Private ReadOnly Property IsReadOnly As Boolean
    Implements ICollection(Of KeyValuePair(Of TKey, TValue)).IsReadOnly

Dim instance As Dictionary
Dim value As Boolean

value = CType(instance, ICollection(Of KeyValuePair(Of TKey, TValue))).IsReadOnly

bool ICollection<KeyValuePair<TKey, TValue>>.IsReadOnly { get; }

private:
virtual property bool IsReadOnly {

J# supports the use of explicit interface implementations, but not the declaration of new ones.

JScript does not support explicit interface implementations.

Property Value

true if the ICollection<(Of <(T>)>) is read-only; otherwise, false. In the default implementation of Dictionary<(Of <(TKey, TValue>)>), this property always returns false.

Implements

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.

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