Eine Excel-Formel ist ein Ausdruck, der mit einem Gleichheitszeichen (=) beginnt und für mathematische Berechnungen, Datenmanipulation und die Ableitung von Ergebnissen basierend auf den Zellwerten verwendet wird. Sie kann Arithmetik, Funktionen, Zellbezüge, Konstanten und logische Operationen enthalten. Formeln ermöglichen dynamische Aktualisierungen bei sich ändernden Zellwerten und machen Excel zu einem vielseitigen Werkzeug für die Automatisierung von Aufgaben und die Datenanalyse.

IronXL unterstützt die Bearbeitung bestehender Formeln in einer Excel-Datei, die Abfrage des Ergebnisses der Formel und die Erzwingung einer Neuauswertung der Arbeitsmappe. Dadurch wird sichergestellt, dass jede Formel für genaue Ergebnisse neu berechnet wird. IronXL unterstützt über 165 Formeln.

Formeln bearbeiten Beispiel

Um die Formel zu bearbeiten oder festzulegen, greifen Sie auf die Formula-Eigenschaft zu. Wählen Sie zunächst einen Bereich oder eine Zelle aus, und rufen Sie dann die Eigenschaft Formel auf und legen Sie sie fest. Die Eigenschaft Formula ist sowohl eine Get- als auch eine Set-Eigenschaft, die die Formelzeichenfolge zurückgibt, falls vorhanden. Rufen Sie die EvaluateAll-Methode auf, um das gesamte Arbeitsbuch neu zu bewerten und genaue Berechnungen sicherzustellen.

using IronXL;

// Load workbook
WorkBook workBook = WorkBook.Load("Book1.xlsx");

// Select worksheet

// Edit or Set formula
workSheet["A4"].Formula = "=SUM(A1,A3)";

// Reevaluate the entire workbook

Ergebnis aus Formel abrufen

Obwohl es manchmal anwendbar ist, das Ergebnis aus der Value-Eigenschaft des ausgewählten Bereichs und der Zelle abzurufen, wird empfohlen, das Ergebnis aus der FormattedCellValue-Eigenschaft der Zelle abzurufen, um ein genaueres Ergebnis der Formel zu erhalten. In dem ausgewählten Bereich können Sie auf die Zelle zugreifen, indem Sie die First-Methode aufrufen. Mit dieser Methode wird das erste Element der Liste ausgewählt, in unserem Fall die Zelle "A4" Von dort aus können Sie auf die Eigenschaft "FormattedCellValue" zugreifen.
