Property Value

Type: System::Boolean
true if the DictionaryBase object has a fixed size; otherwise, false. The default is false.

Implements

IDictionary::IsFixedSize

A collection with a fixed size does not allow the addition or removal of elements after the collection is created, but does allow the modification of existing elements.

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.

Retrieving the value of this property is an O(1) operation.
