固定大小的队列，可在新入队时自动使旧值出队

我将编写一个包装器类，该类在Enqueue上将检查Count，然后在计数超过限制时出队列。

 public class FixedSizedQueue<T> {     ConcurrentQueue<T> q = new ConcurrentQueue<T>();     private object lockObject = new object();     public int Limit { get; set; }     public void Enqueue(T obj)     {        q.Enqueue(obj);        lock (lockObject)        {T overflow;while (q.Count > Limit && q.TryDequeue(out overflow)) ;        }     } }
