I am trying to return a byte array from my MVC project controller to an html view. So far I haven't had any luck with trying to use FileStreamResult, due to Type System.Web.Mvc.FileStreamResult cannot be serialized. How can I return the byte array from my Controller to a View so that I can download a file?

Try this: [HttpGet] public FilePathResult DownloadTemplate() { return this.File(Path.Combine(this.excelTemplateFolder, this.excelTemplateFileName), "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"); } – Bhasyakarulu Kottakota Jul 24 '14 at 16:22
