  3.             // var bytes = s;  
  4.   
  5.   
  6.             byte[] bytes = Convert.FromBase64String(s);  
  7.               Image image1;  
  8.             try  
  9.             {  
  10.                   using (var ms = new MemoryStream(bytes, 0, bytes.Length))  
  11.   
  12.                 {  
  13.   
  14.                     ms.Seek(0, SeekOrigin.Begin);  
  15.                     ms.Position = 0;  
  16.

  20.                       
  21.                     using (Image imageFile = image1)

  23.                         FrameDimension frameDimensions = new FrameDimension(  
  24.                             imageFile.FrameDimensionsList[0]);  
  25.   
  26.                         int frameNum = imageFile.GetFrameCount(frameDimensions);  
  27.                         string[] jpegPaths = new string[frameNum];  
  28.                         PdfDocument doc = new PdfDocument();  
  29.                         for (int frame = 0; frame < frameNum; frame++)  
  30.                         {  
  31.                             imageFile.SelectActiveFrame(frameDimensions, frame);  
  32.                             doc.Pages.Add(new PdfPage());  
  33.                             XGraphics xgr = XGraphics.FromPdfPage(doc.Pages[frame]);  
  34.                             using (Bitmap bmp = new Bitmap(imageFile))  
  35.                             {  
  36.                                 using (var ms11 = new MemoryStream())  
  37.                                 {  
  38.                                     bmp.Save(ms11, System.Drawing.Imaging.ImageFormat.Png);  
  39.                                     XImage img = XImage.FromStream(ms11);  
  40.   
  41.                                     PdfPage page = new PdfPage();  
  42.   
  43.                                     xgr.DrawImage(img, 0, 0, 595, 842);  
  44.                                 }

  50.                         {  
  51.                             doc.Save(stream, true);  
  52.                             fileContents = stream.ToArray();  
  53.                         }  
  54.   
  55.                         TempData["file"] = Convert.ToBase64String(fileContents);  
  56.                         doc.Close();  
  57.
