////第二种:使用FileStreamResult
//var fileStream = new MemoryStream(fileContents);
//return File(fileStream, "application/ms-excel", "fileStream.xls");
////第三种:使用FilePathResult
////服务器上首先必须要有这个Excel文件,然会通过Server.MapPath获取路径返回.
//var fileName = Server.MapPath("~/Files/fileName.xls");
//return File(fileName, "application/ms-excel", "fileName.xls");
