C# Console Progress

ConsoleProgress.cs

public class ProgressBar
{
    private int _lastOutputLength;
    private readonly int _maximumWidth;

    public ProgressBar(int maximumWidth)
    {
        _maximumWidth = maximumWidth;
        Show(" [ ");
    }

    public void Update(double percent)
    {
        // Remove the last state           
        string clear = string.Empty.PadRight(_lastOutputLength, '\b');

        Show(clear);

        // Generate new state           
        int width = (int)(percent / 100 * _maximumWidth);
        int fill = _maximumWidth - width;
        string output = string.Format("{0}{1} ] {2}%", string.Empty.PadLeft(width, '='), string.Empty.PadLeft(fill, ' '), percent.ToString("0.0"));
        Show(output);
        _lastOutputLength = output.Length;
    }

    private void Show(string value)
    {
        Console.Write(value);
    }
}

Program.cs

static void Main(string[] args)
{
    var progress = new ProgressBar(60);
    for (int i = 0; i < 101; i++)
    {
        progress.Update(i);
        System.Threading.Thread.Sleep(50);
    }

    Console.WriteLine();
}

It's useful! I even on older versions! Love it
