The practicing programmer's DEITEL LIVE-CODE guide toC#
and the powerful Microsoft .NET Framework.
Written for programmers with a background in C++, Visual
Basic, Java or other high-level languages, this book
applies the DEITEL signature LIVE-CODE approach to teaching
programming and explores Microsoft's C# language in depth.
This book presents important C# concepts in the context of
fully tested programs, complete with syntax shading,
detailed line-by-line descriptions and program outputs. The
book features 230 LIVE-CODE programs that contain 26,006
lines of proven C# program code. In addition, the book
includes 402 programming tips that help you build
applications that are portable, reusable and optimized for
performance.
Start with a concise introduction to C # fundamentals,
then rapidly move on to more advanced topics, including
Windows Forms, ADO .NET, ASP .NET, ASP .NET Web services,
network programming and XML processing. Along the way you
will enjoy the Deitels' classic treatment of object-based
and object-oriented programming. When you are finished, you
will have everything you need to build next-generation
Windows applications, Web applications and XML Web
services.
Dr. Harvey M. Deitel and Paul J. Deitel are the founders
of Deitel & Associates, Inc., the internationally
recognized IT content-creation and corporate-training
organization. Together with their colleagues at Deitel
& Associates, Inc., they have written the successful
How to Program Series of college textbooks that hundreds of
thousands of students throughout the world have used to
master C, C++, Java, C#, Visual Basic .NET, Perl, Python,
XML, and other languages.
The DEITEL Developer Series is designed for practicing
programmers. The series presents focused treatments of
emerging technologies, including .NET, J2EE, Web services,
and more. Each book in the series contains the same
LIVE-CODE teaching methodology used so successfully in the
Deitels' How to Program Series college textbooks and
instructor-led, corporate-training courses.
The DEITEL Developer Series includes a wide selection of
books suitable for three types of readers:
- A Technical Introduction Broad overviews of new
technologies for programmers, technical managers and other
technical professionals
- A Programmer's Introduction Focused treatments of
programming fundamentals for practicing programmers and for
novices For Experienced Programmers
- Detailed treatments of language topics for experienced
programmers
