Microsoft Linguistic Analysis API example HttpUtility does not exist

Question

I'm trying to check Microsoft Linguistic Analysis API, basic example, so I have subscribed and addad my Key 1 in Ocp-Apim-Subscription-Key and Key 2 into the subscription key here client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", "{subscription key}");.

Then I add Newtonsoft.Json with Manage NuGet Packages into the References of Application, even it is not listed in using of particular example using Newtonsoft.Json; using bNewtonsoft.Json.Serialization; not sure, I'm new with this tool.

I'm trying to check this example Linguistics API for C# to get some natural language processing results for text analysis mainly of Verb and Noun values according to this example results So I'm not sure if I'm on the right direction with this example, or possible I've missed something to install, maybe I need some additions. I found this Analyze Method not sure how and if I have to use it for this particular goal.

But seems like something is wrong with var queryString = HttpUtility.ParseQueryString(string.Empty); and HttpUtility does not exist.

using System; using System.Net.Http.Headers; using System.Text; using System.Net.Http; using System.Web; namespace CSHttpClientSample { static class Program { static void Main() { MakeRequest(); Console.WriteLine("Hit ENTER to exit..."); Console.ReadLine(); } static async void MakeRequest() { var client = new HttpClient(); var queryString = HttpUtility.ParseQueryString(string.Empty); // Request headers client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", "{subscription key}"); var uri = "https://westus.api.cognitive.microsoft.com/linguistics/v1.0/analyze?" + queryString; HttpResponseMessage response; // Request body byte[] byteData = Encoding.UTF8.GetBytes("{body}"); using (var content = new ByteArrayContent(byteData)) { content.Headers.ContentType = new MediaTypeHeaderValue("< your content type, i.e. application/json >"); response = await client.PostAsync(uri, content); } } } }

@Ken White Hello, hope now is better

You can create a new writeable instance of HttpValueCollection by calling System.Web.HttpUtility.ParseQueryString(string.Empty), and then use it as any NameValueCollection, like this:

NameValueCollection queryString = System.Web.HttpUtility.ParseQueryString(string.Empty);

Hello, I tried but it says the method or operation is not implemented

I think you did not used the Namespace for this class. You have to use System.Collections.Specialized Namespace to access NameValueCollection class.

Try adding a reference to System.Web, and possibly to System.Runtime.Serialization.
