mutual exclusion issue

Hello

I've got an application which uses a collection in this case a queue from diffrent threads. An object gets enqueued in one thread while another gets dequeued in a different thread. These actions might accure simultaneously which would resolve in an exception such as argument out of range exception , when the collections counter is being redefined.

Now im looking for a "good looking" and right way to exclude these actions from one another

(1) What I mean by "good looking" is that i don't want to create my own collection derived from this one wich includes a lock(object) mechanism

(2) I don't want to use the brain storming idea i had, which is pretty "ugly"

enqueueOk = false;
while (enqueueOk)
{
       try
       {
           Qsockets.Enqueue(currentSoc);
           reEnqueueOk = true;
       }
       catch { } 
}

I thought of course using the a lock or a mutex but that would be the case only if I wrap these actions in a procedure which would be called from each thread, and decide either to enqueue or dequeue which would also be long and "ugly"

Any ideas would be appricated ...
