Is this called obfuscation?
50-50-90 rule: Anytime I have a 50-50 chance of getting something right, there's a 90% probability I'll get it wrong...!!
If that's obfuscation, I'm not impressed... If I wanted to make it REALLY confusing, I'd do something like this:
const string blarphnik = "51209576120381929170992";
string elkabong = Convert.ToChar(int.Parse(blarphnik.SubString(1,2))- int.Parse(blarphnik /* If I had a pet monkey, I'd name it blarphnik */.SubString(8 /* What a nice number */,1)))
- Convert.ToChar(int.Parse(blarphnik.SubString(18, 2))
/ int.Parse(blarphnik.SubString(6,1) /* Todo: Fix this */));
And then I would publish this as part of a self-help book entitled "How to Drive a Programmer Insane"

Make the constant string a resource and put the constant ints in the config. :-D

No no no... It's harder to hide it that way. With code like this, you want it buried deeply inside a commonly-used DLL in a not-quite-obsolete language, so when you get laid off and the next guy in line decides to rewrite the code and modernize it, they have a heart attack when they see it. At least, That was probably what some of my predecessors were thinking...

No way. Any Basic developer would use either
Chr$(13) & Chr$(10)orvbCrLf, both much more readable than the OP. :)Luc Pattyn [Forum Guidelines] [Why QA sucks] [My Articles]

Reflector showed me this 'gem' in a contractors project:
string cBRK = Convert.ToChar(int.Parse("13")).ToString() + Convert.ToChar(int.Parse("10")).ToString();
this.ReportStatus("93101Bytes" + cBRK + BytesRecieved.ToString() + cBRK + fileSize.ToString() + cBRK);
kind regards, JoFli
My guess is that this is an artifact of Reflector, not of the original coder. I do know that in VB, the Chr() function actually does use Convert.ToChar internally so my guess is that C# does the same. Who knows what Environment.NewLine does internally. I assume that the compiler has in-lined the Chr function, and Reflector has simply given you back what the compiler produced. Anyone with too much free time on their hands and a handy copy of Reflector is invited to experiment to find out what the compiler does with this sort of thing. Reflector is showing you what the code looks like after the compiler has munged it around and played merry havoc with your beautiful code.

OK, there is no Chr function in C# but you know what I mean.

Tcha! The youth and inexperience shows! Every real programmer knows that the best compression method is to use a random number generator with the correct seed to regenerate the uncompressed file - then all you need to do is send the seed. Extending this:
Random rs; const string blarphnik = "51209576120381929170992"; int dontTouchThis = int.Parse(blarphnik.Substring(12,1)); rs = new Random(dontTouchThis); StringBuilder sb = new StringBuilder(2); sb.Append(Convert.ToChar(rs.Next(15))); int dontTouchThisEither = int.Parse(blarphnik.Substring(10,1)); rs = new Random(dontTouchThisEither); sb.Append(Convert.ToChar(rs.Next(15))); string cBRK = sb.ToString();No trees were harmed in the sending of this message; however, a significant number of electrons were slightly inconvenienced.

Oh right, I totally forgot about that... But you have to comment your code to make sure it's legible!
Random rs;
const string blarphnik = "51209576120381929170992";
int dontTouchThis = int.Parse(blarphnik.Substring(12,1));
rs = new Random(dontTouchThis /* That's what SHE said! */);
StringBuilder sb = new StringBuilder(2);
sb.Append(Convert.ToChar(rs.Next(15)));
int dontTouchThisEither = int.Parse(blarphnik.Substring(10,1));
rs = new Random(dontTouchThisEither /* That's what her SISTER said */);
sb.Append(Convert.ToChar(rs.Next(15)));
string cBRK = sb.ToString();Proud to have finally moved to the A-Ark. Which one are you in? Author of Guardians of Xen (Sci-Fi/Fantasy novel)

The correct code in C# is "\r\n" which is
ldstr "\r\n"in MSIL (which is generated exactly like that by the C# compiler)The OP doesn't say that the code was written in C#, it was reverse engineered using Reflector. Reflector is capable of taking code written in VB and decompiling it back into C#. The resulting C# code may look pretty odd, but you will at least be able to see what it is doing.

Well, OK, maybe he's just an idiot. As far as I am aware, Reflector doesn't stop people from writing bad code and will happily decompile bad C# back into bad C#. GIGO, as they say. For what it's worth, the MS .NET Framework implementation of C# Environment.NewLine returns a literal constant "\r\n". No idea what Mono does. So if the contractor wrote this in C#, goodness only knows what was going through his brain. Nothing, probably, if he's like some of the contractors I've known.

No, it hides it in different places; your way has all the information in one place. Plus, using a resource and config makes it brittle -- if someone changes or removes the entries chaos will ensue.

Come to think of it, why are you having to reverse engineer the contractor's project? If he wrote the code while in your employ, I would expect that you would own the intellectual property rights to the code, and normally you would expect to have a copy of the source after his contract ends. Unless you bought this from him as a finished product rather than contracting his time to write it for you. In which case, he owns the copyright and reverse engineering it could be a breach of the licence terms (which normally forbid that sort of thing).

Nah, the point is that everything looks normal from the outside... Then you drill down into the utility functions, and each one is completely illegible. So you've already ported half of the library, and now you don't want to touch it because you're afraid you'll miss something and break an edge condition.

The Chr() = Convert.ToChar() thing makes some sense, but why int.Parse("13") instead of just 13?

Looks like
temp = Chr(13) + Chr(10)gets decompiled intotemp = "\r\n";so the compiler is smart enough to actually make the string when you call Chr with a constant. Environment.NewLine shows up as a property call in Reflector, but the JIT may inline it as a literal string. There's no way Reflector would generate what the OP is seeing unless the code really was that bad.
