copied!<p>You'll have to create a <code>QueueSet</code> that implements <code>ICollection<T></code>. It can be a wrapper class that contains a collection as a backing store. It can be implemented as follows:</p> <pre><code>class QueueSet<T> : ICollection<T> { List<T> queue=new List<T>(); int maximumSize; public QueueSet(int maximumSize){ if(maximumSize<0) throw new ArgumentOutOfRangeException("maximumSize"); this.maximumSize=maximumSize; } public T Dequeue(){ if(queue.Count>0){ T value=queue[0]; queue.RemoveAt(0); return value; } return default(T); } public T Peek(){ if(queue.Count>0){ return queue[0]; } return default(T); } public void Enqueue(T item){ if(queue.Contains(item)){ queue.Remove(item); } queue.Add(item); while(queue.Count>maximumSize){ Dequeue(); } } public int Count { get { return queue.Count; } } public bool IsReadOnly { get { return false; } } public void Add(T item) { Enqueue(item); } public void Clear() { queue.Clear(); } public bool Contains(T item) { return queue.Contains(item); } public void CopyTo(T[] array, int arrayIndex) { foreach(T value in queue){ if(arrayIndex>=array.Length)break; if(arrayIndex>=0){ array[arrayIndex]=value; } arrayIndex++; } } public bool Remove(T item) { if(Object.Equals(item,Peek())){ Dequeue(); return true; } else { return false; } } public IEnumerator<T> GetEnumerator() { return queue.GetEnumerator(); } System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator() { return queue.GetEnumerator(); } } </code></pre> <p>I release this code into the public domain.</p>
