After getting data through api, how to post in sql using c#

Question

I have C# Console Application where I'm getting data from google-news-api and after that I want to post whole data to my sql server. So how is it possible 

namespace ConsoleApp {
 class Program {
  static void Main(string[] args) {
   SqlConnection conn = new SqlConnection(@ "Server=SQLEXPRESS;Initial Catalog=testingnews;User Id=abctesting;Password=sabc;");
   conn.Open();
   SqlCommand cmd = new SqlCommand("insert into newstbl values ('50AE4E66-07C0-4AB0-936B-2778AFCB9787', '', '', '', '', '', '', '', '', '', '', '', 0, '', 0, '', 1, 0, '')", conn);
   SqlDataReader reader = cmd.ExecuteReader();
   while (reader.Read()) {
    Console.WriteLine("{0},{1}", reader.GetString(0), reader.GetString(1));
    Console.ReadLine();
   }
   reader.Close();
   conn.Close();
   try {
    GetNewsDetails().Wait();
   } catch (Exception ex) {}
  }

  public static async Task < string > GetNewsDetails() {
   using(var _http = new HttpClient()) {
    _http.BaseAddress = new Uri("https://newsapi.org/v2/");
    _http.DefaultRequestHeaders.Clear();
    _http.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    HttpResponseMessage response = await _http.GetAsync("everything?sources=&q=bbc-news&sortBy=publishedAt&pageSize=80&apiKey=4dbc17e007ab436fb66416009dfb59a8");
    response.EnsureSuccessStatusCode();
    using(HttpContent content = response.Content) {
     string responseBody = await content.ReadAsStringAsync();
     Console.WriteLine(responseBody);  // In responseBody I'm getting multiple data
     Console.ReadLine();
    }
   }
   return "objNewsRoot";
  }


 }
}
