Answer 1

The problem here is that each row in the DataTable is a simple set of name/value pairs, but you want each person's EducationInfo as another layer in the result JSON. Furthermore you want multiple rows to become a single JSON object if all fields but EducationInfo match.

There isn't going to be a simple "Go()" method that will do this for you out of the box.

I suggest creating Student and EducationInfo classes to hold the information, and aggregate the data yourself into a Student[] array.

Then you simply serialize them using your favorite serializer. As a side effect, this makes debugging so much easier.
