簡單Console進度條

經常使用控制台來寫小玩意，總希望有個進度條，各種百度，終於簡單實現：

先上進度條幫助類:

 public class ConsoleProgress
    {
        static ConsoleProgress consoleProgress = new ConsoleProgress();
        int top=0;
        int end=0;
        private ConsoleProgress()
        {
            top = Console.CursorTop;
        }
      
         public static ConsoleProgress Intance
        {
            get
            {

                if (consoleProgress == null)
                {
                    lock(new object())
                    {
                        consoleProgress = new ConsoleProgress();
                    }
                }
                return consoleProgress;
            }
        }
        public  void Reset()
        {
            top =Console. CursorTop;
        }
         public void  ShowProgress(int curvalue,string msg)
        {
            if (CursorTop > end && end > 0)
            {
                top = CursorTop;
            }
            Console.SetCursorPosition(100/2-(msg.Length)/2, top);
            //顯示提示信息
            Console.WriteLine(msg);
            Console.SetCursorPosition(100 / 2 - ((curvalue.ToString()+"%").Length) / 2, top+1);
            Console.WriteLine("{0}%", curvalue);
            Console.SetCursorPosition(CursorLeft, top+2);
            Console.WriteLine("┃");
            Console.SetCursorPosition(CursorLeft+1, top+2);
            Console.WriteLine(new string('*',curvalue));
            if (curvalue >= 100)
            {
                Console.SetCursorPosition(curvalue+1, top + 2);
                Console.WriteLine("┃");
                Console.SetCursorPosition(100/2-("操作已完成".Length/2) + 1, top + 3);
                Console.WriteLine("操作已完成");
            }
           end= Console.CursorTop;
        }

    }

2.接下來是調用：

Console.WriteLine("開始進度條控制");
          
            for (int i = 0; i++ < 100;) {
               ConsoleProgress.Intance.ShowProgress(i,  "正則測試");
                Thread.Sleep(50);
            }
           ConsoleProgress.Intance.Reset();//此處用於開啟一個新的進度條，如果不調用此句，則需要有Console.WriteLine()方法被調用后方可正常在用showProgress,否則進度控制會保留上一次調用時的位置：
           // Console.WriteLine("再次測試。。。。。。。。。。。");
            for (int i = 0; i++ < 100;)
            {
               ConsoleProgress.Intance.ShowProgress(i,  "正則測試");
                Thread.Sleep(50);
            }

            Console.ReadLine();

貼出新方法，減小進度條的大小！

 public void  ShowProgress(int curvalue,string msg)
        {
            int total = 30;
            if (CursorTop > end && end > 0)
            {
                top = CursorTop;
            }
            Console.SetCursorPosition(30 / 2-(msg.Length)/2, top);
            //顯示提示信息
            Console.WriteLine(msg);
            Console.SetCursorPosition(30 / 2 - ((curvalue.ToString()+"%").Length) / 2, top+1);
            Console.WriteLine("{0}%", curvalue);
            Console.SetCursorPosition(CursorLeft, top+2);
            Console.WriteLine("┃");
            Console.SetCursorPosition(CursorLeft+1, top+2);
            Console.WriteLine(new string('*',curvalue*30/100));
            if (curvalue >= 30)
            {
                Console.SetCursorPosition(curvalue*30/100+1, top + 2);
                Console.WriteLine("┃");
                Console.SetCursorPosition(30 / 2-("操作已完成".Length/2) + 1, top + 3);
                Console.WriteLine("操作已完成");
            }
           end= Console.CursorTop;
        }
