[c#] How to get some values from a JSON string in C#?

I have a string and I want to get some values from it.

My strings seem like:

string1:

"{\r\n   \"id\": \"100000280905615\",
 \r\n \"name\": \"Jerard Jones\",
 \r\n   \"first_name\": \"Jerard\",
 \r\n   \"last_name\": \"Jones\",
 \r\n   \"link\": \"https://www.facebook.com/Jerard.Jones\",
 \r\n   \"username\": \"Jerard.Jones\",
 \r\n   \"gender\": \"female\",
 \r\n   \"locale\": \"en_US\"\r\n}"

string2:

"{\r\n   \"id\": \"100000390001929\",
  \r\n   \"name\": \"\\u05d1\\u05d2\\u05e8\\u15dc\\u25d9 \\u05d1\\u05e8\\u05d5\\u05e9\",
  \r\n   \"first_name\": \"\\u05d4\\u05d2\\u05e7\\u02dc\\u05d9\",
  \r\n   \"last_name\": \"\\u05d1\\u05e8\\u05d5\\u05e9\",
  \r\n   \"link\": "https://www.facebook.com/people/\\u05d2\\u05d1\\u05e@\\u05dc\\u05d9-\\u05d1\\u05e8\\u05d4\\u05e9/100000390001929\",
  \r\n   \"gender\": \"female\",
  \r\n   \"locale\": \"he_IL\"\r\n}"

Unfortunately, there is a situation that a string will be by the same concept, but without some parameters:

string3:

"{\r\n   \"id\": \"100000390001929\",
  \r\n   \"last_name\": \"\\u05d1\\u05e8\\u05d5\\u05e9\",
  \r\n   \"gender\": \"female\",
  \r\n   \"locale\": \"he_IL\"\r\n}"

How can I get the values of: id, first_name, last_name, gender, locale?

Any help appreciated!

my string

var obj = {"Status":0,"Data":{"guid":"","invitationGuid":"","entityGuid":"387E22AD69-4910-430C-AC16-8044EE4A6B24443545DD"},"Extension":null}

Following code to get guid:

var userObj = JObject.Parse(obj);
var userGuid = Convert.ToString(userObj["Data"]["guid"]);

Following code is working for me.

Usings:

using System.IO;
using System.Net;
using Newtonsoft.Json.Linq;

Code:

 using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
                {
                    using (Stream responseStream = response.GetResponseStream())
                    {
                        using (StreamReader responseReader = new StreamReader(responseStream))
                        {
                            string json = responseReader.ReadToEnd();
                            string data = JObject.Parse(json)["id"].ToString();
                        }
                    }
                }

//json = {"kind": "ALL", "id": "1221455", "longUrl": "NewURL"}

Create a class like this:

public class Data
{
    public string Id {get; set;}
    public string Name {get; set;}
    public string First_Name {get; set;}
    public string Last_Name {get; set;}
    public string Username {get; set;}
    public string Gender {get; set;}
    public string Locale {get; set;}
}

(I'm not 100% sure, but if that doesn't work you'll need use [DataContract] and [DataMember] for DataContractJsonSerializer.)

Then create JSonSerializer:

private static readonly XmlObjectSerializer Serializer = new DataContractJsonSerializer(typeof(Data));

and deserialize object:

// convert string to stream
byte[] byteArray = Encoding.UTF8.GetBytes(contents);
using(var stream = new MemoryStream(byteArray))
{
    (Data)Serializer.ReadObject(stream);
}
