How to Receive all files from Azure Service Bus Queue in D365 FO

Hello All,
I have a scenario to pick all the available Files (Invoice files) from Azure service bus queue and process the file inside D365 FO.
 
As of now with the code below I am able to pick 1 file(First file)
For Example if the Queue has 5 Invoice files, my code should pick 5 invoice files  together and process it.
 
.Net code to read message: class name /AzureQueueLibrary/
public class ReceiveAzureQueue
{
        QueueClient queueClient;
        BrokeredMessage message;
 
        public void connect(string connectionString)
        {
            queueClient = QueueClient.CreateFromConnectionString(connectionString, ReceiveMode.PeekLock);
        }
 
        public Stream readMessage()
        {            
            message = queueClient.Receive();            
            var stream = message.GetBody<Stream>();          
            return (stream);
        }
 
        public void completeMessage()
        {
            queueClient.Complete(message.LockToken);
        }
 
        public void close()
        {
            queueClient.Close();
        }
    }
 
D365 Code to process the file:
AzureQueueLibrary.ReceiveAzureQueue ReceiveAzureQueue = new AzureQueueLibrary.ReceiveAzureQueue();               
ReceiveAzureQueue.connect(connectionString);       
var stream = ReceiveAzureQueue.readMessage();
 
Above readMessage() picks only first file now. How to check the count of files and get all the files into D365 and process the same.
Let me know if any sample code/reference available
 
Regards,
Monika

    Hello @Martin Dráb ,
     
    Thank you for providing the clarity. 
     
    Now I am able to iterate the queue and process messages at a time and finally once I do not have any message in queue, I am closing the queue connection.
     
    Regards,
    Monika

    You shouldn't try to check the number of messages. It's a queue, therefore you remove messages at one end and new messages may be being added at the other end. Let's say that there are three messages, but before you process them, two more are added. With your solution, you'd ignore the last two.
     
    You should simply take a message from a queue, process it, then take another message from a queue and so on, until there is no message remaining.
