It looks like rptObject is a Stream

You can just use CopyTo in that case

var oStream = new MemoryStream();
Stream stream = null;

if (rptName == "rpt_BankFormatExCopy.rpt" | rptName == "GIS_reportExFormat.rpt" | rptName == "GPFDeductionRepExFormat.rpt")
    stream = rptObject.ExportToStream(CrystalDecisions.Shared.ExportFormatType.ExcelRecord);
else
    stream = rptObject.ExportToStream(CrystalDecisions.Shared.ExportFormatType.Excel);

stream.CopyTo(oStream);
