Values

Příklady

Následující příklad kódu ukazuje, jak použít IDictionary.Values vlastnost System.Collections.IDictionary rozhraní s SortedList<TKey,TValue>, k výpisu hodnot v seřazený seznam. Příklad také ukazuje, jak vytvořit výčet párů klíč/hodnota v seřazený seznam; Všimněte si, že enumerátor pro System.Collections.IDictionary rozhraní vrací DictionaryEntry objekty spíše než KeyValuePair<TKey,TValue> objekty.

Příklad kódu je součástí většího příkladu, včetně výstupu poskytnutého pro metodu IDictionary.Add .

Poznámky

Pořadí hodnot v souboru ICollection je stejné jako pořadí v SortedList<TKey,TValue>.

Načtení hodnoty této vlastnosti je operace O(1).
