將報告呈現爲pdf

Question

我有一個將報告呈現爲pdf表單的c＃代碼。

  Random rand = new Random(); 
     num = rand.Next(1111, 999999); 
     Warning[] warnings; 
     string[] streamids; 
     string mimeType; 
     string encoding; 
     string extension; 
     String deviceInf = "<DeviceInfo><PageHeight>8.27in</PageHeight><PageWidth>11.69in</PageWidth><MarginTop>0in</MarginTop><MarginBottom>0in</MarginBottom><MarginLeft>0in</MarginLeft><MarginRight>0in</MarginRight></DeviceInfo>"; 
     byte[] bytes = reportViewer1.LocalReport.Render 
      (
      "PDF", deviceInf, out mimeType, out encoding, 
      out extension, 
      out streamids, out warnings); 

     var folderPath = "D:\\ICard\\STAFFPDF\\"; 
     if (!Directory.Exists(folderPath)) 
     { 
      Directory.CreateDirectory(folderPath); 
     } 

     FileStream fs = new FileStream(@"D:\ICard\STAFFPDF\" + num + ".pdf", FileMode.Create); 
     fs.Write(bytes, 0, bytes.Length); 
     this.reportViewer1.Refresh(); 
     fs.Close(); 

什麼，我試圖做的是保存PDF的鏡面形式，因爲PDF需要被打印成鏡像，有沒有什麼辦法，我可以做到這一點？

試試這段代碼。來源是here。

private string ExportReport() 
      { 
       Warning[] warnings; 
       string[] streamids; 
       string mimeType; 
       string encoding; 
       string filenameExtension; 


      ReportParameterInfoCollection pInfo = reportViewer1.ServerReport.GetParameters(); 
      string filenameParams = ""; 


      byte[] bytes; 
      if (reportViewer1.ProcessingMode == ProcessingMode.Local) 
      { 
       bytes = reportViewer1.LocalReport.Render("PDF", null, out mimeType, 
       out encoding, out filenameExtension, out streamids, out warnings); 
      } 
      else 
      { 
       bytes = reportViewer1.ServerReport.Render("PDF", null, out mimeType, 
       out encoding, out filenameExtension, out streamids, out warnings); 
      } 


      string filename = Path.Combine(Path.GetTempPath(), filenameParams + ".pdf"); 
      using (FileStream fs = new FileStream(filename, FileMode.Create)) 
      { fs.Write(bytes, 0, bytes.Length); } 


      return filename; 
     }
