json.net IEnumerable

c#, c#-3.0, json.net

Solution

Or you can do this:

 string json = "{\"fields\":[{\"status\":\"active\",\"external_id\":\"title\",\"config\":{},\"field_id\":11848871,\"label\":\"Title\",\"values\":[{\"value\":\"Test Deliverable\"}],\"type\":\"text\"},{\"status\":\"active\",\"external_id\":\"client-name\",\"config\":{},\"field_id\":12144855,\"label\":\"Client Name\",\"values\":[{\"value\":\"Chcuk Norris\"}],\"type\":\"text\"}]}";

 JObject obj = JObject.Parse(json);

 JArray arr = (JArray)obj["fields"];

 var externalIds = arr.Children().Select(m=>m["external_id"].Value<string>());

externalIds is a IEnumerable array of string

Or you can chain it together and select the object in one line:

var myVal = JObject.Parse(json)["fields"].Children()
                                        .Where(w => w["external_id"].ToString() == "title")
                                        .First();

From there you can append whatever selector you want ie if you want the external_id value then append ["external_id"].ToString() to the end of the first() selector.

Problem

I have the following json file ``` {"fields":[ { "status":"active", "external_id":"title", "config":{}, "field_id":11848871, "label":"Title", "values":[ { "value":"Test Deliverable" } ], "type":"text" },{ "status":"active", "external_id":"client-name", "config":{}, "field_id":12144855, "label":"Client Name", "values":[ { "value":"Chcuk Norris" } ], "type":"text" }} ``` And I want to select the value of the field that has its external_id = "title" for example, I'm using Json.Net and already parsed the object. How do i do this using lambda or linq on the Json object, I trird something like this ``` JObject o = JObject.Parse(json); Title = o["fields"].Select(q => q["extenral_id"].Values[0] == "title"); ``` Which is not event correct in terms of syntax. I'm not very proficient in Lambda or Linq thought its been there for a while. Appreciate the help Thanks Yehia
