C#

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 sjao9841@demo.com",
  "topScoringIntent": {
    "intent": "ResetLANIDpassword",
    "score": 0.9956063
  },
  "intents": [
    {
      "intent": "ResetLANIDpassword",
      "score": 0.9956063
    },
    {
      "intent": "None",
      "score": 0.179328963
    }
  ],
  "entities": [
    {
      "entity": "sjao9841@demo.com",
      "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
