C# teasersHi,
I'm looking for C# brain teasers (or VB.NET): a little piece of code that does something special, or where a little error is. Does anyone has some of these, or links to sites? Thanks! Hello Ludwig,
Use the MS certification preparation matherials for this. They are a good source for such kind of teasers --- WBR, Michael Nemtsev [.NET/C# MVP] :: blog: http://spaces.live.com/laflour "The greatest danger for most of us is not that our aim is too high and we miss it, but that it is too low and we reach it" (c) Michelangelo L> Hi, L> I'm looking for C# brain teasers (or VB.NET): a little piece of code L> that does something special, or where a little error is.

Why does this compile: public class Program{ public static void Main(string[] args){ TypedReference typedReference = new TypedReference(); } } and this not compile: public class Program{ public static void Main(string[] args){ object typedReference = new TypedReference(); } } Alun Harford On Nov 27, 7:14 am, Ludwig <lstuyc***@gmail.com> wrote:
