SortedList<TKey,TValue>.IDictionary.IsFixedSize 屬性


取得值,指出 IDictionary 是否有固定的大小。Gets a value indicating whether the IDictionary has a fixed size.

property bool System::Collections::IDictionary::IsFixedSize { bool get(); };
bool System.Collections.IDictionary.IsFixedSize { get; }
member this.System.Collections.IDictionary.IsFixedSize : bool
 ReadOnly Property IsFixedSize As Boolean Implements IDictionary.IsFixedSize



如果 true 有固定的大小,即為 IDictionary;否則為 falsetrue if the IDictionary has a fixed size; otherwise, false. SortedList<TKey,TValue> 的預設實作中,這個屬性一律會傳回 falseIn the default implementation of SortedList<TKey,TValue>, this property always returns false.



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.

擷取這個屬性的值是一種 O(1) 運算。Retrieving the value of this property is an O(1) operation.
