IDictionary.IsFixedSize Property

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

Namespace:  System.Collections
Assembly:  mscorlib (in mscorlib.dll)
bool IsFixedSize { get; }

Property Value

Type: System.Boolean
true if the IDictionary object has a fixed size; otherwise, false.

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.

The following code example demonstrates how to implement the IsFixedSize property. This code example is part of a larger example provided for the IDictionary class.

public bool IsFixedSize { get { return false; } }
