Parsing and validating JSON string in C# [duplicate]

Question

I am working on a side project at work (I'm not a developer).

What I'm trying to achieve is validating whether statusis NULL or it has ERR in the login request response so I can know if I may continue the process.

This is the code I have so far:

namespace EseyeSIMAPI
{
class Program
{
    static void Main(string[] args)
    {
        var client = new RestClient("https://siam.eseye.com/Japi/Tigrillo");
        var loginRequest = new RestRequest("/login/", Method.POST);

        loginRequest.AddHeader("postman-token", "4e67ed4c-4130-4067-9539-d5ed6b6ad761");
        loginRequest.AddHeader("cache-control", "no-cache");
        loginRequest.AddHeader("content-type", "application/json");
        loginRequest.AddParameter("application/json", "{\r\n\"username\" : \"someusername\" ,\r\n\"password\" : \"somepassword\" ,\r\n\"portfolioID\" : \"someportfolioid\"\r\n}", ParameterType.RequestBody);

        IRestResponse response = client.Execute(loginRequest);

        client.ExecuteAsync(loginRequest, x =>
        {
            var json = x.Content;
        });

        Console.ReadLine();
    }
}
public class LoginStatus
{
    public Status status { get; set; }
    public string cookie { get; set; }
    public string permissions { get; set; }
    public string canActivate { get; set; }
}

public class Status
{
    public string errorCode { get; set; }
    public string errorMessage { get; set; }
    public string status { get; set; }
}
}

I receive the following JSON response:

{
"status": {
"errorCode": "",
"errorMessage": "",
"status": "OK"
},
"cookie": "2p255ju6q1lfql594uppnq9lp2",
"permissions": "ULE",
"canActivate": "yes"
}

So I created a class that will handle all the response parameters in the JSON object. I'm just not sure how exactly to access status.

Following on from my comments, this is how you would specifically do it with your code using the JavaScriptSerializer class:

client.ExecuteAsync(loginRequest, x =>
{
    var json = x.Content;

    JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();
    LoginStatus loginStatus = jsonSerializer.Deserialize<LoginStatus>(json);

    string errorCode = loginStatus.status.errorCode;
});
