Determine Data File Structure(repost)

I have a competitor's software that I would like to import data from. They use a text file to store data, each line containing a different field. But here's where it gets tricky. They use a variant field order based on four lines of numbers at the beginning of the file. I can provide the software and sample data files. I need someone to help me develop an algorithym in C# to read these data files in. The competitor's software is in the zip file. Update: I need to simply be able to read in the data file to my variables and such. Each file is essentially one record, and the key is determining the order of the fields within each file, as the order varies from file to file and is determined by some kind of algorithym, which is what I need figured out. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Documentation of file structure. ## Platform C#, Windows
