在寫一此協助說明類的文檔時,截取的圖片如果還有滑鼠的指標形狀,看起來就更直觀更友好一些。接下來就講一下如何在中包含滑鼠指標形狀。

添加結構CURSORINFO:

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

聲明API:

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

定義枚舉值:

private const int CURSOR_SHOWING = 0x00000001;

添加方法:

        /// <summary>        /// 將滑鼠指標形狀繪製到螢幕上        /// </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);        }

添加方法調用:

OK,再去看看吧!
