備註

具有固定大小的集合不允許在集合建立後新增或移除項目，但允許對現有項目進行修改。A collection with a fixed size does not allow the addition or removal of elements after the collection is created, but it allows the modification of existing elements.

具有固定大小的集合只是具有包裝函式的集合，可防止新增和移除元素;因此，如果對基礎集合進行了變更，包括新增或移除專案，則固定大小的集合會反映這些變更。A collection with a fixed size is simply a collection with a wrapper that prevents adding and removing elements; therefore, if changes are made to the underlying collection, including the addition or removal of elements, the fixed-size collection reflects those changes.

抓取這個屬性的值是一項作業 O(1) 。Retrieving the value of this property is an O(1) operation.
