Dynamically drawing the taskbar icon implementation of C #

Usually we encounter the need to do an application: To display the number of received message bars to the taskbar, such as the following effect

How to achieve it?

The code is as follows:

<summary>
///dynamically set the taskbar icon
</summary>
<param name= "Number" ></param>
  Public voidSettaskicondynamic (stringNumber ) {          //dynamically draw icon StylesSize size = This.     Icon.size; Bitmap Cursorbitmap=NewBitmap (size. Width, size.     Height); Graphics Graphics=graphics.fromimage (CURSORBITMAP); Graphics. Clear (Color.FromArgb (0,0,0,0)); Graphics.     Resetclip (); Rectangle rect=NewRectangle (0,0, size. Width, size. Height);

//gdi+ Custom draw icon       graphics. DrawImage ( This.     Icon.tobitmap (), rect); Graphics. FillEllipse (NewSolidBrush (Color.FromArgb (244,107,Ten)),NewRectangle (rect. Width/2-2, Rect. Height/2-2, Rect. Width/2, Rect. Height/2)); Graphics. DrawString (number, This. Font, Brushes.white,NewRectangle (rect. Width/2-2, Rect. Height/2-2, Rect. Width/2, Rect. Height/2),NewStringFormat () {linealignment=Stringalignment.center, Alignment=stringalignment.center}); //Generate iconIcon cursor =Icon.fromhandle (Cursorbitmap.gethicon ()); Graphics.      Dispose ();      Cursorbitmap.dispose (); //update taskbar icon style       This. Icon =cursor;}

Take it, no thanks!
