ListDictionary.CopyTo メソッド
アセンブリ: System (system.dll 内)

Dim instance As ListDictionary Dim array As Array Dim index As Integer instance.CopyTo(array, index)


要素は、列挙子が ListDictionary を反復処理するのと同じ順序で、Array にコピーされます。
ListDictionary 内のキーだけをコピーするには、ListDictionary.Keys.CopyTo を使用します。
ListDictionary 内の値だけをコピーするには、ListDictionary.Values.CopyTo を使用します。

ListDictionary の要素を配列にコピーするコード例を次に示します。
