c# - How to capture the screen and mouse pointer using Windows APIs?

Question

I'm using the below code to capture the screen in a bitmap. The screen is captured, but I'm unable to get the mouse pointer on the screen. Could you suggest some alternative approach so that the mouse is captured as well?

    private Bitmap CaptureScreen()
    {
        // Size size is how big an area to capture
        // pointOrigin is the upper left corner of the area to capture
        int width = Screen.PrimaryScreen.Bounds.X + Screen.PrimaryScreen.Bounds.Width;
        int height = Screen.PrimaryScreen.Bounds.Y + Screen.PrimaryScreen.Bounds.Height;
        Size size = new Size(width, height);
        Point pointOfOrigin = new Point(0, 0);

        Bitmap bitmap = new Bitmap(size.Width, size.Height);
        {
            using (Graphics graphics = Graphics.FromImage(bitmap))
            {
                graphics.CopyFromScreen(pointOfOrigin, new Point(0, 0), size);
            }
            return bitmap;
        }
    }

[StructLayout(LayoutKind.Sequential)]
struct CURSORINFO
{
    public Int32 cbSize;
    public Int32 flags;
    public IntPtr hCursor;
    public POINTAPI ptScreenPos;
}

[StructLayout(LayoutKind.Sequential)]
struct POINTAPI
{
    public int x;
    public int y;
}

[DllImport("user32.dll")]
static extern bool GetCursorInfo(out CURSORINFO pci);

[DllImport("user32.dll")]
static extern bool DrawIcon(IntPtr hDC, int X, int Y, IntPtr hIcon);

const Int32 CURSOR_SHOWING = 0x00000001;

public static Bitmap CaptureScreen(bool CaptureMouse)
{
    Bitmap result = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, PixelFormat.Format24bppRgb);

    try
    {
        using (Graphics g = Graphics.FromImage(result))
        {
            g.CopyFromScreen(0, 0, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy);

            if (CaptureMouse)
            {
                CURSORINFO pci;
                pci.cbSize = System.Runtime.InteropServices.Marshal.SizeOf(typeof(CURSORINFO));

                if (GetCursorInfo(out pci))
                {
                    if (pci.flags == CURSOR_SHOWING)
                    {
                        DrawIcon(g.GetHdc(), pci.ptScreenPos.x, pci.ptScreenPos.y, pci.hCursor);
                        g.ReleaseHdc();
                    }
                }
            }
        }
    }
    catch
    {
        result = null;
    }

    return result;
}
