        [ValidateInput(false)]
        [HttpPost]
        public ActionResult DownloadPDF(string htmlContent)
        {
            //http://localhost/ZzsqmcZS/WebAPI/File/DownloadPDF?htmlContent=%3Cp%3E123132%3C/p%3E
            if (string.IsNullOrEmpty(htmlContent))
            {
                return null;
            }
            htmlContent = "<!DOCTYPE html><html lang=\"en\"xmlns=\"http://www.w3.org/1999/xhtml\"><style type=\"text/css\">*{margin:0;padding:0}body{font-family:'Microsoft YaHei','Microsoft YaHei UI',Tahoma,NSimsun,Simsun,\"\\5B8B\\4F53\",sans-serif;font-size:.28em;-webkit-text-size-adjust:none;overflow-x:hidden}html{overflow-y:scroll;height:100%;font-size:50px;-webkit-tap-highlight-color:transparent}.MsoNormal{letter-spacing: 0px;font-family:'Simsun';}</style><body>" + htmlContent + "</body></html>";
            var properties = new ConverterProperties();
            properties.SetCharset("utf-8");
            var provider = new DefaultFontProvider(true, true, true);// 第三个参数为True，以支持系统字体，否则不支持中文
            properties.SetFontProvider(provider); 

            var mediaDeviceDescription = new MediaDeviceDescription(MediaType.PRINT);// 指当前设备类型，如果是预览使用SCREEN 
            properties.SetMediaDeviceDescription(mediaDeviceDescription);

            string pdfPath = Server.MapPath("~/" + Guid.NewGuid() + ".pdf");
            using (var fileInfo = new FileStream(pdfPath, FileMode.Create))
            {
                HtmlConverter.ConvertToPdf(htmlContent, fileInfo, properties);
            }
            string fileName = PublicVars.SchoolName + "准考证.pdf";
            //方式1：
            //return File(pdfPath, "application/octet-stream", HttpUtility.UrlEncode(fileName));

            //方式2：
            var fileContent = new FileContentResult(System.IO.File.ReadAllBytes(pdfPath), "application/octet-stream");
            fileContent.FileDownloadName = Server.UrlEncode(fileName);
            //下载完成删除文件
            System.IO.File.Delete(pdfPath);
            return fileContent;
        }
