C# 控制台进度条

直接上代码

调用方法

  ProgressBar progressBar = new ProgressBar(Console.CursorLeft, Console.CursorTop, 50, ProgressBarType.Multicolor);
            Compress(100, progressBar.Dispaly);
            Console.WriteLine();
            ProgressBar progressBara = new ProgressBar(Console.CursorLeft, Console.CursorTop, 50, ProgressBarType.Character);
            Compress(100, progressBara.Dispaly);
            Console.WriteLine();

计算方法

  public static void Compress(int val, Func<int, int> dispalyProgress = null) {
    
    

            for (int i = 0; i <=val; i++)
            {
    
    
                if (dispalyProgress != null) {
    
     dispalyProgress(Convert.ToInt32((i / (val * 1.0)) * 100)); }
            
            }
        }
