How to convert PDF document to byte array[] and byte array to PDF document

C#.NET : How to convert PDF document to byte array[] and byte array to PDF document

Converting a pdf document will be very helpful for you when you need totransfer PDF document over different remote applications. Use following method for it. Don't forget add reference to System.IO;

private byte[] StreamPDFToByte()
{
string filename = "C:\\sample.pdf";
FileStream fs = new FileStream(filename, FileMode.Open, FileAccess.Read);

// Create a byte array of file stream length
byte[] byteData = new byte[fs.Length];

//Read block of bytes from stream into the byte array
fs.Read(byteData, 0, System.Convert.ToInt32(fs.Length));

//Close the File Stream
fs.Close();
return byteData; //return the byte data
}

On the other hand you may need to convert the byte array into a PDF file back. So use following method.

private void StreamByteToPDF(byte[] byteData)
{
string filename = "C:\\Newsample.pdf";
FileStream fs = new FileStream(filename, FileMode.Create, FileAccess.Write);

//Read block of bytes from stream into the byte array
fs.Write(byteData, 0, byteData.Length);

//Close the File Stream
fs.Close();
}
