(C# UWP/WinRT) Modify Parts of JSON Document

Demonstrates how to modify parts of a JSON document. This example uses the following JSON document:

{
   "fruit": [
      	{
         "kind": "apple",
	 "count": 24,
	 "fresh": true,
	 "extraInfo": null,
	 "listA": [ "abc", 1, null, false ],
	 "objectB": { "animal" : "monkey" }
      	},
	{
         "kind": "pear",
	 "count": 18,
	 "fresh": false,
	 "extraInfo": null
	 "listA": [ "xyz", 24, null, true ],
	 "objectB": { "animal" : "lemur" }
	}
    ],
    "list" : [ "banana", 12, true, null, "orange", 12.5, { "ticker": "AAPL" }, [ 1, 2, 3, 4, 5 ] ],
    "alien" : true
}

Chilkat.JsonObject json = new Chilkat.JsonObject();

// Load the JSON from a file.
bool success = json.LoadFile("qa_data/json/modifySample.json");
if (success != true) {
    Debug.WriteLine(json.LastErrorText);
    return;
}

// This example will not check for errors (i.e. null / false / 0 return values)...

// Get the "list" array:
Chilkat.JsonArray listA = json.ArrayOf("list");

// Modify values in the list.

// Change banana to plantain
success = listA.SetStringAt(0,"plantain");

// Change 12 to 24
success = listA.SetIntAt(1,24);

// Change true to false
success = listA.SetBoolAt(2,false);

// Is the 3rd item null?
bool bNull = listA.IsNullAt(3);

// Change "orange" to 32.
success = listA.SetIntAt(4,32);

// Change 12.5 to 31.2
success = listA.SetNumberAt(5,"31.2");

// Replace the { "ticker" : "AAPL" } object with { "ticker" : "GOOG" }
// Do this by deleting, then inserting a new object at the same location.
success = listA.DeleteAt(6);
success = listA.AddObjectAt(6);
Chilkat.JsonObject tickerObj = listA.ObjectAt(6);

// Get the "fruit" array
Chilkat.JsonArray aFruit = json.ArrayAt(0);

// Get the 1st element:
Chilkat.JsonObject appleObj = aFruit.ObjectAt(0);

// Modify values by member name:

success = appleObj.SetIntOf("count",46);
success = appleObj.SetBoolOf("fresh",false);
success = appleObj.SetStringOf("extraInfo","developed by growers at the Tohoku Research Station in Fujisaki");

// Modify values by index:

success = pearObj.SetIntAt(1,12);
success = pearObj.SetBoolAt(2,false);
