'Declaration
Private ReadOnly Property IsFixedSize As Boolean 
	Implements IList.IsFixedSize

Property Value

Type: System.Boolean
true if the IList has a fixed size; otherwise, false. In the default implementation of List(Of T), this property always returns false.

Implements

IList.IsFixedSize

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.
