How to convert a JSON array to an array of string values

Question

I'm try to parse some JSON like this:

{
   "results": [
       "MLU413843206",
       "MLU413841098",
       "MLU413806325",
       "MLU413850890",
       "MLU413792303",
       "MLU413843455",
       "MLU413909270",
       "MLU413921617",
       "MLU413921983",
       "MLU413924015",
       "MLU413924085"
   ]
}

All is fine until I try to obtain the values themselves, for example:

 // The JSON is shown above
 var jsonResp = JObject.Parse(json);    
 var items = jsonResp["results"].Children();

I don't know how to obtain the values, each converted to string. Does somebody know how to do this?

The JSON you're trying to parse is not valid. Between the key and the value there should not be a minus symbol. — user3038092

you should learn json structure first. Means how one json object structure is — Chandan Kumar

What I need is obtain the text inside this JSON using JSON.NET , I have obtained this using another techniques with string parsing, etc. But I don't want do it in this way. I want a elegant way using JSON.NET in this case. — Vkt0r

You're halfway there. You can use the Select() method in the System.Linq namespace to project the IEnumerable<JToken> returned from the Children() method into an IEnumerable<string>. From there you can loop over the values using foreach, or put the values into a List<string> using ToList() (or both).

string json = @"
{
    ""results"": [
        ""MLU413843206"",
        ""MLU413841098"",
        ""MLU413806325"",
        ""MLU413850890"",
        ""MLU413792303"",
        ""MLU413843455"",
        ""MLU413909270"",
        ""MLU413921617"",
        ""MLU413921983"",
        ""MLU413924015"",
        ""MLU413924085""
    ]
}";

JObject jsonResp = JObject.Parse(json);
List<string> items = jsonResp["results"].Children()
                                        .Select(t => t.ToString())
                                        .ToList();
foreach (string item in items)
{
    Console.WriteLine(item);
}
