How to send Batch Push Notification Android on C# .Net

I have two methods for sending Push Notification First example:

public void SendPushNotification(String regId, String message, String googleAppId, String senderId)
    {
        var value = message;
        var tRequest = WebRequest.Create(ConfigurationManager.AppSettings["RequestUrl"]);
        tRequest.Method = "post";
        tRequest.ContentType = " application/x-www-form-urlencoded;charset=UTF-8";
        tRequest.Headers.Add(string.Format("Authorization: key={0}", googleAppId));

        tRequest.Headers.Add(string.Format("Sender: id={0}", senderId));

        string postData = "data.message=" + value + "&registration_id=" + regId + "";
        var byteArray = Encoding.UTF8.GetBytes(postData);
        tRequest.ContentLength = byteArray.Length;

        var dataStream = tRequest.GetRequestStream();
        dataStream.Write(byteArray, 0, byteArray.Length);
        dataStream.Close();

        var tResponse = tRequest.GetResponse();

        dataStream = tResponse.GetResponseStream();

        if (dataStream != null)
        {
            var tReader = new StreamReader(dataStream);

            String sResponseFromServer = tReader.ReadToEnd();

            var httpResponse = (HttpWebResponse) tResponse;
            string statusCode = httpResponse.StatusCode.ToString();

            tReader.Close();
        }
        if (dataStream != null) dataStream.Close();
        tResponse.Close();
    }

Second example. I use PushBroker from PushSharp

            var push = new PushBroker();
            push.RegisterGcmService(new GcmPushChannelSettings(apikey));
            push.QueueNotification(
                new GcmNotification().ForDeviceRegistrationId(deviceId).WithJson(json));

And this methods works good. I know how send batch push notification (i mean one message and song for a list of devices). I saw example there How to send batch notifications in GCM using PushSharp

But I would like to send push notification in batch, where for every device i have some special message and some song name. So did You know any solution for my problem?

You can't send different messages to different Registration IDs in batch.

The JSON request that Google Cloud Messaging accepts supports a single payload (inside the data element) and 1 to 1000 Registration IDs. That means in each request you can either send one message to one Registration ID or the same message to multiple Registration IDs.
