Microsoft Cognitive Services Web Search API - DeSerialization Issues - botframework

Question

I want to learn Cognitive Services Web Search APIs so I started creating a bot application . I already have a account sub- key and other required information also I read many articles and watch build 2016 videos on this as well.I am having trouble while deserializing the result .
I am not able to find the proxy class that I can use to do that .
The url I am using is https://api.cognitive.microsoft.com/bing/v5.0/search/
and I found a proxy class for previous api version . Can anybody tell me how to get proxy class of the api request / response in VS 2015 for these service.
My Code look like this:
string BingSearchUrl = "https://api.cognitive.microsoft.com/bing/v5.0/search/";
const string bingKey = "Key";
public static async Task<string> Search(string query)
{
var client = HttpClientFactory.Create();
var queryString = BingSearchUrl + "?q=" + query + "&count=10";
// Request headers
client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", bingKey);
client.DefaultRequestHeaders.Add("Accept", "application/json");
// Request parameters
string r = await client.GetStringAsync(queryString);
var jsonResult = JsonConvert.DeserializeObject<Bing.ExpandableSearchResult>(r);
return jsonResult.Web.First().Title;

Answer 1

Try below code
public string BingSearchUrl = "https://api.cognitive.microsoft.com/bing/v5.0/search/";
const string bingKey =[KEY];
public async void Search()
{
var client = new HttpClient();
var queryString = HttpUtility.ParseQueryString(string.Empty);
// Request headers
client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", bingKey);
// Request parameters
queryString["q"] = "microsoft";
queryString["count"] = "10";
queryString["offset"] = "0";
queryString["mkt"] = "en-us";
queryString["safeSearch"] = "Moderate";
var uri = "https://api.cognitive.microsoft.com/bing/v5.0/news/search?" + queryString;
var response = await client.GetStringAsync(uri);
var jsonResult = JsonConvert.DeserializeObject<BingJson>(response);
string title = jsonResult.value[0].name.ToString();
}
With the jsonResult.value[0] you can loop through the results. First results is at [0] position.
I Created a model class looking at the bing search response json. It looks like,
public class BingJson
{
public string _type { get; set; }
public Instrumentation instrumentation { get; set; }
public string readLink { get; set; }
public int totalEstimatedMatches { get; set; }
public Value[] value { get; set; }
}
public class Instrumentation
{
public string pingUrlBase { get; set; }
public string pageLoadPingUrl { get; set; }
}
public class Value
{
public string name { get; set; }
public string url { get; set; }
public string urlPingSuffix { get; set; }
public Image image { get; set; }
public string description { get; set; }
public About[] about { get; set; }
public Provider[] provider { get; set; }
public DateTime datePublished { get; set; }
public string category { get; set; }
}
public class Image
{
public Thumbnail thumbnail { get; set; }
}
public class Thumbnail
{
public string contentUrl { get; set; }
public int width { get; set; }
public int height { get; set; }
}
public class About
{
public string readLink { get; set; }
public string name { get; set; }
}
public class Provider
{
public string _type { get; set; }
public string name { get; set; }
}

Answer 2

With this model, I am able to get the desired result. The Model which is presented in the other answer is not working in my case.
namespace BingSearchBot
{
public class RootObject
{
public string _type { get; set; }
public WebPages webPages { get; set; }
public RelatedSearches relatedSearches { get; set; }
public RankingResponse rankingResponse { get; set; }
}
public class WebPages
{
public string webSearchUrl { get; set; }
public int totalEstimatedMatches { get; set; }
public List<Value> value { get; set; }
}
public class Value
{
public string id { get; set; }
public string name { get; set; }
public string url { get; set; }
public List<About> about { get; set; }
public string displayUrl { get; set; }
public string snippet { get; set; }
public List<DeepLink> deepLinks { get; set; }
public string dateLastCrawled { get; set; }
public List<SearchTag> searchTags { get; set; }
}
public class About
{
public string name { get; set; }
}
public class DeepLink
{
public string name { get; set; }
public string url { get; set; }
public string snippet { get; set; }
}
public class SearchTag
{
public string name { get; set; }
public string content { get; set; }
}
public class Value2
{
public string text { get; set; }
public string displayText { get; set; }
public string webSearchUrl { get; set; }
}
public class RelatedSearches
{
public string id { get; set; }
public List<Value2> value { get; set; }
}
public class Value3
{
public string id { get; set; }
}
public class Item
{
public string answerType { get; set; }
public int resultIndex { get; set; }
public Value3 value { get; set; }
}
public class Mainline
{
public List<Item> items { get; set; }
}
public class RankingResponse
{
public Mainline mainline { get; set; }
}
}
