interop - Download excel file using memory stream in C#

Question

I have to return file by creating excel workbook from memory stream. I have used Interop, closed.xml, spire.xls but not founding a way to achieve the same.

    var stream=clsUploadHelper.GetAttachmentFileStream(string.Empty, Filename);
Workbook book=new Workbook();
book.worksheet.Add(stream);
                            stream.Position = 0;
                            string xmlString = "attachment;filename=" + Filename;
                            return File(stream, xmlString, Filename);

I am new in that, Please help if possible. Thanks in advance.
