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

Durga Prasad Karrothu

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 intents { get; set; }
public List 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();
}
// 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

You can do like this...
static void Main(string[] args)
{
    string json = "{ \"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 } ] }";

    var entities = JObject.Parse(json).SelectToken("entities");
    foreach (var item in entities)
    {
        PwdResetRequest.Entity entitiesObj = item.ToObject();
    }

    var topScoringIntent = JObject.Parse(json).SelectToken("topScoringIntent");
    PwdResetRequest.TopScoringIntent topScoringIntentObj = topScoringIntent.ToObject();
    Console.ReadKey();
}

Hello Durga Prasad,

I have done something similar what you are trying to achieve. Below code snippet will return the sentiment score of text you entered. I hope it will help

static async void MakeRequest()
{
var client = new HttpClient();
var queryString = "";
// Request headers
client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", "YOUR KEY IN HERE");
var json = "{ \"documents\": [ { \"language\": \"en\", \"id\": \"1\", \"text\": \"I had a wonderful experience\" }, { \"language\": \"en\", \"id\": \"2\", \"text\": \"It was an Ugly picture\" } ]}";
var uri = "https://westus.api.cognitive.microsoft.com/text/analytics/v2.0/sentiment?" + queryString;
HttpResponseMessage response;
// Request body
byte[] byteData = Encoding.UTF8.GetBytes(json);
using (var content = new ByteArrayContent(byteData))
{
content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
response = await client.PostAsync(uri, content);
Console.WriteLine(response.Content.ReadAsStringAsync().Result);
}
}

Thanks everyone i am able to get the data from the json object

Are you getting proper json data as response???

static async void MakeRequest()
{
var client = new HttpClient();
var queryString = HttpUtility.ParseQueryString(string.Empty);
// This app ID is for a public sample app that recognizes requests to turn on and turn off lights
var luisAppId = "52fa9d5f-7cc1-41c4-a66b-6620216eefb0";
var subscriptionKey = "35d2ee08f36744c6a02c0ce42693fcc9";
// The request header contains your subscription key
client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", subscriptionKey);
// The "q" parameter contains the utterance to send to LUIS
queryString["q"] = "create a new password for [email protected]";
// These optional request parameters are set to their default values
queryString["timezoneOffset"] = "0";
queryString["verbose"] = "false";
queryString["spellCheck"] = "false";
queryString["staging"] = "false";
var uri = "https://westus.api.cognitive.microsoft.com/luis/v2.0/apps/" + luisAppId + "?" + queryString;
//******disable this and lets assuming I have json response********//
var json = "{ \"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 } ] }";
//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");
var entities = JObject.Parse(json).SelectToken("entities");
foreach (var item in entities)
{
Entity entitiesObj = item.ToObject();
}
// Display the JSON result from LUIS
}
