Windows API'lerini kullanarak ekran ve fare işaretçisi nasıl yakalanır?

Question

Ekranı bir bitmapte yakalamak için aşağıdaki kodu kullanıyorum. Ekran çekildi, ancak ekranda fare imlecini alamıyorum. Farenin de yakalanması için alternatif bir yaklaşım önerebilir misiniz?

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; 
}
