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:

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

thanks in advance,

If you use a Pdf component (http://pdfapi.codeplex.com/), you can simply load byte array to PdfDocument object and save as a Pdf file.

PdfDocument doc = new PdfDocument();
doc.LoadFromBytes(byteArray);
doc.SaveToFile("output.pdf");

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();

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

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();

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

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)

Is there a way to pass server url to writeAllBytes method
like http://localhost:17813/QuadraSuiteWeb/PROPAttachments/PropertyBill.pdf. Because when I am trying add this url, an exception is coming "URI formats are not supported."

String _ReportPath = "Reports/PropertyManagement/PROPBillGeneration.rdlc";
PDFReportGenerator _PDFReportGenerator = new PDFReportGenerator(_ReportPath, "PROPBillReportDTO", P.PROPBillReportDTOList, Param);
var FileContent = _PDFReportGenerator.getReportBytes();

if (FileContent.Length > 0)
{
ReportDTO.PROPBillID = P.PROPBillID;
DefaultResponseDTO _DefaultResponseDTO = serviceUtil.GetServiceProxy<ipropbillgenerationservice>().GenerateBillAndSendMail(ReportDTO, FileContent);
string url = HttpContext.Current.Request.Url.AbsoluteUri.Replace(HttpContext.Current.Request.Url.AbsolutePath, "");
string siteFolder = "/" + HttpContext.Current.Request.FilePath.Split('/')[1];
url = url.Split('?')[0] + siteFolder + @"/PROPAttachments/PropertyBill.pdf";
url = url.Replace("~", "");
url = url.Replace("//", "/");
url = url.Insert(5, "/");
System.IO.File.WriteAllBytes(url, FileContent);
}
