The MessageQueue class in StorageClient contains the polling inbuilt  infrastructure and delivers the message via eventing:

mqObj.MessageReceived += new MessageReceivedEventHandler(mqObj_MessageReceived);
mqObj.PollInterval = 1000; // poll interval in milliseconds
mqObj.StartReceiving(); // starts polling

The event handler fires whenever a message is received, in addition, when there are no more messages the client will begin polling the queue at the  PollInterval

In this code sample no timeout is set and so the default is selected from the Timeout property of the MessageQueue class (which in turn defaults to 30 seconds).

1. Set up Authentication Details and Create a New Queue

The below code adds the the storage authentication details, creates a queue storage object (which is the storage container that the Message Queues are placed in), then creates a message queue and finally adds a message to that queue:

string accName = “devacc1″;

string accKey = “accountKeyStringxxxx”;

string address = “http://127.0.0.1:10001″;

StorageAccountInfo acObj = new StorageAccountInfo(new Uri(address), null, accName, accKey);

QueueStorage qsObj = QueueStorage.Create(acObj);

MessageQueue mqObj = qsObj.GetQueue(“azureSupportString”);

mq.CreateQueue();

Message msgObj = new Message(DateTime.Now.ToString());

mqObj.PutMessage(msgObj);

2. Receiving a Message from the Queue

The code for receiving a message from a queue is very straightforward. Use the GetMessage method of the MessageQueue with the time out in seconds passed in as a parameter. This timeout is the time that routine has a lock on the message, if it is not deleted within the timeout time other processes will be able to access it.
The GetMessage method returns null if there is no message on the queue so your code needs to check for that. Also note that the message remains on the queue if it is not deleted so call the DeleteMessage method to delete the message.

Message msgObj = mqObj.GetMessage(3);
if (msgObj != null)
{
Console.WriteLine(msgObj.ContentAsString());
mqObj.DeleteMessage(msgObj);
}

We can also add Queue Polling to this routine
