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); 

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

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

thanks in advance,

Solution 1

You seem to be trying to write a byte arry from a database into a file: why is this giving you problems? If you have the bytes, just write them:
File.WriteAllBytes(@"C:\testpdf.pdf", myArrayOfBytes);
(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)

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

If it is a byte array, you can write it to disk so it becomes saved as *pdf file.
either, you can write the bytes to the response output stream and user will be prompt to download and save the file.

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

Can you please have a look at this code. I got it from the link given below.[^]

Hope this will help you.
