Report report1 = new Report();
            report1.Load(templatePath + "CTMR1.frx");
            report1.RegisterData(ds);
            ((PictureObject)report1.FindObject("Picture1")).ImageLocation = qrCodepath;
            //report1.Show();
            report1.Prepare();
 
            PDFExport export = new PDFExport();
            string tagertFolderUrl = Server.MapPath(Server.UrlDecode(Server.UrlDecode(@"/ReportFiles"))).TrimEnd('\\') + "\\";
            string tagertPathUrl = tagertFolderUrl + DateTime.Now.ToString("yyyyMMddHHmmss") + ".pdf";
            report1.Export(export, tagertPathUrl);
            System.Diagnostics.Process.Start(tagertPathUrl);
            report1.Dispose();
 注意点: System.Diagnostics.Process.Start(tagertPathUrl); 是打开pdf文件,即在本地启动AdobeReader,属于开启一个进程,但在服务器上无反应,因为客户端没有服务器的权限。
解决方法:return Json(Url.Content("/ReportFiles/" + reportName), JsonRequestBehavior.AllowGet);在浏览器中预览PDF,返回结果是ActionResult,其中路径要写位虚拟路径
 
 
二维码:
public string GetQRImage(string content)
        {
            string timeStr = DateTime.Now.ToFileTime().ToString();
            Bitmap bitmap = QRCodeEncoderContent(content);
            string filePath = Server.MapPath(Server.UrlDecode(Server.UrlDecode(@"/ReportFiles"))).TrimEnd('\\') + "\\" + "Images" + "\\";
            if (!Directory.Exists(filePath))
            {
                Directory.CreateDirectory(filePath);
            }
            bitmap.Save(filePath+timeStr + ".jpg");
            string getPath = filePath + timeStr + ".jpg";
            return getPath;
        }
      
        public Bitmap QRCodeEncoderContent(string content)
        {
            QRCodeEncoder qrCodeEncoder = new QRCodeEncoder();
            qrCodeEncoder.QRCodeVersion = 0;
            Bitmap bitmap = qrCodeEncoder.Encode(content, Encoding.UTF8);
            return bitmap;
        }
 
jquery实现二维码
引入jquery库文件
引入二维码js文件jquery.qrcode.min.js
js方法:
    $(function () {
        $("#erwei").qrcode("wwwwww");
    })
一个div:
   div id = "erwei"
注意,如果是mvc,需要在App_Start\BundleConfig.cs中解除绑定的其他js文件,否则会js冲突,报错:不支持qrcode属性或方法
