That is like 1 2 3 4 0 and again 2 3 4 0 1.

Answer 1

What class are you using to implement your queue?

If using a List<>, you could do it like this:

        List<MyQueueEntry> queue = new List<MyQueueEntry>();

        // Add stuff into the queue list

        // take the head entry, remove it from the queue and add it to the tail
        MyQueueEntry head = queue.First();
        queue.RemoveAt(0);
        queue.Add(head);
