I hope this helps you . Just because you have assigned a B to an A does not mean that it is no longer a B. You can see this for yourself if you print out the type of your InstanceA variable after the assignment:
code :
B instanceB = new B() { PropA = "A", PropB = "B" };

A instanceA = instanceB;

Console.WriteLine(instanceA.GetType().Name);
public class BaseTypeConverter<T> : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        return typeof(T).IsAssignableFrom(objectType);
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        T instance = (T)value;
        JObject obj = new JObject();
        foreach (PropertyInfo prop in typeof(T).GetProperties())
        {
            if (prop.CanRead)
            {
                obj.Add(prop.Name, JToken.FromObject(prop.GetValue(instance)));
            }
        }
        obj.WriteTo(writer);
    }

    public override bool CanRead
    {
        get { return false; }
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }
}
B instanceB = new B() { PropA = "A", PropB = "B" };

// serialize B, but only include the properties from type A
string json = JsonConvert.SerializeObject(instanceB, new BaseTypeConverter<A>());

Console.WriteLine(json);
{"PropA":"A"}

may help you . Using Json.Net you can do something like this(it should also work with the JavaScriptSerializer) :
code :
var ReadJson = System.IO.File.ReadAllText(@"E:\C# Learning\POI.json");
RootObject json = JsonConvert.DeserializeObject<RootObject>(ReadJson);
foreach (var item in json.poi)
{
    Console.WriteLine("name: {0}, shorttext : {1}, Latitutde: {2} , Latitutde: {3}, Image: {4}", item.Name, item.Shorttext, item.GeoCoordinates.Latitude, item.GeoCoordinates.Longitude, string.Join(" ", item.Images));
}

With these it helps You need to JArray results = JArray.Parse(token2["d"].ToString());
Please try
code :
WebClient wc = new WebClient();
// Downloading & Deserializing the Json file
var jsonMain = wc.DownloadString("http://api.flexianalysis.com/services/FlexiAnalysisService.svc/FlexiAnalysisNews?key=gZ_lhbJ_46ThmvEki2lF&catagory=Forex");


JObject token2 = JObject.Parse(jsonMain);
JArray results = JArray.Parse(token2["d"].ToString());

List<News> listNews = new List<News>();
foreach (var result in results)
{
    news = new News();
    news.id = (string)result["ID"];
    news.Title = (string)result["Title"];
    news.Date = (string)result["PublishingDate"];
    news.Content = (string)result["News"];
    listNews.Add(news);
}

return View(listNews);

it helps some times Here you go. It works perfect. First download "newtonsoft.json" from Nuget and add it to your project. Struct myStruct is your deserialized json object converted to a struct.
code :
public void DeserializeMyJsonObject()
{
    string json;
    using (StreamReader r = new StreamReader("d:\\json.txt"))
    {
        json = r.ReadToEnd();
    }

    var myStruct = JsonConvert.DeserializeObject<YourStruct>(json);

}

public struct YourStruct
{
    [JsonProperty("params")]
    public List<Object> KeyAndProperties { get; set; }
}

Hope this helps You can use Newtonsoft JSON.
First, add JsonProperty attributes to your classes:
code :
public class ClassA
{
  [JsonProperty("name")]
  public string Name { get; set; }

  [JsonProperty("objects")]
  public ClassB[] Objects { get; set; }
}
public class ClassBConverter : JsonConverter<ClassB> {
    ...

    public override void WriteJson(JsonWriter writer, ClassB value, JsonSerializer serializer)
    {
        writer.WriteValue((int)value.SomeEnum);
    }

    public override ClassB ReadJson(JsonReader reader, Type objectType, ClassB existingValue, bool hasExistingValue, JsonSerializer serializer)
    {
        int i = (int)((long) reader.Value);
        return new ClassB { SomeEnum = i };
    }
}
JsonConvert.(De)SerializeObject<ClassA>(yourJSONString, new ClassBConverter());
