Aspose.Cellsは、Microsoft Excelの組み込み関数としてサポートされていないユーザー定義またはカスタム関数を実装するために使用されるAbstractCalculationEngineクラスを提供します。
この記事では、AbstractCalculationEngineから値の範囲を返す方法について説明します。
以下のコードはAbstractCalculationEngineの使用を示し、そのメソッドを介して値の範囲を返します。
関数CalculateCustomFunctionを持つクラスを作成します。このクラスはAbstractCalculationEngineを拡張します。
