Due to an odd conjunction of stars (trust me, thats a better reason than the real one), I need to store text data in a SQLServer Image column

I'm looking for a cleaner method to convert strings to byte[] and vice versa. So far the only implementation I have been able to make work has been to do an iteration of the array and convert one character at a time in either direction

I've looked into Streams and Textwriters but none of them seem to be quite what I need. Can anyone suggest a cleaner method of doing a conversion than the rather clunky
for(int i=0; i< myChars.Length; i++) { myBytes[i] = Convert.ToByte(myChars[i]);

?

That's not just clunky - it's broken. As soon as you've got a character
with a Unicode value greater than 255, you'll get an exception.

Fortunately, the Encoding class is provided to do exactly what you
want. Just select the encoding you want and call GetBytes.
