Quote:

JSON

{ "item a", "item b", "item c" }

That is not valid JSON. You will not be able to parse it using any JSON library.

A JSON array would use [ and ]:

JSON

[ "item a", "item b", "item c" ]

Since it's wrapped in { and }, it should be an object literal instead. However, object literals require values for their properties:

JSON

{ "item a": "some value", "item b": 42, "item c": false }

An object literal with property names without values is not valid JSON.

See the JSON specification[^] for more details.

You can't - that isn't valid JSON data.
JSON looks like this:

{
  "contacts": [
    {
      "id": 7113,
      "name": "James Norris",
      "birthDate": "1977-05-13T00:00:00",
      "phone": "488-555-1212",
      "address": {
        "postalCode": "92115",
        "street": "4627 Sunset Ave",
        "city": "San Diego",
        "state": "CA"
      }
    },
    {
      "id": 7114,
      "name": "Mary Lamb",
      "birthDate": "1974-10-21T00:00:00",
      "phone": "337-555-1212",
      "address": {
        "postalCode": "49245",
        "street": "1111 Industrial Way",
        "city": "Dallas",
        "state": "TX"
      }
    },
    {
      "id": 7115,
      "name": "Robert Shoemaker",
      "birthDate": "1968-02-08T00:00:00",
      "phone": "643-555-1212",
      "address": null
    }
  ]
}

And your's isn't - it's just a collection of strings.
A list would look more like this:

{MyItems:[{item:"item a"},{item: "item b"},{item:"item c"}]}

And give C# classes like this:

C#

public class MyItem
{
    public string item { get; set; }
}

public class Root
{
    public List<MyItem> MyItems { get; set; }
}
