I recommand you use Newtonsoft Json lib, available as a nuget package.

You can the make a model class to represent on of the json node then you can de-serialize you Json to that model and build an array containing the new element at the end to then re-serialize it to json after.

Look at this MSDN page about it: https://msdn.microsoft.com/en-us/library/bb412179(v=vs.110).aspx

Edit: Actual NewtonSoft Documentation

In steps: 1 Deserialize the collection

2: And a new class instance with listName.Add(className);

3: Reserialize the collection
