Easier way to serialize int value using JSONUtility ?

Hi, im looking for the easiest way to serialize a primitive value - in this case - a variable holding an int value.

According to JSON Serialization doc, the "easiest" way to do that is create a class/struct ... wait what? For simple int variable? So i tried this and it works:

 using System;
 
 [Serializable]
 public struct SerializableInt
 {
     public int value;
 }

and then elsewhere:

 SerializableInt myInt = new SerializableInt();
 myInt.value = 1;
 Debug.Log (JsonUtility.ToJson(myInt)); // {"value":1}

but this looks as verbose as ever. Is there easier way to JSONize / StringIFY that?

Alternate approach not using JSON maybe?

My requirement is to pass string and parse it based on "dataType" something like:

 switch (dataType) {
     case "int": // parse as if string contained ints only - using SerializableInt here currently
     case "float": // parse as if string contained float - SerializableFloat ???
     case "Array": // parse as if string contained array - SerializableArray ???
     case "Vector3": // fortunately we CAN parse the string using JSON directly.
     etc
 }
