C# in Depth

Fully functional code in snippet form29{}[STAThread]static void Main(string[] args){foreach (string x in new string[] {"Hello", "There"}){Console.WriteLine (x);}}Occasionally extra methods or even types are required, with a bit of code in the Mainmethod to access them. I indicate this by listing the non-Main code, then an ellipsis(...) and then the Main code. So the code in listing 1.20 would turn into listing 1.21.Listing 1.20A code snippet with an extra method, called within the Main methodstatic string[] GetGreetingWords(){return new string[] {"Hello", "There"};}...foreach (string x in GetGreetingWords()){Console.WriteLine (x);}Listing 1.21 Expanded form of listing 1.20using System;public class Snippet{static string[] GetGreetingWords(){return new string[] {"Hello", "There"};}}[STAThread]static void Main(string[] args){foreach (string x in GetGreetingWords()){Console.WriteLine (x);}}Types declared in snippets will be nested within the Snippet class, but that’s veryrarely a problem.Now that we understand what snippets are and what they look like when they’reexpanded, let’s make them a bit more user friendly.Licensed to Rhona Hadida
