Its been a while since Ive had to write what amounts to a custom format edi processor. The last time I wrote one, I was an AS/400 programmer (not iSeries to give you a timeframe). It was pretty easy, I built a structure and inspected the record type column and began processing based on the fix positions of data and record type.
Fast forward to 2012 and I have almost exactly the same requirements except I no longer have an AS/400 to make it easy.
For brevity, the first 2 columns contain a record type and the structure is based on that type. Any suggestion on how to best handle this in c# on a web server?
Some options I have considered are filehelpers and SSIS. I have full control over the environment so I can do pretty much anything that makes sense.
