System.Collections.Hashtable.IsReadOnly Property

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


public virtual bool IsReadOnly { get; }


true if the current 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.
