Collection<T>.IList.IsFixedSize Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

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

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

Syntax

'Declaration
Private ReadOnly Property IsFixedSize As Boolean
    Implements IList.IsFixedSize
bool IList.IsFixedSize { get; }

Property Value

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

Implements

IList.IsFixedSize

Remarks

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.
