Ruft eine ICollection ab, die die Werte in HybridDictionary enthält.

Assembly: System (in system.dll)
Syntax
'Declaration
Public ReadOnly Property Values As ICollection
'Usage
Dim instance As HybridDictionary
Dim value As ICollection
value = instance.Values
public ICollection Values { get; }
public:
virtual property ICollection^ Values {
ICollection^ get () sealed;
}
/** @property */
public final ICollection get_Values ()
public final function get Values () : ICollection
Eigenschaftenwert
Eine ICollection, die die Werte in HybridDictionary enthält.
Hinweise
Die Reihenfolge der Werte in ICollection ist nicht angegeben. Sie entspricht aber der Reihenfolge der entsprechenden Schlüssel in der von der Keys-Methode zurückgegebenen ICollection.
Die zurückgegebene ICollection ist keine statische Kopie, sondern die ICollection verweist zurück auf die Werte im ursprünglichen HybridDictionary. Änderungen am HybridDictionary werden daher auch in der ICollection wiedergegeben.
Das Abrufen des Werts dieser Eigenschaft ist eine O(1)-Operation.
Beispiel
Im folgenden Codebeispiel werden die Elemente von HybridDictionary aufgelistet.
