Azure Storage Queues

Overview

Azure Queue storage provides reliable messaging for asynchronous communication between components of cloud services. It enables you to store large numbers of messages that can be accessed from anywhere via HTTP or HTTPS.

Key Concepts

Queue – A container for messages.
Message – A piece of data, up to 64 KB in size.
Visibility timeout – The period a message remains invisible after being retrieved.
TTL (time‑to‑live) – Maximum lifetime of a message (up to 7 days).

Creating a Queue

using Azure.Storage.Queues;
using Azure.Storage.Queues.Models;

string connectionString = "your_connection_string";
string queueName = "myqueue";

QueueClient queueClient = new QueueClient(connectionString, queueName);
queueClient.CreateIfNotExists();

Sending a Message

await queueClient.SendMessageAsync("Hello, Azure Queue!");

Receiving Messages

QueueMessage[] retrievedMessages = await queueClient.ReceiveMessagesAsync(maxMessages: 5);

foreach (QueueMessage msg in retrievedMessages)
{
    Console.WriteLine($"Message: {msg.MessageText}");
    await queueClient.DeleteMessageAsync(msg.MessageId, msg.PopReceipt);
}
