{
cn.Open();
//Convert pdf in Binary formate
int lenght = FileUpload1.PostedFile.ContentLength;
byte[] data = new byte[lenght];
FileUpload1.PostedFile.InputStream.Read(data, 0, lenght);
using (SqlCommand cmd = new SqlCommand("insert into tblPdfData " + "(PdfData) values(@data)", cn))

using (SqlCommand cmd = new SqlCommand("select PDFData from tblpdfdata where ID='" + grvDisplayPdf.SelectedValue + "' ", cn))
{
using (SqlDataReader dr = cmd.ExecuteReader(System.Data.CommandBehavior.Default))
{
if (dr.Read())
{
// read in using GetValue and cast to byte array
byte[] fileData = (byte[])dr.GetValue(0);
// write bytes to disk as file
using (System.IO.FileStream fs = new System.IO.FileStream(sPathToSaveFileTo, System.IO.FileMode.Create, System.IO.FileAccess.ReadWrite))
{
// use a binary writer to write the bytes to disk
using (System.IO.BinaryWriter bw = new System.IO.BinaryWriter(fs))
{
bw.Write(fileData);
bw.Close();
}
}
}
// close reader to database
dr.Close();
}
}
}
