Head First C#

Second Edition

Wouldn’t it be dreamy

if there was a C# book that

was more fun than endlessly

debugging code? It’s probably

nothing but a fantasy....

Thanks for buying our book! We really

love writing about this stuff, and we

hope you get a kick out of reading it…

…because we know

you’re going to have a

great time learning C#.

Andrew Stellman , despite being raised a

New Yorker, has lived in Pittsburgh twice . The

first time was when he graduated from Carnegie

Mellon’s School of Computer Science, and then

again when he and Jenny were starting their

consulting business and writing their first book for

O’Reilly.

Jennifer Greene studied philosophy in

college but, like everyone else in the field, couldn’t

find a job doing it. Luckily, she’s a great software

engineer, so she started out working at an online

service, and that’s the first time she really got a

good sense of what good software development

looked like.

When he moved back to his hometown, his first

job after college was as a programmer at EMI-

Capitol Records—which actually made sense,

since he went to LaGuardia High School of

Music and Art and the Performing Arts to study

cello and jazz bass guitar. He and Jenny first

worked together at that same financial software

company, where he was managing a team of

programmers. He’s had the privilege of working

with some pretty amazing programmers over the

years, and likes to think that he’s learned a few

things from them.

She moved to New York in 1998 to work on

software quallity at a financial software company.

She managed a team of testers at a really cool

startup that did artificial intelligence and natural

language processing.

Since then, she’s traveled all over the world to work

with different software teams and build all kinds of

cool projects.

When he’s not writing books, Andrew keeps

himself busy writing useless (but fun) software,

playing music (but video games even more),

experimenting with circuits that make odd noises,

studying taiji and aikido, having a girlfriend

named Lisa, and owning a pomeranian.

She loves traveling, watching Bollywood movies,

reading the occasional comic book, playing PS3

games (especially LittleBigPlanet!), and owning a

whippet.

Jenny a nd Andrew have been building so ftware and writing a bout softw are engine ering toget her since they

Intro

Your brain on C#. You’re sitting around trying to learn something, but

whether nude archery is a bad idea.” So how do you trick your brain into thinking

that your life really depends on learning C#?
