Essential C# 2.0 (Paperback)
暫譯: C# 2.0 精要 (平裝本)

Description

“Essential C# 2.0 pulls off a very difficult task. The early chapters are comprehensible by beginning developers, while the later chapters pull no punches and provide the experienced developer with the detailed information they need to make the most of C# 2.0. Starting with the first chapter, Mark has successfully interwoven tidbits of information useful to even the most advanced developer while keeping the book approachable.”
—Chris Kinsman, chief architect, Vertafore, Microsoft Regional Director

“How refreshing! This book deals with C# thoroughly, rather than skimming over the whole .NET framework. It is valuable to newcomers and professionals alike.”
—Jon Skeet, C# MVP

“Essential C# 2.0 is a one-stop shop for an experienced programmer looking to ramp up on one of the hottest languages around today. Mark delivers an intelligent and detailed tour of C#, providing newcomers to the language with a solid foundation of skill on which to build their next generation of applications.”
—Stephen Toub, technical editor, MSDN Magazine

“This book provides complete, up-to-date coverage of all the programming constructs in C#. Masterfully organized, it allows beginning programmers to get on board and leads more experienced programmers into the world of structured programming. Because of its unwavering focus on the essential programming constructs of C#—such as generics, delegates, and much more—this book is indispensable. For programmers who want to solve their day-to-day programming issues using the latest features this modern programming language has to offer, this book is indispensable.”
—Narendra Poflee, IT integration specialist, Itron Inc.

“Essential C# 2.0 is an ideal book for all programmers interested in C#. If you are a beginner, you will quickly learn the basics of C# programming and become familiar with the concepts. The flow of the text is easy to follow and does a great job of not repeating concepts that have already been covered. For the experienced programmer, this book has priceless nuggets embedded within its pages, making it a great read for programmers who are already familiar with C#. This will be a book that I will keep next to my computer for years to come.”
—Michael Stokesbary, software engineer, Itron Inc.

Essential C# 2.0 is a clear, concise guide to C#—including the features new to C# 2.0. The book clearly presents material for beginners and experts and provides contrasts and comparisons between C# and other languages. The C# language is covered comprehensively and each important construct is illustrated with succinct code examples. Complete code examples are available online. Mark Michaelis has organized the material for quick access. Graphical “mind maps” at the beginning of each chapter show what material is covered and how each topic relates to the whole.

Following the C# introduction, readers will learn about

• C# primitive data types, value types, reference types, type conversions, and arrays
• Operators and control flow, loops, conditional logic, and sequential programming
• Methods, parameters, exception handling, and structured programming
• Classes, inheritance, structures, interfaces, and object-oriented programming
• Well-formed types, operator overloading, namespaces, and garbage collection
• Generics, collections, and iterators
• Reflection, attributes, and declarative programming
• Threading, synchronization, and multi-threaded patterns
• Interoperability and unsafe code
• The Common Language Infrastructure that underlies C#

C# 2.0 has a multitude of new features that make the language even more powerful, productive, and efficient. These new features are thoroughly covered in this book. A separate appendix on C# 2.0 topics helps readers quickly find new features of the language.

Whether you’re just starting out as a programmer, are an experienced developer looking to learn C#, or are a seasoned C# programmer interested in learning the new features of C# 2.0, Essential C# 2.0 gives you just what you need to quickly get up and running writing C# applications.
