怎样将光标画到屏幕位图上

Question

private Bitmap GetDesktopBitmap()
{
         
           
  
                       
Size DesktopBitmapSize = GetDesktopBitmapSize();
Graphics Graphic = Graphics.FromHwnd(GetDesktopWindow());//从窗口的指定句柄创建新的 Graphics 对象
Bitmap MemImage = new Bitmap(DesktopBitmapSize.Width, DesktopBitmapSize.Height, Graphic);//生成图像
Graphics MemGraphic = Graphics.FromImage(MemImage);//从指定的 Image 对象创建新 Graphics 对象
IntPtr dc1 = Graphic.GetHdc();//获取与此 Graphics 对象关联的设备上下文的句柄
IntPtr dc2 = MemGraphic.GetHdc(); BitBlt(dc2, 0, 0, DesktopBitmapSize.Width, DesktopBitmapSize.Height, dc1, 0, 0, 0xCC0020);
            MemGraphic.DrawIcon( 这地方怎样写, Cursor.Position.X, Cursor.Position.Y);
              Graphic.ReleaseHdc(dc1);//释放通过以前对此 Graphics 对象的 GetHdc 方法的调用获得的设备上下文句柄
MemGraphic.ReleaseHdc(dc2);
Graphic.Dispose();
MemGraphic.Dispose();
return MemImage;
        }

Answer 1

Cursor.Draw 方法public void Draw (
Graphics g,
Rectangle targetRect
)

Answer 2

那怎样当前光标Cursor　cur呢？
怎样设置？

Answer 3

Rectangle   targetRect 
怎样处理?
没有直接在一点画的吗?
用MemGraphic.DrawIcon(   这地方怎样写,   Cursor.Position.X,   Cursor.Position.Y); 怎样用?

Answer 4

            Bitmap bmp = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
            Graphics gs = Graphics.FromImage(bmp);
            Graphics gs1 = this.CreateGraphics();
            Cursor.Current.Draw(gs, new Rectangle(Cursor.Position.X - Cursor.Current.HotSpot.X, Cursor.Position.Y - Cursor.Current.HotSpot.Y, Cursor.Current.Size.Width, Cursor.Current.Size.Height));
            gs1.DrawImage(bmp, 0, 0);
            gs1.Dispose();
            gs.Dispose();
            bmp.Dispose();

Answer 5

new   Rectangle(Cursor.Position.X   -   Cursor.Current.HotSpot.X,   Cursor.Position.Y   -   Cursor.Current.HotSpot.Y,   Cursor.Current.Size.Width,   Cursor.Current.Size.Height); 
要释放的!怎样释放?
