Solution 1

Create a new image of the appropriate size.
Get the Graphics object for the image (using Graphics.FromImage)
Draw the number on the image (using Graphics.DrawString) in the appropriate font and size.
Dispose the graphics object.
Use the image as required.

Solution 2

Bitmap bmp = new Bitmap(16, 16);
using (Graphics g = Graphics.FromImage(bmp)) // Bmp with clear background of given color
Font drawFont = new Font("Arial", 16);
SolidBrush drawBrush = new SolidBrush(Color.Black);
string theNumber="8";
g.DrawString(theNumber,drawFont,drawBrush,new Point(100,100))
notifyIcon1.Icon = Icon.FromHandle(bmp.GetHicon());

Good enough, for illustration, my 4.
In real life those immediate constants should not be hard-coded there (it's more of OP).
Instead of new SolidBrush(Color.Black) better be Brushes.Black.
There is no calls to Dispose (see Griff's Answer).
Dispose should not be called directly but via "using" construct, the ensure calling Dispose on exception.
Did I voted "4" with all that notes? OK, fine... :-)
