学习获取终端输入的参数并且打印，以及使用循环。

using System;public class CommandLine{   public static void Main(string[] args)  // 需要参数   {       // The Length property is used to obtain the length of the array.        // Notice that Length is a read-only property:       Console.WriteLine("Number of command line parameters = {0}",          args.Length);       for(int i = 0; i < args.Length; i++)  // 循环       {           Console.WriteLine("Arg[{0}] = [{1}]", i, args[i]);       }   }}

 

using System;public class CommandLine2{   public static void Main(string[] args)   {       Console.WriteLine("Number of command line parameters = {0}",          args.Length);       foreach(string s in args)       {          Console.WriteLine(s);       }   }}
