Displaying Process Percentage on DOS Screen

I am using 7zip in command line mode.

When the operation takes a long time, the percentage of the process is sometimes displayed.

I wonder if we want to do this with C # / Java, which library to use?

You can type "carriage return", also known as '\r'

to reset "cursor" to the beginning of the line.

System.out.printf("Progress: %3d %% \r", percentComplete);


Now every time you print a string, you go back to the beginning, so the next percentage overwrites the previous one.

no library. You just print System.out.print (not println!) To the console, then send back characters to clear the line.

System.out("Progress 5");
System.out("\b\b\b\b\b\b\b\b\b\b");
System.out("Progress 10");


I haven't done this in awhile, but this should do it.

You can clear the console of bumps ... oh and don't forget that string.format has percentage support ...

using System;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
          var perc = 0.0;
          while(perc <= 1.0)
          {

            Threading.Thread.Sleep(50); //simulate doing some work

            //EDIT:
            //Console.Clear();
            Console.Write(String.Format("{0:P}\r", perc)); //as per suggestion

            perc += 0.01;
          }
          Console.WriteLine("Press any key to exit");
          var exit = Console.ReadKey();
      }

  }

}
