當pdf在瀏覽器中打開時提供打開/保存選項

Question

當我的用戶單擊鏈接時，我想爲PDF提供標準的打開/保存對話框，而不是在瀏覽器中打開它...使用ffg代碼生成PDF：

Document document = new Document(); 
     MemoryStream stream = new MemoryStream(); 
     try 
     { 
      PdfWriter pdfWriter = PdfWriter.GetInstance(document, stream); 
      pdfWriter.CloseStream = false; 

      document.Open(); 
      document.Add(new Paragraph("Hello World")); 
     } 
     catch (DocumentException de) 
     { 
      Console.Error.WriteLine(de.Message); 
     } 
     catch (IOException ioe) 
     { 
      Console.Error.WriteLine(ioe.Message); 
     } 

     document.Close(); 

     stream.Flush(); 
     stream.Position = 0; 
     return File(stream, "application/pdf"); 

Answer 1

嘗試使用File方法的第三個參數返回時，它提供一個名稱的文件：

return File(stream, "application/pdf", "report.pdf"); 

Answer 2

Document document = new Document(); 
    FileStream stream = new FileStream("report.pdf", FileMode.Create); 
    try 
    { 
     PdfWriter pdfWriter = PdfWriter.GetInstance(document, stream); 
     pdfWriter.CloseStream = false; 

     document.Open(); 
     document.Add(new Paragraph("Hello World")); 
    } 
    catch (DocumentException de) 
    { 
     Console.Error.WriteLine(de.Message); 
    } 
    catch (IOException ioe) 
    { 
     Console.Error.WriteLine(ioe.Message); 
    } 

    document.Close(); 

    stream.Flush(); 
    stream.Position = 0; 
    return File(stream, "application/pdf");
