Programming C#, Third Edition Jesse Liberty

Aimed at experienced programmers and web developers, the new edition of Programming C# doesn't waste words on elementary programming topics. Instead, this practical book focuses on the features and programming patterns that are new to the C# language and fundamental to the programming of web services and web applications on the .NET platform. Newly updated for version 1.1 of the .NET Framework and Visual Studio .NET 2003, the book features new tips & tricks plus answers to frequently asked questions about C#. Information covered include:

• Classes and objects
• Inheritance and polymorphism
• Operator overloading
• Structs and interfaces
• Arrays, indexers, and collections
• String objects and regular expressions
• Exceptions and bug handling
• Delegates and events
• Development of desktop and Internet applications-- including Windows Forms, ADO.NET and ASP.NET
• Attributes and reflection
• Remoting
• Threads and synchronization
• Streams
• How to interoperate with COM objects

Jesse Liberty's Programming C#, 2nd Edition provides an adept and extremely well-conceived guide to the C# language and is written for the developer with some previous C++, Java, and/or Visual Basic experience. This second edition brings the book up to date, with examples that are guaranteed to run on the shipping version of Visual C# .NET.

It's no secret that many computer books are pretty much devoid of an authorial personality. This title is a winning exception. The author is able to weave in clever examples (using such topics as his own long experience in computing, his dog, Star Trek, etc.) without being coy or getting in the way of presenting real technical information. Liberty's wide experience in computers and general writing skill shows, as he is able to draw on a wealth of examples to move his text forward.

These are a couple of goals at work in Programming C#. First, it's an excellent language tutorial, certainly one of the smartest and best available guides to C# as a language. Early chapters explore basic and obscure language options using inheritance, delegation, interface, and the conventions in C# used to implement these techniques. The middle part of the book turns toward the .NET Framework itself, with two useful (and somewhat introductory) chapters on both Windows Forms and Web Forms, for standalone and Web-based applications, respectively.

Later sections crank up the technical knowledge again with several advanced topics on understanding .NET assemblies and deployment in detail, as well as "reflection" APIs that allow .NET programs to essentially modify their code at run time. (One technique, reflection emit, which literally writes bytecodes, will definitely interest expert readers, though it's unlikely most programmers will need to do this.) Final sections look at the .NET stream classes (rivaled only by Java's for complexity). Liberty looks at basic file and network I/O as well as how objects get serialized and marshaled both for SOAP and Web services and "normal" .NET remoting.

The author's sure hand in navigating the difficult waters of C# and .NET makes for a relatively concise text that is chock-full of useful information on C#. Filled with notably clever and inventive examples, this book is possibly this veteran computer author's best title to date, and it's sure to be a noteworthy resource for experienced developers, as they tackle C# for the first time. --Richard Dragan
