C#控制台输出进度和百分比的实例代码

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);
         }
     }
 }
