Release Team[oR] 2001 [x] Programming A Programmer's Introduction to C# by Eric Gunnerson ISBN: 1893115860 Companion Web Site This book takes the C programmer through the all the details—from basic to advanced-- of the new Microsoft C# language. Table of Contents Colleague Comments Back Cover Synopsis Written as an introduction to the new C#, this guide takes the experienced C programmer a few steps beyond the basics. It covers objects, data types, and flow control, and even delves into some background on the new Microsoft NET Frameworks environment. Keeping in mind that this is for those familiar with C (and even Java), the book goes into some of the advanced features and improvements found in this new language. It also offers a comparison between C#, C++, Visual Basic, and Java.
