using System;
namespace ConsoleApplication1
{
    class Program
    {
        static int maxValue = 10000;    // 表示數值最大值
        static int factor = 2;          // 表示 ProgressBar 每格 % 數

        static void Main(string[] args)
        {

            {
                Console.SetCursorPosition(0, 0);
                int process = (int)(((float)i / maxValue) * 100 / factor);
                Console.WriteLine(" ****** ConsoleApp ProgressBar Style 1 ... ****** ");
                ProgressBarStyle1(process);

                Console.WriteLine("\n ****** ConsoleApp ProgressBar Style 2 ... ****** ");

                Console.WriteLine(string.Format("\n目前進度：{0}% ({1}/{2})", process * factor, i, maxValue));
                if (i == 5000) { Console.ReadKey(); }
            }
            Console.WriteLine("Press any key to exit ..");
            Console.ReadKey();
