When writing a help document, the intercepted pictureif there is a mouse pointer shape, it will look more intuitive and friendly. Next, let’s talk about how to include the mouse pointer shape in the screenshot.

Add structure CURSORINFO:

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

Declare API:

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

Define enumeration value:

private const int CURSOR_SHOWING = 0x00000001;

Add method:

        /// <summary>
        /// 将鼠标指针形状绘制到屏幕截图上
        /// </summary>
        /// <param name="g"></param>
        private void DrawCursorImageToScreenImage(ref Graphics g)
        {
            if (!this.IsCutCursor) { return; }

            CURSORINFO vCurosrInfo;
            vCurosrInfo.cbSize = Marshal.SizeOf(typeof(CURSORINFO));
            GetCursorInfo(out vCurosrInfo);
            if ((vCurosrInfo.flags & CURSOR_SHOWING) != CURSOR_SHOWING) return;
            Cursor vCursor = new Cursor(vCurosrInfo.hCursor);
            Rectangle vRectangle = new Rectangle(new Point(vCurosrInfo.ptScreenPos.X - vCursor.HotSpot.X, 
            vCurosrInfo.ptScreenPos.Y - vCursor.HotSpot.Y), vCursor.Size);

            vCursor.Draw(g, vRectangle);
        }

Add method call:

OK, let’s take a screenshot again!
