                        Byte[] fileContent = manager.GetRiskReportByte(format, orgRecNos, noPendingProposals, isPendingProposals, isDisapprovedProposals, dateFrom, dateTo, minRiskScore, maxRiskScore, dataOnlyValue, riskScoreRecNos, isUnassessed, orderByParam, orderByFlow, isAllRisk);

DON'T SHOUT. Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalisation if you want to be taken seriously.

Check the file name! You want to open RiskReport.xls, but in code you are trying to open RiskReportxl.xls. Do you see the difference?

thaks sir.
but is does not working same error is appear. when ever i am usng /*theWorkbook.SaveCopyAs(fileName);
theWorkbook.Close(false, fileName, true);
byte[] data = ExportImportUtil.StreamFile(fileName);
File.Delete(fileName);*/

instead of byte[] data = new System.Text.ASCIIEncoding().GetBytes(theWorkbook.ToString());

then there is no error .
