C# get fast screenshots or application frame

Question

I need fast to get the image from a game. And i try with simple screen shots like this:

        Rectangle bounds = Screen.GetBounds(Point.Empty);
        using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
        {
            using (Graphics g = Graphics.FromImage(bitmap))
            {
                g.CopyFromScreen(Point.Empty, Point.Empty, bounds.Size);
            }
            bitmap.Save("Screen.bmp");
        }

but i don't know why if i get the screen shot i can get another after 10 sec... need a way to take faster images. It would be even better to take the game frames.

What is the current bottleneck? Does it hang at copy, or the save perhaps? Perhaps you could save at a later time. — TJHeuvel, Jun 15 '12 at 13:26

One way to improve performance is to execute the save asynchronously using Task.Factory.StartNew — Panagiotis Kanavos, Jun 15 '12 at 13:31

I would consider threading this off.

Saving the bitmaps in memory and on a seperate thread as items go to your BitMap Stack you can just pop them off one at a time and save to disk.

This way you can keep taking as many screenshots as you want

Avoid this line

using(Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))

on every call to save screen shot. Just initialize it once as a global variable and see the magic.

If you want to grab more than one screenshot, you might need to consider a "frameCounter" and add it up per cycle.
