Das folgende Codebeispiel zeigt, wie ein StringDictionary in ein Array kopiert werden kann.

CopyTo kopiert Objekte, die typecast sein können, in System.Collections.DictionaryEntry. DictionaryEntry enthält sowohl den Schlüssel als auch den Wert.

Die in die Array kopierten Elemente werden in derselben Reihenfolge sortiert, in der der Enumerator durchläuft StringDictionary.

Bei dieser Methode handelt es sich um einen O(n)-Vorgang, wobei n ist Count.
