This simple method captures the current screen image into a .NET Bitmap object.

There is no need for a third party DLL. This simple method captures the current screen image into a .NET Bitmap object.

    private Image CaptureScreen()
    {
        Rectangle screenSize = Screen.PrimaryScreen.Bounds;
        Bitmap target = new Bitmap(screenSize.Width,screenSize.Height);
        using(Graphics g = Graphics.FromImage(target))
        {
            g.CopyFromScreen(0,0,0,0,new Size(screenSize.Width,screenSize.Height));
        }
        return target;
    }

I am sure you can figure out how to capture a smaller portion of the screen, if that is needed :-).
