I am looking to create a JSON array from a CSV or Database. How would I format my source data or does anyone have advice/links to tutorials for either creating a .NET Web Service or another method to generate JSON from a CSV or database? An example array is below.

Example:

{
section1: [
{
"id":1,
"title":mytitle1
}
],
{
section2: [
{
"id":2,
"title":mytitle2
}
], etc.....

I would first convert my csv file to an object, then parse the object to JSON using newtonsoft's json class

Check this out to learn how to transform CSV to object

Go here to get newtonsoft's json.net tools (can be done using nuget)
