Dictionary<TKey, TValue>.IDictionary.IsFixedSize Property

 

Gets a value indicating whether the IDictionary has a fixed size.

Namespace:   System.Collections.Generic
Assembly:  mscorlib (in mscorlib.dll)

bool IDictionary.IsFixedSize { get; }

Property Value

Type: System.Boolean

true if the IDictionary has a fixed size; otherwise, false. In the default implementation of Dictionary<TKey, TValue>, this property always returns false.

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.

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.

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