Get value from JSON object in c#

Question

I am getting JSON response from a url and I am capturing it with following code in jObj2

dynamic jObj2 = JsonConvert.DeserializeObject(resultCheck.Content.ReadAsStringAsync().Result);
Response.Write("<p>"+jObj2+"<p>");

Output is:

{
    "method":"check",
    "trace":"1234/12345/123456f5",
    "order":{
        "ref":"2910730E3E90D40F59BC9B738E71EF7AD9DF679C93D34EAEADA6775216F12C13",
        "cartid":"1723873570174343",

        },

            "last4":"0002",
            "expiry":{
                "month":3,
                "year":2017
            }
        },
        "customer":{
            "email":"email@email.com",
            "name":{
                "forenames":"James",
                "surname":"Senior"
            },
            "address":{
                "line1":"Denvour",
                "city":"Denvour",

This might help to get the desired output

JToken token = JObject.Parse(JsonConvert.DeserializeObject(resultCheck.Content.ReadAsStringAsync().Result));
Response.Write("<br> token.SelectToken("description") " + token.SelectToken("description"))

How can i address `code` which is in two places `status>code` | `transaction>code` – Learning Feb 07 '17 at 08:29
I would suggest you to use [`Json.Net`](http://stackoverflow.com/a/40416621/3796048) for getting the values from this JSON Structure. – Mohit S Feb 07 '17 at 08:31
Am i not using json.net `using Newtonsoft.Json;` – Learning Feb 07 '17 at 08:39
