C # Development Example-Custom screenshot tool (10) Include the mouse pointer shape in the screenshot

When you write a document that helps explain the class, the captured picture is more intuitive and more user-friendly if it has a pointer to the mouse shape. Now let's talk about how to include the mouse pointer shape in.

Add Structure Cursorinfo:

[StructLayout (layoutkind.sequential)]        struct Cursorinfo        {public            int cbsize;            public int flags;            Public IntPtr hcursor;            Public point Ptscreenpos;        }

Declaration API:

        [DllImport ("User32.dll")]        static extern bool Getcursorinfo (out Cursorinfo PCI);

To define an enumeration value:

Private Const int cursor_showing = 0x00000001;

To add a method:

        <summary>////Draw the mouse pointer to the screen////</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);        }
