I'm curious as to why you have all those separate arrays in the first place if you actually do have a Jobs class that represents a single job. By the way, if it represents a single job then it should be named Job, not Jobs.

Regardless, I would tend to replace this:
vb.net Code:
  1. OutputLine = HelpDesk(JobC) + "," + TypeA(JobC) + "," + Specialist(JobC) + "," + Comments(JobC) + "," + Summary(JobC) + "," + Description(JobC)
  2. iWrite.WriteLine(OutputLine)
with this:
vb.net Code:
  1. iWrite.WriteLine(String.Join(",", HelpDesk(JobC), TypeA(JobC), Specialist(JobC), Comments(JobC), Summary(JobC), Description(JobC)))
