c# regex to find string containing just one character

Last Modified: 2012-05-09

I need a regular expression to check if a string is made up of just one character.  This is basically to check for lines in a CSV file that have no data in the fields and therefore just contains commas.

This will be incorporated into a generic script, so the actual delimeter, and the number of fields will be abitrary, so I can't just count the number of seperators.  There's probably a simpler way of doing this that i'm over looking.
