Sending messages asynchronously

Jamaa Smpp Client provides an asynchronous version of the SendMessage method for sending messages asynchronously without waiting for the operation to complete.

The following code snippet shows how to send message asynchronously.

TextMessage msg = new TextMessage();
//set msg properties

SmppClient client = GetSmppClient();
client.BeginSendMessage(msg, SendMessageCompleteCallback, client);
//continue with other stuff

Below is a method that will be called after the asynchronous operation completes:

private void SendMessageCompleteCallback(IAsyncResult result)
{
    SmppClient client = (SmppClient)result.AsyncState;
    client.EndSendMessage(result);
}
