ReadOnlyCollection<T>.IList.IsFixedSize Property


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

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

bool IList.IsFixedSize { get; }

Property Value

Type: System.Boolean

true if the IList has a fixed size; otherwise, false. In the default implementation of ReadOnlyCollection<T>, this property always returns true.

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.

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

This member is an explicit interface member implementation. It can be used only when the ReadOnlyCollection<T> instance is cast to an IDisposable interface.
