            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);
            }
