C#中static void Main(string[] args) 参数示例详解

学习C#编程最常见的示例程序是在控制台应用程序中输出Hello World！ using System; namespace DemoMainArgs { class Program { static void Main(string[] args) { Console.WriteLine(Hello World！); Console.ReadLine(); } } } static:是将Main方法声明为静态，是应用程序的入口。 void:说明main方法不会返回任何内容。 string[]args：这是用来接收命令行传入的参数。string[]是声明

你可以尝试使用Lambda表达式来简化代码，如下所示： public class Main { public static void main(String[] args) { BookShelf bookShelf = new BookShelf(4); bookShelf.appendBook(new Book("Around the World in 80 Days")); bookShelf.appendBook(new Book("Bible")); bookShelf.appendBook(new Book("Cinderella")); bookShelf.appendBook(new Book("Daddy-Long-Legs")); bookShelf.forEach(book -> System.out.println(book.getName())); } }
