Syntax

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

bool ICollection<TValue>.IsReadOnly { get; }

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

A collection that is read-only does not allow the addition, removal, or modification of elements after the collection is created.

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