Are you using the comma to separate three digits or two digits?

doubleValue.ToString("#,###.00");

So do you want to put any given number into that format?

I take it that the number is split based on value.

So you should treat the number as a string. work from right to left. search for a "." if the string contains one, that should be treated as the starting point, if not start from the last character.

then ignore the first 3 characters (that is when working from the right). place a "," after the first 3 characters, then a "," after every second character. one for loop and some standard .NET string manipulation commands should do the trick.
