Excel.Workbook.SaveAs(...) with a same name file

Question

I'm working with xls file. How can I save it (if exist) with the same file name + "(copy 1)" like Windows desktop.

method saveCommande(...)

        if(!Directory.Exists(System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "EE_Commande_Fournisseur"))
        {
            Directory.CreateDirectory(System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\EE_Commande_Fournisseur");
        }
        xlWorkBook.SaveAs("EE_Commande_Fournisseur\\" + path, Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, true, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
        path = System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\EE_Commande_Fournisseur\\" + path;

        xlWorkBook.Close(true, misValue, misValue);
        xlApp.Quit();
        this.ReleaseComObject(xlApp,xlWorkBook);
        //sauvergarde dans la base de données
        _newAchatCommande.path = path;
        this._fileName = path;
        contexte.AddToAchatCommande(_newAchatCommande);
        contexte.SaveChanges();

thanks

Solution

try using File object's Exists method:

  if (!System.IO.File.Exists(@"C:\test2.xls"))
  {
   xlWorkBook.SaveAs(@"c:\test2.xls"); 
  }
  else
  {

   xlWorkBook.SaveAs(@"c:\test2(Copy).xls"); 

  }  

Or Alternatively you can overwrite your excel file by

   Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();

  excel.DisplayAlerts = false;

  excelSheePrint.SaveAs(filename, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookDefault, Type.Missing, Type.Missing, true, false, XlSaveAsAccessMode.xlNoChange, XlSaveConflictResolution.xlLocalSessionChanges, Type.Missing, Type.Missing);

Note: It will overwrite the existing excel (if exist) without asking the user.

What if I want to save data in the same excel file for a number of iterations (without overwriting the existing data) ?
