Device Info JSON Deserializing

Question

I've read a number of questions about this subject on here but never understood how to sort the problem.

When setting up the classes from JSON output with JSON2CSharp i get the following output as I have number values for each name with the public class __invalid_type__1 and __invalid_type__2, how do i over come this? I've looked at using Dictionary but don't understand fully how to implement this as I'm new to coding and c#, or is there a better way to do this?

[DataContract]
public class State
{
    [DataMember]
    public bool on { get; set; }
    [DataMember]
    public int bri { get; set; }
}

[DataContract]
public class __invalid_type__1
{
    [DataMember]
    public State state { get; set; }
    [DataMember]
    public string type { get; set; }
    [DataMember]
    public string name { get; set; }
    [DataMember]
}

[DataContract]
public class State2
{
    [DataMember]
    public bool on { get; set; }
    [DataMember]
    public int bri { get; set; }
}

[DataContract]
public class __invalid_type__2
{
    [DataMember]
    public State2 state { get; set; }
    [DataMember]
    public string type { get; set; }
    [DataMember]
    public string name { get; set; }
}

[DataContract]
public class RootObject
{
    [DataMember]
    public __invalid_type__1 __invalid_name__1 { get; set; }
    [DataMember]
    public __invalid_type__2 __invalid_name__2 { get; set; }
}

my code for deserialzing Json is

 public async static Task<RootObject> GetL ()
    {
        var http = new HttpClient();
        var url = String.Format("http://192.168.0.71/api/apikey/");
        var response = await http.GetAsync(url);
        var result = await response.Content.ReadAsStringAsync();
        var serializer = new DataContractJsonSerializer(typeof(RootObject));

        var ms = new MemoryStream(Encoding.UTF8.GetBytes(result));
        var data = (RootObject)serializer.ReadObject(ms);

        return data;
     }
