i need to sort an string Array and it MUST be sorted by ascii.

if using Array.Sort(myArray), it won't work.

for example:
myArray is ("aAzxxxx","aabxxxx")
if using Array.Sort(myArray)
the result will be 

1. aabxxxx
2. aAzxxxx

but if ascii sort, because A < a, (capital A is 65, a is 97, so A < a)
the result will be 

1. aAzxxxx
2. aabxxxx

this is the result i need. any ideas about how to ASCII sort an string Array?

thx
