Shortening the large bulk url to short by using Google URL Shortener.
Before implementing the bulk url shortener, you need to create an API key for Google API Web Request. 

Follow the below steps to create Google API Key

1) Go to the following link
2) Click on "GET A KEY, Select or Create a new project.

3) Now Click on "Enable API". (Sample API Key :  AIzaSyAvjD359ibDC-*****S8A73ZdTZ*****)

Now, You are ready to start developing with Google URL Shortener API.

class Program
        private const string key = "AIz****YnrVv*****iBnHfv5OIi****CxHh0";
        static List<string> shortUrlList = new List<string>();

        static void Main(string[] args)
            var ds = new DataSet();
            string connectionString = ConfigurationManager.ConnectionStrings["DBString"].ConnectionString;
            using (var conn = new SqlConnection(connectionString))
                using (SqlCommand cmd = new SqlCommand("get_log_url", conn))
                    cmd.CommandType = CommandType.StoredProcedure;
                    var adapter = new SqlDataAdapter(cmd);

            if (ds.Tables.Count > 0)
                foreach (DataRow dr in ds.Tables[0].Rows)
                    string longUrl = dr["longurl"].ToString();
                    string shortUrl = GoogleUrlShortener(longUrl);


        public static string GoogleUrlShortener(string longUrl)
            string finalURL = "";
            string post = "{\"longUrl\": \"" + longUrl + "\"}";
            string shortUrl = longUrl;
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("" + key);
                request.ServicePoint.Expect100Continue = false;
                request.Method = "POST";
                request.ContentLength = post.Length;
                request.ContentType = "application/json";
                using (Stream requestStream = request.GetRequestStream())
                    byte[] postBuffer = Encoding.ASCII.GetBytes(post);
                    requestStream.Write(postBuffer, 0, postBuffer.Length);
                using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
                    using (Stream responseStream = response.GetResponseStream())
                        using (StreamReader responseReader = new StreamReader(responseStream))
                            string json = responseReader.ReadToEnd();

                            JObject jsonResult = JObject.Parse(json);
                            finalURL = jsonResult["id"].ToString();
            catch (Exception ex)
                System.Console.WriteLine(" Success -- > " + ex.StackTrace);
            return finalURL;

Result : 

Long URL :
Short URL :

Hope, This article helps you to shortning bulk long url.
