Cerca dati utilizzando valori originali

Il seguente codice di esempio illustra il punto sopra. Trova la cella D4 che non può essere trovata utilizzando le opzioni di ricerca di Microsoft Excel ma Aspose.Cells può trovarla utilizzando LookInType.OriginalValues. Si prega di leggere i commenti all’interno del codice per ulteriori informazioni.

Output della console generato dall’esempio di codice

  

Aspose.Cells.Cell [ D4; ValueType : IsNumeric; Value : ---; Formula:=SUM(A1:A2)]
Verifica se il valore della cella inizia con un apice singolo
