ASP.NET Web API, XML Web API daha önce de belirttiğim yerini aldı.

Ben dedim post güncelleştirilmiş bir cevap beri en çok bu tepkiler erken 2012 ve bu konuyu bir üst sonuçlar ne zaman bir Google arama yapmak için "arama dinlendirici hizmeti c#".

Microsoft geçerli rehberlik API İstemci Kitaplıkları Microsoft ASP.NET Web Dinlendirici bir hizmetini kullanmak için kullanmaktır. Bu NuGet paketi, Microsoft olarak kullanılabilir.AspNet.WebApi.İstemci.

Örnek ASP.NET Web API İstemci Kitaplığı kullanılarak uygulanan gibi görünür:

using System;
using System.Collections.Generic;
using System.Net.Http;
using System.Net.Http.Headers;

namespace ConsoleProgram
{
    public class DataObject
    {
        public string Name { get; set; }
    }

    public class Class1
    {
        private const string URL = "https://sub.domain.com/objects.json";
        private string urlParameters = "?api_key=123";

        static void Main(string[] args)
        {
            HttpClient client = new HttpClient();
            client.BaseAddress = new Uri(URL);

            // Add an Accept header for JSON format.
            client.DefaultRequestHeaders.Accept.Add(
            new MediaTypeWithQualityHeaderValue("application/json"));

            // List data response.
            HttpResponseMessage response = client.GetAsync(urlParameters).Result;  // Blocking call!
            if (response.IsSuccessStatusCode)
            {
                // Parse the response body. Blocking!
                var dataObjects = response.Content.ReadAsAsync<IEnumerable<DataObject>>().Result;
                foreach (var d in dataObjects)
                {
                    Console.WriteLine("{0}", d.Name);
                }
            }
            else
            {
                Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
            }  
        }
    }
}
