Question

I am writing an application in C#. In this application I am getting data from different ports. Here I want to create a queue with the name equal to the portnumber whenever a new port starts sending data. Can I create such a queue?

If you mean you want to create a queue of received data for each port that is being used, you’d be best having a keyed collection of queues. These queues would be keyed by the port number. So perhaps use a Dictionary<int, Queue<Data>>. Then when a request comes in, you can check to see if the port already has a queue; if so, add to that queue; if not, create the queue. i.e.

private Dictionary<int, Queue<Data>> mPortQueues = new Dictionary<int, Queue<Data>>();

public void ReceiveData(int portNumber, Data data)
{
    Queue<Data> queue;

    // See if we have a queue
    if (!mPortQueues.TryGetValue(portNumber, out queue))
    {
        // No queue for this port, so create and cache
        queue = new Queue<Data>();

        mPortQueues.Add(portNumber, queue);
    }

    // Queue the data
    queue.Enqueue(data);
}
