        {
            string bucketName = "bucketName";
            string sharedkeyFilePath = GetFilePath("privateKey.json");
            GoogleCredential credential = null;
            using (var jsonStream = new FileStream(sharedkeyFilePath, FileMode.Open,
                FileAccess.Read, FileShare.Read))
            {
                credential = GoogleCredential.FromStream(jsonStream);
            }
            var storageClient = StorageClient.Create(credential);
            string filetoUpload = GetFilePath("demo.txt");
            using (var fileStream = new FileStream(filetoUpload, FileMode.Open,
                FileAccess.Read, FileShare.Read))
            {
                storageClient.UploadObject(bucketName, "demo.txt", "text/plain", fileStream);
            }
            Console.WriteLine("uploaded the file successfully");
            Console.ReadLine();
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }
    public static string GetFilePath(string filename)
    {
        return GetFilePath(Assembly.GetCallingAssembly().Location, filename);
    }

    {
        return path.Substring(0, path.LastIndexOf("\")) + @"" + filename;
    }
