Örnekler

Aşağıdaki kod örneği, sözlükteki IDictionary.Values değerleri listelemek için ile arabiriminin System.Collections.IDictionaryDictionary<TKey,TValue>özelliğinin nasıl kullanılacağını gösterir. Örnekte ayrıca sözlükteki anahtar/değer çiftlerinin nasıl numaralandırılası da gösterilmektedir; Arabirimin numaralandırıcısının System.Collections.IDictionary nesneler yerine KeyValuePair<TKey,TValue> nesneler döndürdüğünü DictionaryEntry unutmayın.
