如何使用Windows API捕获屏幕和鼠标指针？

Posted 2021-05-04

我正在使用以下代码捕获位图中的屏幕。屏幕被捕获，但我无法在屏幕上显示鼠标指针。您能否建议一些替代方法，以便捕获鼠标？

    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;
        }
    }
