Printing numeric values as HEX

I sometimes need to print integer numeric values as a hexadecimal string for better reading and everytime I have to search about it with google.

So here is a collection of printing values as hexadecimal string.

The simpliest way is to use the IFormattable interface:

   1:  String.Format("{0:X02}", int.MaxValue);

Other ways with support of differend radix is to user Convert.ToString().
Radix could be 2, 8, 10, or 16.

   1:  Convert.ToString(int.MaxValue, 2);

From:
MSDN: Convert.ToString()
mikrocontroller.net

Are there any other ways? So let me know!
