JSON.NET JObject key comparison case-insensitive

Question

I'm using Newtonsoft Json.net to parse the JSON string. I convert the string into the JObject. When access the value of the element by the key, I want to the comparison is case-insensitive. In the code below, I use "FROM" as the key. I want it returns string "1" at the line json["FROM"].ToString(). But it fails. Is it possible to make the code below work?

String ptString = "{from: 1, to: 3}"; var json = (JObject)JsonConvert.DeserializeObject(ptString);  String f = json["FROM"].ToString(); 

Answer 1

This should work:

var json = @"{UPPER: 'value'}"; var jObj = JObject.Parse(json); var upper = jObj.GetValue("upper", StringComparison.OrdinalIgnoreCase)?.Value<string>();  Console.WriteLine(upper); // value
