I remember reading somewhere that .NET compilers optimize static string concatenation. But maybe I'm wrong.

But this is not a static string concatenation because Convert.ToChar(34).ToString() isn't a constant, but a method call.
Only string concatenations that don't cause a compile error in const declarations are optimized by the compiler.
E.g.
const string name = "Bob";
const string test = "Hello " + name; // valid, concatenation happens at compile time
const string test2 = "Hello" + Convert.ToChar(32).ToString() + "Bob"; // invalid

He most probably didn't understand what he was doing, that's sad.

Placing an "@" does not produce any error for line break.
e.g. the following code would produce an error.
string x = "Blah blah blah"
+ Convert.Tochar(37) .ToString();
But the following would not
string x = @"Blah blah blah"
+ Convert.Tochar(37) .ToString();
(I am writing this without testing. So feel free to let me know if I am wrong.)

as an assignment, i asked for a program that we've all been through, a function that returns weather or not a given number is prime.
in one case, i was given the following :
if(num== 1 || num== 2 || num== 3 || num== 5 || num== 7 || num== 11 || num== 13 || num== 17 || num== 19 || num== 23 || num== 29 || num== 31 || num== 37 || num== 41 || num== 43 || num== 47 || num== 53 || num== 59 || num== 61 || num== 67 || num== 71 || num== 73 || num== 79 || num== 83 || num== 89 || num== 97 || num== 101 || num== 103 || num== 107 || num== 109 || num== 113)
{
return true;
}
else
{
return false;
}
when i asked him why he stopped at 113
(since it was the only thing i thought of asking) he said, in a tired voice,
"I couldn't think of any more numbers"
do you, or do you not feel sorry for him?

well then.
and i felt sorry for him having to find them on his own.
well observed!

13 is considered bad unlucky number. Is 113 fall under this category also?

Interesting how many unproved conjectures there are.

That would be one heck of a long list if they (the original coder or Wikipedia) attempted listing all the primes

And, in addition to being very limited in the range of input values, the result isn't correct, either.

1 is not a prime number, by definition.

It is qualified as Unique Number right?

And any of the following things would have happened for sure:
1) Typing the if-else clause for 10000 numbers, he would broken the keyboard.
2) Typing the if-else clause for 10000 numbers, he would have broken down and ambulance should have been requested.
It is an unnecessary headache, at least in this case right?

Ask him to write a function that returns weather or not a given number is even

Well funny you should mention that, since it was asked previously.
Amazingly enough, most knew the *hidden* patterns of even numbers.
Or they heard me say modulus, between all the words that sent them to sleep.

And for sure, the developer would written the code which would have thrown System.StackOverFlowException

How about a function that returns whether a number is an integer?

Nah, since for most of their test data it returned good results.

Waaaay back in college, in my first Pascal class, we were assigned the task of writing a program to perform the "Sieve of Eratosthenes"... but the assignment quoted a formula to use... which was faulty (of course). I don't know what the other students did, but I headed to the library.
If I ever teach (and I'd like to) I would assign the problem with extra credit to whomever builds the largest sieve. Wouldn't this be a good Friday programming quiz?

I miss those. 
I leave my office a bit early on Friday evenings and don't get to see the Friday quizzes because they're posted later in the day. (I don't have a computer at home.)
Cheers,
