Also, when posting a LINQ query, it is still sometimes a good idea to mention that it only works >3.5 unless the questions specifically mentions version. No better answer given the constraints though. – Nick Larsen Mar 16 '10 at 13:24

With LINQ (that's all the rage these days):

int RowFormat = drr[3].Count(x => x == '#');

Check this

"grtkj####mfr".Split(new char[]{'#'}).Length-1

hope that will help.
