代码如下:

	

	 using System;

	 using System.Collections.Generic;

	 using System.Linq;

	 using System.Text;

	

	 namespace ConsoleApplication1

	 {

	     class Program

	     {

	         static void Main(string[] args)

	         {

	             bool isBreak = false;

	             ConsoleColor colorBack = Console.BackgroundColor;

	             ConsoleColor colorFore = Console.ForegroundColor;

	

	             //第一行信息           

	             Console.WriteLine("****** now working...******");

	

	             //第二行绘制进度条背景           

	             Console.BackgroundColor = ConsoleColor.DarkCyan;

	             for (int i = 0; ++i <= 25; )

	             {

	                 Console.Write(" ");

	             }

	             Console.WriteLine(" ");

	             Console.BackgroundColor = colorBack;

	

	             //第三行输出进度           

	             Console.WriteLine("0%");

	             //第四行输出提示,按下回车可以取消当前进度           

	             Console.WriteLine("<Press Enter To Break.>");

	             //-----------------------上面绘制了一个完整的工作区域,下面开始工作

	

	             //开始控制进度条和进度变化           

	             for (int i = 0; ++i <= 100; )

	             {

	                 //先检查是否有按键请求,如果有,判断是否为回车键,如果是则退出循环               

	                 if (Console.KeyAvailable && System.Console.ReadKey(true).Key == ConsoleKey.Enter)

	                 {

	                     isBreak = true; break;

	                 }

	                 //绘制进度条进度                

	                 Console.BackgroundColor = ConsoleColor.Yellow;//设置进度条颜色               

	                 Console.SetCursorPosition(i / 4, 1);//设置光标位置,参数为第几列和第几行               

	                 Console.Write(" ");//移动进度条               

	                 Console.BackgroundColor = colorBack;//恢复输出颜色               

	                 //更新进度百分比,原理同上.               

	                 Console.ForegroundColor = ConsoleColor.Green;

	                 Console.SetCursorPosition(0, 2);

	                 Console.Write("{0}%", i);

	                 Console.ForegroundColor = colorFore;

	                 //模拟实际工作中的延迟,否则进度太快               

	                 System.Threading.Thread.Sleep(100);

	             }

	             //工作完成,根据实际情况输出信息,而且清楚提示退出的信息           

	             Console.SetCursorPosition(0, 3);

	             Console.Write(isBreak ? "break!!!" : "finished.");

	             Console.WriteLine(" ");

	             //等待退出           

	             Console.ReadKey(true);

	         }

	     }

	 }
