Using Aspose, this can be done easily!
public class XlsToPdf
{
public void ExportSheet()
{
///lets say we have an xls document containing 6 sheets
///each strongly named like sheet1 => sheet6
///suppose that you need to save sheet5 as a pdf document.
string sourceWorkBook = "source.xls";
string destinationDocument = "Destination.pdf";
Aspose.Cells.Workbook sourceWb = new Aspose.Cells.Workbook();
sourceWb.Open(sourceWorkBook);
foreach (Aspose.Cells.Worksheet workSheet in sourceWb.Worksheets)
{
if (!workSheet.Name.ToUpper().Contains("sheet5"))
workSheet.IsVisible = false;
}
///First thing to do is to save the xls in xml format,
///but the formattype used already refers to PDF
string destinationDocumentXml = "destination.xml";
sourceWb.Save(destinationDocumentXml,
Aspose.Cells.FileFormatType.AsposePdf);
Aspose.Pdf.Pdf pdfDocument = new Aspose.Pdf.Pdf();
//bind the created xml to the PDFDoc you intialized.
pdfDocument.BindXML(destinationDocumentXml, null);
//Save...
pdfDocument.Save(destinationDocument);
///If necessary, you can cleanup and remove
///the intermediate files created
///using DirectoryInfo and files delet techniques from the System.IO
///...code goes here
}
