Clue bat needed in Aisle 5! Clue bat needed in Aisle 5!
What do you get when you cross a joke with a rhetorical question? The metaphorical solid rear-end expulsions have impacted the metaphorical motorized bladed rotating air movement mechanism. Do questions with multiple question marks annoy you???

Yes, I saw it.. sighed, and decided to let someone else answer since he apparently didn't believe me :sigh:

Among all the toe-curling flaws in there, these are my two favorites: It's not even a singleton - it's a "noneton": Trying to access the Instance-property will cause a stack overflow due to recursion.. The List<QueryContainer> will be really, really short. Even when fixing the above flaw.. And the answer to the million dollar question: It's supposed to somehow (don't ask me) help with fixing code that is vulnerable to SQL-injection.

The new version[^] still doesn't fix the problem. I'm running out of different ways to explain to him why his approach isn't going to work. :sigh:

I know one remarkably effective way to explain to him: use SQL Injection to delete his database. And every time he puts it back, it goes again. It's cruel. It's nasty. It's probably illegal. But it's what his best mate will do, just to see the look on his face...

After reading the actual questions, I don't think he is trying to fix the actual vulnerability with his code. Instead he may be trying to cheat the test system (by obfuscation) from detecting that there is an SQL injection vulnerability.
The good thing about pessimism is, that you are always either right or pleasently surprised.

As you didn't mark your post as a joke or put a smiley into it I have to assume you're being serious: But my post isn't a programming question.

1. The
Instanceproperty get will overflow the stack due to recursion. 2. TheQueryproperty set and get will both throwNullReferenceException's, sinceContaineris never initialized. 3. The code shouldn't even compile. TheQueryproperty set assignsvaluetoContainer.Query, but sinceContaineris aList<>, it doesn't have aQueryproperty. I'm going to completely ignore the code's stated purpose, which I don't think what they've provided has the faintest hope of meeting.Software Zen:
