How to draw a pixel in a form (like putpixel() in C) with DotNet?

Thanks!

Hi Raju,

For lines, circles, etc. use GDI+, as follows:

private void Form1_Paint(object sender, System.Windows.Forms.PaintEventArgs e) {
Pen p = new Pen(Color.Yellow, 5);
Graphics g = e.Graphics;
g.DrawLine(p, 10, 10, 90, 90);
}

But you probably know that already. I don't see anything in the help for
individual pixels, but you can always place an empty PictureBox on the form,
then create a blank Bitmap object inside it and use Bitmap.SetPixel.

Thanks Fergal,

Yeah I already knew about drawing lines, circles using GDI+. But I was trying
to use my own drawing algorithms in C# which needs C's putpixel equivalent.
Using bitmap as you suggested will work, but it might not be efficient to use
in such algorithms.

I'd appreciate for any better solution.
