Revisited---String to Decimal to Binary Converter
In a previous post, I posted a piece of code that would convert a string to its decimal equivalent and then its binary equivalent. For example:
Mathew is returned back as 01001101 01100001 01110100 01101000 01100101 01110111
A very good comment pointed out that i can just use Convert.ToString() method. I have used this class extensively but I never noticed the versions that converts either a byte, int16 or int32 to different numeric bases (e.g. base 2). I will cut myself a bit of slack because there are 36 different overridden versions of Convert.ToString(), but its a nice feature and well worth pointing out. Furthermore, it reduces the size of my code considerably(see below). Also, I could probably have made the code a bit more generic, but at the end of the day the class is still pretty useless (I just wanted to come up with a way to create clever IM display names)...so why bother ;-)
