How to prevent an item from being used more than a certain count?

Trying to implement a ConcurrentQueue that prevents an item from being used more than a specific # of times. For example, I want a User object that can be Dequeued 10 times, and after that, the user would be logged off and disposed.

Obviously fairly easy to implement by using a Dictionary and keeping track of the number开发者_JAVA百科 of times each object has been used, in conjunction with the ConcurrentQueue. However, just wondering if anybody has any neat ideas for managing this?

Something like this in java:

interface Dequeable
{
    public int dequed();
}

class ConcurrentQueueImpl extends ConcurrentQueue
{
    ..................
    .................

    @override
    public Dequeable deque()
    {
        Dequeable obj=.................;

        **if(obj.dequed()>=10)**
        {
            // dispose off obj
            return null;
        }
        return obj;
    }

}

class SampleDequeableClass implements Dequeable
{
    private int dequedCounter=0;
    public int dequed()
    {
        dequedCounter++;
        if(dequedCounter>=10)
        {
            // log off this object...
        }
    }
}

Create your own thread-safe Queue<T>, just like the days without C#4.0. And in its Dequeue method, record the use count. You needn't modify the original class/interface of the item. You can have another Dictionary<IFoo, int> as a use counter.
