Örnekler

Aşağıdaki kod örneği, IDictionary.Values System.Collections.IDictionary Dictionary<TKey,TValue> Sözlükteki değerlerini listelemek için, ile arabiriminin özelliğinin nasıl kullanılacağını gösterir.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. Örnek ayrıca sözlükte anahtar/değer çiftlerinin nasıl numaralandırılacağını gösterir; arabirim için numaralandırıcı System.Collections.IDictionary DictionaryEntry nesneler yerine nesneleri döndürdüğünü unutmayın KeyValuePair<TKey,TValue> .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.

Kod örneği, yöntemi için sağlanmış olan output dahil daha büyük bir örneğin bir parçasıdır IDictionary.Add .The code example is part of a larger example, including output, provided for the IDictionary.Add method.

Açıklamalar

Döndürülen değerlerin sırası ICollection belirtilmemiş, ancak özelliğin döndürdüğü karşılık gelen anahtarlarla aynı sırada olması garanti edilir ICollection Keys .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.

Bu özelliğin değerinin alınması bir O (1) işlemidir.Getting the value of this property is an O(1) operation.
