Calculating no. of columns in a flat file

Hi,

I want to find out the no. of columns in a flat file. If it is "," delimited, I am using
awk -F\\, '{print NF;exit}' filename.txt
which is giving me correct results.

But the delimiter can be either comma or pipe delimited. How can I make that provision in Unix?
