示例代码

//Source directory
  string sourceDir = RunExamples.Get_SourceDirectory();

  //Output directory
  string outputDir = RunExamples.Get_OutputDirectory();

  //Load source Excel file
  Workbook wb = new Workbook(sourceDir + "sampleRemoveExistingPrinterSettingsOfWorksheets.xlsx");

  //Get the sheet counts of the workbook
  int sheetCount = wb.Worksheets.Count;

  //Iterate all sheets
  for (int i = 0; i < sheetCount; i++)
  {
      //Access the i-th worksheet
      Worksheet ws = wb.Worksheets[i];

      //Access worksheet page setup
      PageSetup ps = ws.PageSetup;

      //Check if printer settings for this worksheet exist
      if (ps.PrinterSettings != null)
      {
          //Print the following message
          Console.WriteLine("PrinterSettings of this worksheet exist.");

          //Print sheet name and its paper size
          Console.WriteLine("Sheet Name: " + ws.Name);
          Console.WriteLine("Paper Size: " + ps.PaperSize);

          //Remove the printer settings by setting them null
          ps.PrinterSettings = null;
          Console.WriteLine("Printer settings of this worksheet are now removed by setting it null.");
          Console.WriteLine("");
      }//if
  }//for
