About the Author
Dr. Jack Purdum started his programming career on an IBM 360 mainframe as a graduate student in the 1960s. In the mid - 1970s, he became interested in software development for microcomputers, and he founded his own software development company (Ecosoft, Inc.) in 1977. The company ’ s main product was a statistics package (Microstat) that he wanted to rewrite in a new language called C. Lacking a suitable C compiler, Dr. Purdum ’ s company developed its own MS - DOS - based C compiler and other programming tools. He has been involved with language instruction ever since. Dr. Purdum has authored 15 texts and numerous programming articles and has received several teaching awards. He is currently on the cusp of retirement from Purdue University ’ s College of Technology.

For example, in covering the OOP concept of encapsulation in Chapter 2, he discusses why programmers hide the data properties of an object inside the object. He states: "You hide them for the same reason that kings used to hide their daughters in the castle tower...to keep other people from messing around with them." Later on, when discussing the difference between public and private access specifiers, he points out that using the public access specifier is like locking the princess in the castle tower and then passing out her room key to all the knights of the realm. I don't know about you, but this is easier for me to remember this than some dry explanation that one often reads on encapsulation.
Another strength is the way he anticipates rough spots for the student. One of the most difficult concepts for beginning programmers is the difference between value types and reference types. Dr. Purdum uses a simple explanation of what a symbol table is to discuss l-values and r-values. He then introduces a concept he developed called Bucket Analogy which uses the symbol table concepts to explain the difference between the two classes of data. Even experienced programmers will appreciate this example and how it truly makes the differences clear. He uses a job interview to explain what objects are as well as cookie cutters to explain instantiation. The book does reflect his 25 years of teaching experience.
The material covered is what you'd expect for an introductory text. He also covers relatively new topics like Generics and LINQ. The database chapter even has a fairly complete DBMS. However, the entire theme is to teach OOP and good coding techniques. For example, he'll write a code example that works but then calls it an example of RDC (Really Dumb Code). He then rewrites the code and explains why it is a better solution, especially when writing for a commercial environment. His objective is to teach you good OOP techniques using C# as the vehicle to learn those techniques. His experience owning a software company for 17 years shows through while doing this.
If you want to get a solid introduction to OOP and C#, choosing this book is one of the best choices you can make.
Despite this fact, I found that this book was amazing.
It explains clearly from scratch how to write serious programs using difficult concepts of object oriented programming.
This book is the perfect balance between theory and practice in order to understand perfectly OOP and C# language.
I have read dozens of IT books in my professional life but I need to admit that this book is a must.
Any beginning programmer who follow seriously each step of this book will be able to understand and use OOP and C#.
This book is from my opinion an excellent book for everybody : Beginners as experienced programmers who want to learn C#.
I need to congratulate Mr.Purdum for this masterpiece and I hope he will write another book which will go on building on the strong foundation of this book.
For example a real business software application described step by step would be a great asset for the whole C# community of programmers.
Anyway this book is really a must.
Overall, great book. Just be willing to invest the time to figure out the errors.
The only con I can give is that the examples become increasingly more complicated, compounding most of the book's concepts while often introducing several new ones at once. While this is somewhat expected, I would have liked to see a few additional, simple, examples as new concepts were being introduced (Chapter 12 immediately comes to mind...introducing generics, recursion, and interfaces in one example).
The Wrox website is a great source of info (code samples, forums, etc). I stumbled upon the forums for this particular book one afternoon and found that the author was personally answering nearly every question that was posted. That said, if Dr. Purdum wrote an intermediate C# book, I would snatch it up immediately.
