Progress bar in console application

I was also looking for a console progress bar. I didn’t find one that did what I needed, so I decided to roll my own. Click here for the source code (MIT License).

Features:

• Works with redirected output

  If you redirect the output of a console application (e.g., Program.exe > myfile.txt), most implementations will crash with an exception. That’s because Console.CursorLeft and Console.SetCursorPosition() don’t support redirected output.

• Implements IProgress<double>

  This allows you to use the progress bar with async operations that report a progress in the range of [0..1].

• Thread-safe

• Fast

  The Console class is notorious for its abysmal performance. Too many calls to it, and your application slows down. This class performs only 8 calls per second, no matter how often you report a progress update.

Use it like this:

Console.Write("Performing some task... ");
using (var progress = new ProgressBar()) {
    for (int i = 0; i <= 100; i++) {
        progress.Report((double) i / 100);
        Thread.Sleep(20);
    }
}
Console.WriteLine("Done.");
