This probably has a simple answer, but I must not have had enough coffee to figure it out on my own:
If I had a comma delimited string such as:

Are you going to be processing a lot of CSV? If so, you should also consider using a library to do this. Don't reinvent the wheel. Unfortunately I haven't found a library quite as simple as Python's CSV library, but I have seen FileHelpers (free) reviewed at MSDN Magazine and it looks pretty good. There are probably other free libraries out there as well. It all depends on how much processing you will be doing though. Often it grows and grows until you realize you would be better off using a library.
