 string attachment = "attachment; filename=myfile.csv";  httpcontext.current.response.clear();  httpcontext.current.response.clearheaders();  httpcontext.current.response.clearcontent();  httpcontext.current.response.addheader("content-disposition", attachment);  httpcontext.current.response.contenttype = "text/csv";  httpcontext.current.response.addheader("pragma", "public");  // logic goes here write file.  // want copy above file file.   string filepath = server.mappath("~/exportedfiles/") +"newfile.csv";  var excelfile = file.create(filepath);  excelfile.close();  httpcontext.current.response.transmitfile(filepath);  httpcontext.current.response.flush();
