How to set name to the JObject by c#?

Question

I get the json from server, add JObject to the JArray. I want to set a name to that json. I do not know how to do it.

foreach(var i = 0; i < 2; i++)
{
  var array = new JArray();
  var jsonFromServer = GetDataFromServer();
  var strAsJson = JsonConvert.DeserializeObject<JObject>(jsonFromServer);
  array.Add(strAsJson);
}

I am having now:

[
{...},
{...},
{...}
]

My task is:

[
"0": {...},
"1": {...},
"2": {...}
]

I can not to set the name to the JObject. I can to add the name to the JProperty, but I can not to add JProperty to JArray, because it is not a JObject. I can use the JObject instead and add the json to JsonProperty, but I have to use the JArray.

The desired JSON you show in your question is invalid. You cannot put properties (key-value pairs) directly inside an array in JSON. They must be inside objects. See json.org. You could do [ { "0": { ... }}, { "1": {...}}, { "2": {...}} ] though. — Brian Rogers

Try this method:

var obj = new JObject();
obj.Add($"{i}", strAsJson);

array.Add(obj);

Or this handy one-liner:

array.Add(new JObject(new JProperty($"{i}", JsonConvert.DeserializeObject(jsonFromServer))));
