IList.IsReadOnly Property

CollectionBase.IList.IsReadOnly Property

 

Gets a value indicating whether the CollectionBase is read-only.

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

Private ReadOnly Property IsReadOnly As Boolean Implements IList.IsReadOnly

Property Value

Type: System.Boolean

true if the CollectionBase is read-only; otherwise, false. The default is 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.
