reading the whole line from a file into a variable

Hi,
I am doing :
Code:
while read line
do
     printf "%s\n" ${line}
done <datafile.txt

but I am not getting each single line from the data file assigned to the variable line (but only tokens/fields at a time). I also tried
Code:
while IFS= read -r line

I want the whole line assigned or read into the variable (and not its tokens/fields at a time) Any suggestions?

Thanks.
