2 mins read

PageCount property available under IBuiltInDocumentProperties shows the value only when the Excel document have the information of it. Otherwise, the default value will be returned.

The Excel document should first be converted to PDF to get the proper page count.

The following complete code snippet explains this.

C#

using (ExcelEngine excelEngine = new ExcelEngine())
{
    IApplication application = excelEngine.Excel;
    application.DefaultVersion = ExcelVersion.Excel2016;
    IWorkbook workbook = application.Workbooks.Open("../../Data/Template.xlsx");
    IWorksheet worksheet = workbook.Worksheets[0];
 
    ExcelToPdfConverter converter = new ExcelToPdfConverter(workbook);
    PdfDocument document = converter.Convert();
    document.Save("Output.pdf");
 
    PdfLoadedDocument loadedDocument = new PdfLoadedDocument("Output.pdf");
 
    //Get the page count
    int pageCount = loadedDocument.Pages.Count;
    loadedDocument.Close(true);
}

 

VB.NET

Using excelEngine As ExcelEngine = New ExcelEngine
    Dim application As IApplication = excelEngine.Excel
    application.DefaultVersion = ExcelVersion.Excel2016
    Dim workbook As IWorkbook = application.Workbooks.Open("../../Data/Template.xlsx")
    Dim worksheet As IWorksheet = workbook.Worksheets(0)
 
    Dim converter As ExcelToPdfConverter = New ExcelToPdfConverter(workbook)
    Dim document As PdfDocument = converter.Convert()
    document.Save("Output.pdf")
 
    Dim loadedDocument As PdfLoadedDocument = New PdfLoadedDocument("Output.pdf")
 
    'Get the page count
    Dim pageCount As Integer = loadedDocument.Pages.Count
    loadedDocument.Close(True)
End Using
