BitArray.IsReadOnly 属性


获取一个值,该值指示 BitArray 是否为只读。Gets a value indicating whether the BitArray is read-only.

 property bool IsReadOnly { bool get(); };
public bool IsReadOnly { get; }
member this.IsReadOnly : bool
Public ReadOnly Property IsReadOnly As Boolean



此属性始终为 falseThis property is always false.


BitArray 实现 IsReadOnly 属性,因为它是接口所必需的 System.Collections.IListBitArray implements the IsReadOnly property because it is required by the System.Collections.IList interface.

在创建只读集合后,该集合不允许添加、移除或修改元素。A collection that is read-only does not allow the addition, removal, or modification of elements after the collection is created.

只读集合就是一个集合,其中包含阻止修改集合的包装器;因此,如果对基础集合进行了更改,只读集合将反映这些更改。A collection that is read-only is simply a collection with a wrapper that prevents modifying the collection; therefore, if changes are made to the underlying collection, the read-only collection reflects those changes.

此方法是一种 O(1) 操作。This method is an O(1) operation.
