Dictionary で、System.Collections.IDictionary インターフェイスの System.Collections.IDictionary.Values プロパティを使用して、ディクショナリの値を一覧表示する方法を次のコード例に示します。この例では、ディクショナリのキー/値ペアを列挙する方法も示します。System.Collections.IDictionary インターフェイスの列挙子が KeyValuePair オブジェクトではなく DictionaryEntry オブジェクトを返すことに注意してください。
次のコード例は、System.Collections.IDictionary.Add メソッドのトピックで取り上げている例および出力の一部分です。
