StringCollection.IList.IsReadOnly Property

Gets a value indicating whether the StringCollection object is read-only.

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

bool IList.IsReadOnly { get; }

Property Value

Type: System.Boolean
true if the StringCollection object is read-only; otherwise, false. The default is false.

Implements

IList.IsReadOnly

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.
