推荐答案

您希望编写一个HTTP处理程序来处理包含该对象的DB id的请求，并使用正确的标头返回该对象的字节。这已经在整个网络上被广泛报道，我确信这个网站上会有文章。你看了吗？

You want to write a HTTP Handler that handles requests that contain the DB id of the object, and returns the bytes of the object, with the right header. This has been covered ad nauseum all over the web, I am certain this site will have articles on it. Did you look ?

你可以将pdf文件转换成字节数组通过以下代码

Your can convert pdf file in to byte array By following code

byte[] array = new byte[file.ContentLength];
file.InputStream.Read(array, 0, array.Length);

通过以下代码，您可以重新检查文件

By following code you can recheck the file

System.IO.File.WriteAllBytes(@"c:\test.pdf", array);

很容易将字节数组存储到数据库中。

并且还读取字节数组并导出如下...

store the byte array to database easily.
and also read the byte array and export as follows ...

Response.Clear(); 
MemoryStream ms = new MemoryStream(pdfBytearray); 
Response.ContentType = "application/pdf"; 
Response.AddHeader("content-disposition", "attachment;filename=labtest.pdf"); 
Response.Buffer = true; 
ms.WriteTo(Response.OutputStream); 
Response.End();
