SortedList<TKey,TValue>.IDictionary.IsReadOnly Property


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

property bool System::Collections::IDictionary::IsReadOnly { bool get(); };
bool System.Collections.IDictionary.IsReadOnly { get; }
member this.System.Collections.IDictionary.IsReadOnly : bool
 ReadOnly Property IsReadOnly As Boolean Implements IDictionary.IsReadOnly

Property Value


true if the IDictionary is read-only; otherwise, false. In the default implementation of SortedList<TKey,TValue>, this property always returns 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.
