Abstract

CHAPTER 3 ■ ■ ■ C# Quick Start and C# Development T his chapter presents a quick overview of the C# language. This chapter assumes a certain level of programming knowledge and therefore doesn’t present very much detail. If the expla- nation here doesn’t make sense, look for a more detailed explanation of the particular topic later in the book. The second part of the chapter discusses how to obtain the C# compiler and the advantages of using Visual Studio .NET (VS .NET) to develop C# applications. Hello, Universe As a supporter of SETI, we thought it’d be appropriate to do a “Hello, Universe” program rather than the canonical “Hello, World” program: using System; class Hello public static void Main(string[] args) Console.WriteLine("Hello, Universe"); // iterate over command-line arguments, // and print them out for (int arg = 0; arg < args.Length; arg++) Console.WriteLine("Arg {0}: {1}", arg, args[arg]); As discussed earlier, the .NET runtime has a unified namespace for all program informa- tion (or metadata). The using System clause is a way of referencing the classes that are in the System namespace so they can be used without having to put System in front of the type name. 1. Search
