Visual C# 2010 Recipes A Problem-Solution Approach 代码一 —— Create a Console Application from the Command Line

ConsoleUtils.cs

using System;namespace Apress.VisualCSharpRecipes.Chapter01{ public class ConsoleUtils { // A method to display a prompt and read a response from the console. public static string ReadString(string msg) { Console.Write(msg); return Console.ReadLine(); } // A method to display a message to the console. public static void WriteString(string msg) { Console.WriteLine(msg); } // Main method used for testing ConsoleUtility methods. public static void Main() { // Prompt the reader to enter a name. string name = ReadString("Please enter your name : "); // Welcome the reader to Visual C# 2010 Recipes. WriteString("Welcome to Visual C# 2010 Recipes, " + name); } }}

 

 

HelloWorld.cs

using System;namespace Apress.VisualCSharpRecipes.Chapter01{ class HelloWorld { public static void Main() { ConsoleUtils.WriteString("Hello, world"); Console.WriteLine("/nMain method complete. Press Enter."); Console.ReadLine(); } }}

 

一个放大版的HelloWorld，就不知道如果把它放到入门第一堂课上讲，会不会被学生轰下去。
