The de facto is HttpClient, which all of them can be used in an ASP.NET Web form, ASP.NET MVC, Windows form, console program, Windows service or even in ASP.NET WEBAPI that consumes another ASP.NET WebAPI etc. and etc .NET programs.
Code was shown to you in another thread of yours on how to use HTTPclient. You seem to be making things harder than what it should be. There are plenty of code examples and articles by using Bing or Google that can help you.
The other thing is learn how to use Json.NET on the client-side/code-behind.

The simplest to use is WebClient(). And it's back to the DTO that for some reason you are ignoring. And how is HTTPS involved?
public Function GetProjsByUserIdApi(userid As String) as List(of DtoProject) Implements IWebApi.GetProjsByUserIdApi
dim dtoprojects = new List(Of DtoProject)
dim url = "http://localhost/WebApiVB/api/project/GetProjectsByUserId?userid=" & userid
Using webclient As New WebClient
dim json = webclient.DownloadString(url)
Dim projects = JsonConvert.DeserializeObject(of List(Of DtoProject))(json)
dtoprojects = projects
End Using
Return dtoprojects
End Function

Hi,
So you are trying to consume this API from C#.
See for example http://json2csharp.com/ to generate a class (or you have one already in your web API) and https://docs.microsoft.com/en-us/aspnet/web-api/overview/advanced/calling-a-web-api-from-a-net-client to see how to consume this API using HttpClient.
For basic auth see https://gist.github.com/bryanbarnard/8102915

I've this,
private char[] serializedObject; ASCIIEncoding encoder = new ASCIIEncoding(); byte[] data = encoder.GetBytes(serializedObject); // a json object, or xml, whatever... HttpWebRequest request = WebRequest.Create("https://localhost:44334/api/erp/GetEmployee") as HttpWebRequest; request.Method = "POST"; request.ContentType = "application/json; charset=utf-8"; request.Headers.Add("apiuser", "33889"); request.ContentLength = data.Length; request.Expect = "application/json"; request.GetRequestStream().Write(data, 0, data.Length); HttpWebResponse response = request.GetResponse() as HttpWebResponse;The result was --> Array cannot be null. Parameter name: chars
