Question

I need to fill a rectangle with a black to white (transparent) gradient. However, I could only find a GradientBrush class and all examples I found showed smooth transition and I want sharp bars. That’s what I need:

Answer 1

in this code i use picturebox, play with ‘k’ and ‘i’

    private void pictureBox1_Paint(object sender, PaintEventArgs e)
    {
        int k = 20;
        Color mycolor = new Color();
        for (int i = 0; i < 10; i++)
        {
            mycolor = Color.FromArgb(i * k, i * k, i * k);
            SolidBrush mybrash = new SolidBrush(mycolor);
            e.Graphics.FillRectangle((Brush)mybrash, 0 + i * k, 0, k, k);
        }
    }

Good luck!
