uncomfortable and don't feel not appreciated myself.
