as strong suggestion: don't try invent own csv writer / reader. seems easy, there dragons in water, lots of dragons. escaping strings fun - how manage line

escaping thin takes lot of work.

so go ahead , use library like: http://kbcsv.codeplex.com/ it's free, fast , saves days of work.

as further questions: sheet 2 excel file?
