saving email attachments as binary to the database using c# - email

Question

I can get email attachments from exchange server 2003 (MAPI.Attachment). How can I save the pdf attachment file as binary into the database?
Here's some code to understand better. For testing purposes I am saving the attachment pdf file into a filesystem. How ca I go about saving that into a database? Or how can I convert that into a byte array? Also, how can I get the size of the file since I need that when I declare the byte array "fileData"...
byte[] fileData = new byte[10000];
string[] fileTokens = new string[2];
string[] result = new string[3];
message.Unread = false;
emailSubject = message.Subject.ToString();
emailBody = message.Text.ToString();
MAPI.Attachments test = null;
test = (MAPI.Attachments)message.Attachments;
int attachmentCount = (int)test.Count;
for (int loopCounter = 1; loopCounter <= attachmentCount; loopCounter++)
{
MAPI.Attachment test2 = (MAPI.Attachment)test.get_Item(loopCounter);
bool temp = (test2.Name.ToString().Contains(".pdf") && test2.Name.ToString().IndexOf('Q') == 0);
if (test2.Name.ToString().Contains(".pdf") && test2.Name.ToString().IndexOf('Q') == 0)
{
//test2.ReadFromFile(fileData);
test2.WriteToFile("d:\\data\\" + test2.Name);
PDFParser pdfParser = new PDFParser();
pdfParser.ReadPdfFile("d:\\data\\" + test2.Name, result);
sentTime = (DateTime)message.TimeSent;
string fileName = (string)test2.Name;
fileTokens = fileName.Split('.');
}
RequestHistorySet historySet = new RequestHistorySet(1, sentTime, fileData, fileTokens[1]);
bool res = historySet.Update();
message.Unread = false;
message.Update();
And here's the Update function from historySet Class
public bool Update()
{
using (SqlConnection mySqlConnection = ...))
{
// Set up the Command object
SqlCommand myCommand = new SqlCommand("CONNECTION STRING..", mySqlConnection);
// Set up the OriginalName parameter
SqlParameter prmId = new SqlParameter("#id", SqlDbType.Int);
prmId.Value = id;
myCommand.Parameters.Add(prmId);
SqlParameter prmRequsetDate = new SqlParameter("#requestDate", SqlDbType.DateTime);
prmRequsetDate.Value = requestDate;
myCommand.Parameters.Add(prmRequsetDate);
// Set up the FileData parameter
SqlParameter prmFileData = new SqlParameter("#uplodedQuote_File ", SqlDbType.VarBinary);
prmFileData.Value = fileData;
prmFileData.Size = fileData.Length;
myCommand.Parameters.Add(prmFileData);
SqlParameter prmFileExtension = new SqlParameter("#uplodedQuote_Ext", SqlDbType.NVarChar);
prmFileExtension.Value = fileExtension;
myCommand.Parameters.Add(prmFileExtension);
// Execute the command, and clean up.
mySqlConnection.Open();
bool result = myCommand.ExecuteNonQuery() > 0;
mySqlConnection.Close();
return result;
}
}

As of now this is what I have done. I save it to a filesystem and then read from there.
test2.WriteToFile("d:\\data\\" + test2.Name);
fileData = FileToByteArray("d:\\data\\" + test2.Name);
PDFParser pdfParser = new PDFParser();
pdfParser.ReadPdfFile("d:\\data\\" + test2.Name, result);
TryToDelete("d:\\data\\" + test2.Name);
sentTime = (DateTime)message.TimeSent;
string fileName = (string)test2.Name;
fileTokens = fileName.Split('.');
historySet = new RequestHistorySet(1, sentTime, fileData, fileTokens[1]);
