How to deserialize this without class object? [duplicate]

Question

I have this restcountries url https://restcountries.eu/rest/v2/all

I want to consume in C#

string URL = "https://restcountries.eu/rest/v2/all";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);
request.ContentType = "application/json; charset=utf-8";
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
using (Stream responseStream = response.GetResponseStream())
{
    StreamReader reader = new StreamReader(responseStream, System.Text.Encoding.UTF8);
    var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();                                                       
    String jsonstr = reader.ReadToEnd();                               
    RootObject obj = serializer.Deserialize<RootObject>(reader.ReadToEnd());
    RootObject robj = serializer.Deserialize<RootObject>(jsonstr);
    //  System.Diagnostics.Debug.WriteLine(reader.ReadToEnd());
    // Console.WriteLine(reader.ReadToEnd());
}

Classes being deserialized:

public class Currency
{
    public string code { get; set; }
    public string name { get; set; }
    public string symbol { get; set; }
}

public class Language

Why have you tagged Json.NET when you're using JavaScriptSerializer? — ProgrammingLlama

Try this!! JavaScriptSerializer json_serializer = new JavaScriptSerializer(); RootObject routes_list = (RootObject )json_serializer.DeserializeObject("{ \"test\":\"some data\"}");

I got this exception sir Unable to cast object of type 'System.Object[]' to type 'NSTestingHelper.Cjsondata.RootObject'.

the Json might in the form of JArray. Make sure your class file matches the json structure using json2c#
