JSONGenerator object

The JSONGenerator object provides the ability to construct the JSON
objects with the root item being either an object or an array. It supports
adding values, objects, or arrays to the constructed JSON object.

Note

It is not recommended to use this object to process large data (20
MB or 100,000 data rows can be considered as large data based on our
tests), because this object will call a third-party library which is
memory intensive.

Note

This object cannot be referenced in .NET Web Service or .NET
Assembly components, otherwise the component will fail to be
deployed.
