using Newtonsoft.Json;
namespace apidemo

         const String apiKey= "My APi kEy";
        static void Main(string[] args)

            Console.ReadLine();
        }
        static async public void getdata(String code)
        {
            try
            {
                using (var client = new HttpClient())
                {
                   

                    var response = await client.GetStringAsync(String.Format("https://maps.googleapis.com/maps/api/place/autocomplete/json?key="+ apiKey + "&input=" +code));
               
                    Console.WriteLine(response);
                   



                }
            }
            catch (Exception ex) {

    There is not difference between .NET Framework and ASP.NET except UI/Controller related code. Actually, ASP.NET is also a .NET Framework based app. –  Jul 04 '20 at 06:10

    Why don't you using Google API libraries for .NET? It should support .NET Standard that is not depend on any runtime platform. .NET Framework, .NET, .NET Core(lagacy of .NET), ASP.NET, ASP.NET Core whatever any of .NET CLR. Therefore, there is no difference. –  Jul 04 '20 at 06:41

    Anyway, if you don't using any of library, the HTTP is global standard protocol. Therefore you can call the Google APIs manually by `HttpClient` it is included .NET Standard. It means, all of .NET runtimes support the class. –  Jul 04 '20 at 06:45
  • Can you share any helpful content that how to use Google API libraries for .NET in my application – Engr. Khuram Shahzad Jul 04 '20 at 06:47
  • Search the NuGet like this. https://www.nuget.org/packages/Google.Apis I don't know what packages related with it. –  Jul 04 '20 at 06:49

  • Plaese edit your question inlcude your code and describe any issues you are having with your current solution. – Linda Lawton - DaImTo Jul 04 '20 at 14:00
  • @DaImTo OK..... – Engr. Khuram Shahzad Jul 04 '20 at 14:10
  • @DaImTo i have implement some how but now i am stuck here , How to get desire result from 'responce' – Engr. Khuram Shahzad Jul 04 '20 at 14:59
  • Have you tried Googleing it? https://stackoverflow.com/q/6620165 Your not going to get the result directly from that response the response is in JSON its going to be up to you to format it. No one here is going to code your project for you your going to have to do this. – Linda Lawton - DaImTo Jul 04 '20 at 15:08

If we look at the documentation for the Google Places API, we can see the format of the JSON that a request to the API returns. You can traverse the json object and get your required values as in below snippet.

JObject objectContainer = response.Value<JObject>("candidates");

foreach (KeyValuePair<string, JToken> tag in objectContainer)
{
    if(tag.key=="formatted_address")
        var address = tag.value;
    if(tag.key=="name")
        var name = tag.value;
}

With a simple HTTP request to the Google Places API, we can then use above code to get required fields.

using (var client = new HttpClient())
{
    var response = await client.GetStringAsync("https://maps.googleapis.com/maps/api/place/findplacefromtext/json?input=YOUR_POSTCODE&inputtype=textquery&&fields=photos,formatted_address,name,opening_hours,rating&key=YOUR_API_KEY");
    var result = JsonConvert.DeserializeObject<PlacesApiQueryResponse>(response);
}
