Property Value

Type: System.Boolean

true if the NameObjectCollectionBase instance is read-only; otherwise, false.

A collection that is read-only does not allow the addition, removal, or modification of elements after the collection is created.

A collection that is read-only is simply a collection with a wrapper that prevents modifying the collection; therefore, if changes are made to the underlying collection, the read-only collection reflects those changes.

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

The following code example creates a read-only collection.
