Příklady

Následující příklad kódu ukazuje, jak použít IDictionary.Values vlastnost System.Collections.IDictionary rozhraní s a Dictionary<TKey,TValue>, chcete-li vypsat hodnoty ve slovníku.The following code example shows how to use the IDictionary.Values property of the System.Collections.IDictionary interface with a Dictionary<TKey,TValue>, to list the values in the dictionary. Příklad také ukazuje, jak vytvořit výčet párů klíč/hodnota ve slovníku; Všimněte si, že enumerátor pro System.Collections.IDictionary rozhraní vrací DictionaryEntry objekty spíše než KeyValuePair<TKey,TValue> objekty.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.

Příklad kódu je součástí většího příkladu, včetně výstupu, poskytnutého pro IDictionary.Add metodu.The code example is part of a larger example, including output, provided for the IDictionary.Add method.

Poznámky

Pořadí hodnot ve vrácených ICollection hodnotách není určeno, ale je zaručeno, že bude stejné pořadí jako odpovídající klíče ICollection ve vrácené Keys vlastnosti.The order of the values in the returned ICollection is unspecified, but it is guaranteed to be the same order as the corresponding keys in the ICollection returned by the Keys property.

Získání hodnoty této vlastnosti je operace O (1).Getting the value of this property is an O(1) operation.
