            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", "<key>");//Face API key

            // Request parameters

            queryString["returnFaceId"] = "true";

            queryString["returnFaceLandmarks"] = "false";

            queryString["returnFaceAttributes"] = "age";

            var uri = "https://api.cognitive.azure.cn/face/v1.0/detect?" + queryString;

            HttpResponseMessage response;

            // Request body

            byte[] byteData = Encoding.UTF8.GetBytes("{\"url\":\"http://imgsrc.baidu.com/baike/pic/item/4034970a304e251ff1e3819aa486c9177f3e53bf.jpg\"}");//图片URL

            using (var content = new ByteArrayContent(byteData))

            {

                response = await client.PostAsync(uri, content);

            }

            //response result

            string result = await response.Content.ReadAsStringAsync();

            Console.WriteLine("response:" + result);

        }

    }
