Answers to C# Quiz - Need for speed

You can find the original quiz over here . There have been lots of great answers, thanks to all readers! The bottom line however is that one should be careful when doing performance optimizations; in much cases the code doesn't become cleaner (even the opposite).

Last week, I introduced C# 2.0 to a few academic people who had prior exposure to C, C++ and Java. Does language matter is an often heard question.

C# Quiz - Need for speed

This quiz was derived from an old piece of code I reviewed for a student's project somewhere in the past. Actually, I was doing some perf-related work today, so I thought it might be useful to have a little quiz around this. Below is the code (reduced in size) of a matrix implementation in C#. Using...

C# Quiz - call versus callvirt

A little different quiz approach today; starting from IL :-). The question is pretty simple: when does the C# compiler emit a call instruction instead of a callvirt instruction?

There were quite some interesting discussions around the why and how of properties, indexers, operator overloads, events, delegates, attributes, etc compared to "equivalents" in Java. I won't repeat this discussion...

Answers to C# Quiz - "Something weird"

I told you guys it was trivial :-). First of all, there's nothing wrong with the code: 1 class Weird 2 { 3 static void Main() 4 { 5 int i = 1 ; 6 for (i = 0 ; i < 100 ; i ++ ) 7 { 8 System.Console.Write( ' . ' ); 9 } while (i <= 100 ); 10 } 11 } Why? C# doesn't care about spacing; it could have...
