Check RabbitMQ queue size from client

Question

Does anyone know if there\'s a way to check the number of messages in a RabbitMQ queue from a client application?

I\'m using the .NET client library.

If you want to do this in .NET, check which version of the client library you are using.

I'm using the 2.2.0 version and I had to use BasicGet(queue, noAck).
In this version of the library, QueueDeclare() only returns a string containing the queue name.

BasicGetResult result = channel.BasicGet("QueueName", false);
uint count = result != null ? result.MessageCount : 0;

I know from the 2.6.1 version, QueueDeclare() returns an object of type QueueDeclareOk.

QueueDeclareOk result = channel.QueueDeclare();
uint count = result.MessageCount;

Alternatively, you can call from the command line:

\sbin\rabbitmqctl.bat list_queues

And you see the following output:

Listing queues...
QueueName 1
...done.
