SortedDictionary<TKey,TValue>.IDictionary.Values Eigenschap

property System::Collections::ICollection ^ System::Collections::IDictionary::Values { System::Collections::ICollection ^ get(); };

System.Collections.ICollection System.Collections.IDictionary.Values { get; }

member this.System.Collections.IDictionary.Values : System.Collections.ICollection

 ReadOnly Property Values As ICollection Implements IDictionary.Values

Waarde van eigenschap

Een ICollection met de waarden in de IDictionary.

Implementeringen

Voorbeelden

In het volgende codevoorbeeld ziet u hoe u de IDictionary.Values eigenschap van de System.Collections.IDictionary interface gebruikt met een SortedDictionary<TKey,TValue>, om de waarden in de woordenlijst weer te geven. In het voorbeeld ziet u ook hoe u de sleutel-/waardeparen in de woordenlijst opsommen; Houd er rekening mee dat de enumerator voor de System.Collections.IDictionary interface objecten retourneert DictionaryEntry in plaats KeyValuePair<TKey,TValue> van objecten.

Het codevoorbeeld maakt deel uit van een groter voorbeeld, inclusief uitvoer, dat is opgegeven voor de IDictionary.Add methode.

Opmerkingen

De waarden in de geretourneerde ICollection waarde worden gesorteerd op basis van de Comparer eigenschap en zijn gegarandeerd in dezelfde volgorde als de bijbehorende sleutels in de ICollection geretourneerde Keys eigenschap.

Het ophalen van de waarde van deze eigenschap is een O(1)-bewerking.
