private void btnCSV_Click(object sender, System.EventArgs e)
{
      string fileName = "";
      string fileNameDel = "";
      string fileNameExt = "";
      CrystalDecisions.CrystalReports.Engine.ReportDocument report = new CrystalDecisions.CrystalReports.Engine.ReportDocument( );
      report = this.crystalReportViewer1.ReportSource as CrystalDecisions.CrystalReports.Engine.ReportDocument;
      if (report != null)
      {
            SaveFileDialog SDialog = new SaveFileDialog();
            SDialog.DefaultExt = "xls";
            if (SDialog.ShowDialog() == DialogResult.OK)
            {                    
                  report.ExportToDisk(ExportFormatType.Excel, SDialog.FileName);
                  fileName = SDialog.FileName;
                  fileNameDel = fileName;
                  fileNameExt = fileName;
            }

            Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
            excelApp.Visible = false;
            excelApp.DisplayAlerts = false;
            Microsoft.Office.Interop.Excel.Workbook excelWk = excelApp.Workbooks.Open(fileName,
                  Type.Missing, Type.Missing, Type.Missing, Type.Missing,
                  Type.Missing, Type.Missing, Type.Missing, Type.Missing,
                  Type.Missing, Type.Missing, Type.Missing, Type.Missing,
                  Type.Missing, Type.Missing);

            fileName = Path.ChangeExtension(fileName, ".csv");
            excelApp.ActiveWorkbook.SaveAs
                  (fileName, Microsoft.Office.Interop.Excel.XlFileFormat.xlCSVWindows,
                  Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,
                  Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
            excelApp.ActiveWorkbook.Save();
            excelApp.Quit();
            fileNameExt = Path.GetExtension(fileNameExt);

            if(fileNameExt == ".xls")
            {
                  File.Delete(fileNameDel);
            }
      }
