how can i get the json intent data in to c#?

Question

Below is my class for the json output:

class PwdResetRequest
{
public class TopScoringIntent
{
public string intent { get; set; }
public double score { get; set; }
}
public class Intent
{
public string intent { get; set; }
public double score { get; set; }
}
public class Resolution
{
public string value { get; set; }
}
public class Entity
{
public string entity { get; set; }
public string type { get; set; }
public int startIndex { get; set; }
public int endIndex { get; set; }
public Resolution resolution { get; set; }
}
public class RootObject
{
public string query { get; set; }
public TopScoringIntent topScoringIntent { get; set; }
public List<Intent> intents { get; set; }
public List<Entity> entities { get; set; }
}
}

Luis Return result:

{ "query": "create a new password for [email protected]", "topScoringIntent": { "intent": "ResetLANIDpassword", "score": 0.9956063 }, "intents": [ { "intent": "ResetLANIDpassword", "score": 0.9956063 }, { "intent": "None", "score": 0.179328963 } ], "entities": [ { "entity": "[email protected]", "type": "builtin.email", "startIndex": 26, "endIndex": 47 } ] }

I have developed the below code for getting the data from the json.

var uri = "https://westus.api.cognitive.microsoft.com/luis/v2.0/apps/" + luisAppId + "?" + queryString;
var response = await client.GetAsync(uri);
var strResponseContent = await response.Content.ReadAsStringAsync();
var json = await response.Content.ReadAsStringAsync();
var token = JObject.Parse(json).SelectToken("entities");
foreach (var item in token)
{
var request = item.ToObject<Entity>();
}
// Display the JSON result from LUIS
Console.WriteLine(strResponseContent.ToString());
}

And I only want the data from the "TopScoringIntent". How can I get that using C#? Below is the code that I tried but nothing came out: Message=Error reading JObject from JsonReader. Path '', line 0, position 0. Source=Newtonsoft.Json
