Getting the query result of LUIS

I have created a LUIS account and did everything that was needed.

I have written the following code and got the result from LUIS.

I need to know how to save the result of my query to a variable, using which I would like to search the database or web.

Below is the code..

static async void MakeRequest(string qz) {

            var client = new HttpClient();
            var queryString = HttpUtility.ParseQueryString(string.Empty);
            var luisAppId = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
            var endpointKey = "XXXXXXXXXXXX";

            client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", endpointKey);

            // The "q" parameter contains the utterance to send to LUIS
            queryString["q"] = qz;

            // These optional request parameters are set to their default values
            queryString["timezoneOffset"] = "0";
            queryString["verbose"] = "false";
            queryString["spellCheck"] = "false";
            queryString["staging"] = "false";

            var endpointUri = "https://westus.api.cognitive.microsoft.com/luis/v2.0/apps/" + luisAppId + "?" + queryString;
            var response = await client.GetAsync(endpointUri.);

            var strResponseContent = await response.Content.ReadAsStringAsync();


            // Display the JSON result from LUIS
            Console.WriteLine(strResponseContent.ToString());



        }

And also here is the query result.

{
  "query": "the best resturant in Paris",
  "topScoringIntent": {
    "intent": "city",
    "score": 0.436210483
  },
  "entities": [
    {
      "entity": "paris",
      "type": "city",
      "startIndex": 22,
      "endIndex": 26,
      "score": 0.7153605
    }
  ]
}

Now I want to save this 

"entity": "paris",
"type": "city",

to a variable. Kindly guide me as I am completely new to MS LUIS.

example:

string result = "paris" /// which the value should be taken from luis query

string type = "city" /// which the value should be taken from luis query

One option is to reference Newtonsoft.Json NuGet package to your project.

Then you may create two classes (feel free to change the name)

public class LuisExtractionLuisResult
{
    public List<LuisEntity> entities { get; set; }
}

public class LuisEntity
{
    public string entity { get; set; }

    public string type { get; set; }
}

Then one example of use is

var target = JsonConvert.DeserializeObject<LuisExtractionLuisResult>(strResponseContent);

requested values are then retrieved by:

string result = target.entities[0].entity;
string type = target.entities[0].type;

And one more question, if in the query we have more than one entities. how to get that as well?

foreach(LuisEntity oneEntity in target.entities)
{
    string result oneEntity.entity;
    string type = oneEntity.type;
}
