引用：

从您的操作返回FileResult或FileStreamResult，具体取决于文件是否存在或您是否即时创建。

Return a FileResult or FileStreamResult from your action, depending on whether the file exists or you create it on the fly.

public ActionResult GetPdf(string filename)
{
    return File(filename, "application/pdf", Server.UrlEncode(filename));
}
