Use Case:

We have this Object and you want to convert it into JSON.
Sounds simple. Right !!

However, the trick here is that you need to add couple of fields dynamically to the object, before converting.

Solution

Run the below code in Linqpad (https://www.linqpad.net/), to see it working.

Make sure you press F4, and add the Nuget package i.e. Newtonsoft.Json

I have created this extension method AddFieldsAndConvertToJson. We are simply passing array of tuple's with the required field name & data to the extension.

Check the output below. The fields are getting added to the employee object dynamically, and the JSON is being outputted.

There might be a specific situation, where this extension might come in handy.

Hope you find it useful.

Happy Coding !!
