SortedDictionary<TKey,TValue>.IDictionary.Values Eigenschaft

Definition

Ruft eine ICollection ab, die die Werte im IDictionary enthält.Gets an ICollection containing the values in the IDictionary.

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

Eigenschaftswert

Eine ICollection, die die Werte im IDictionary enthält.An ICollection containing the values in the IDictionary.

Beispiele

Im folgenden Codebeispiel wird gezeigt, wie die IDictionary.Values-Eigenschaft der System.Collections.IDictionary-Schnittstelle mit einem SortedDictionary<TKey,TValue>verwendet wird, um die Werte im Wörterbuch aufzulisten.The following code example shows how to use the IDictionary.Values property of the System.Collections.IDictionary interface with a SortedDictionary<TKey,TValue>, to list the values in the dictionary. Das Beispiel zeigt auch, wie die Schlüssel-Wert-Paare im Wörterbuch aufgelistet werden. Beachten Sie, dass der Enumerator für die System.Collections.IDictionary-Schnittstelle DictionaryEntry Objekte anstelle von KeyValuePair<TKey,TValue> Objekten zurückgibt.The example also shows how to enumerate the key/value pairs in the dictionary; note that the enumerator for the System.Collections.IDictionary interface returns DictionaryEntry objects rather than KeyValuePair<TKey,TValue> objects.

Das Codebeispiel ist Teil eines größeren Beispiels, einschließlich der Ausgabe, die für die IDictionary.Add-Methode bereitgestellt wird.The code example is part of a larger example, including output, provided for the IDictionary.Add method.

Hinweise

Die Werte in der zurückgegebenen ICollection werden nach der Comparer-Eigenschaft sortiert und sind garantiert in derselben Reihenfolge wie die entsprechenden Schlüssel in der ICollection, die von der Keys-Eigenschaft zurückgegeben werden.The values in the returned ICollection are sorted according to the Comparer property, and are guaranteed to be in the same order as the corresponding keys in the ICollection returned by the Keys property.

Das Abrufen des Werts dieser Eigenschaft ist ein O (1)-Vorgang.Getting the value of this property is an O(1) operation.
