问题描述

亲爱的所有人，

我需要一些帮助才能将字节数组来自DataBase转换为pdf。有人能给我一个C＃中的例子吗？以下是我到目前为止使用System.IO的

Dear All,

I need some help in converting a byte array "Which Came From DataBase" to pdf. Could someone give me an example of how in C#? Here is what I have so far,

using System.IO;

string sFile = "c:\testpdf.pdf"; //Path
FileStream fs = File.Create(sFile);
BinaryWriter bw = new BinaryWriter(fs);

我用这个将Pdf文件转换成字节数组：

And I have Used This To Convert The Pdf File Into Byte Array:

FileUpload1.SaveAs(filePathName);
byte[] picArray= System.IO.File.ReadAllBytes(filePathName);

提前感谢，

thanks in advance,

推荐答案

File.WriteAllBytes(@"C:\testpdf.pdf", myArrayOfBytes);

（您应该知道这可能会失败 - 权限问题通常会阻止写入HDD的根目录 - 请尝试使用子目录）

(You should be aware that this is likely to fail - permissions problems often prevent writes to the root directory of a HDD - try using a subdirectory instead)

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();

Response.Clear();
Response.ContentType = "application/pdf";
Response.AppendHeader("Content-Disposition", "inline;filename=data.pdf");
Response.BufferOutput = true;
byte[] pdf;
Response.AddHeader("Content-Length", response.Length.ToString());
Response.BinaryWrite(pdf);
Response.End();

您能否看一下这段代码。我从下面给出的链接中得到了它。
