public class InfiniteProgressBar : Control
{
    private int _value = 0;
    private int _maximum = 100;
    private int _minimum = 0;

        _timer = new Timer();
        _timer.Interval = 50;
        _timer.Tick += Timer_Tick;
        _timer.Start();
    }

    private void Timer_Tick(object sender, EventArgs e)

    protected override void OnPaint(PaintEventArgs e)

        base.OnPaint(e);

        int width = (int)((float)_value / _maximum * Width);
        Rectangle rect = new Rectangle(0, 0, width, Height);

        using (LinearGradientBrush brush = new LinearGradientBrush(rect, Color.Green, Color.GreenYellow, LinearGradientMode.ForwardDiagonal))
        {
            e.Graphics.FillRectangle(brush, rect);
        }
    }
}

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();

        InfiniteProgressBar progressBar = new InfiniteProgressBar();
        progressBar.Location = new Point(10, 10);
        progressBar.Size = new Size(300, 30);
        Controls.Add(progressBar);
    }
}
