 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 = truebreak;

                }

                //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);

        }

    }
