Add Storage Queue Message

I’ve written quite extensively in the past about Azure, and Azure Storage. I recently needed to add a message to an Azure storage queue, and realised that I had never written a post about that, specifically. As with many Azure focused .Net activities, it’s not too complex; but I do like to have my own notes on things.

If you’ve arrived at this post, you may find it’s very similar to the Microsoft documentation.

How to add a message

The first step is to install a couple of NuGet packages:

Install-Package Microsoft.Azure.Storage.Common
Install-Package Microsoft.Azure.Storage.Queue

My preference for these kinds of things is to create a helper: largely so that I can mock it out for testing; however, even if you fundamentally object to the concept of testing, you may find such a class helpful, as it keeps all your code in one place.

 public class StorageQueueHelper
        private readonly string _connectionString;
        private readonly string _queueName;

        public StorageQueueHelper(string connectionString, string queueName)
            _connectionString = connectionString;
            _queueName = queueName;

        public async Task AddNewMessage(string messageBody)
            var queue = await GetQueue();

            CloudQueueMessage message = new CloudQueueMessage(messageBody);
            await queue.AddMessageAsync(message);

        private async Task<CloudQueue> GetQueue()
            CloudStorageAccount storageAccount = CloudStorageAccount.Parse(_connectionString);
            CloudQueueClient queueClient = storageAccount.CreateCloudQueueClient();
            CloudQueue queue = queueClient.GetQueueReference(_queueName);
            await queue.CreateIfNotExistsAsync();

            return queue;

The class above works for a single queue, and storage account. Depending on your use case, this might not be appropriate.

The GetQueue() method here is a bit naughty, as it actually changes something (or potentially changes something). Essentially, all it’s doing is connecting to a cloud storage account, and then getting a reference to a queue. We know that the queue will exist, because we’re forcing it to (CreateIfNotExistsAsync()).

Back in AddNewMessage(), once we have the queue, it’s trivial to simply create the message and add it.
