Filestream System.OutofmemoryException

[sharon.chapman7@gmail.com]

Hi,
I am getting an System.OutofmemoryException when using Filestream to load zip file. the file is 521MB. My code is:

//Insert using Filestream, file into SQL Server Table
private void btnInsert_Click(object sender, EventArgs e)
{
OpenFileDialog openFileDlg = new OpenFileDialog();
openFileDlg.InitialDirectory = Directory.GetCurrentDirectory();
if (openFileDlg.ShowDialog() == DialogResult.OK)
{
FileInfo fi = new FileInfo(openFileDlg.FileName);
FileStream fs = new FileStream(fi.FullName, FileMode.Open, FileAccess.Read);
BinaryReader rdr = new BinaryReader(fs);
byte[] fileData = rdr.ReadBytes((int)fs.Length);
rdr.Close();
fs.Close();

My program dies on this line: byte[] fileData = rdr.ReadBytes((int)fs.Length);
i have also attached the detail for the System.OutofMemoryException. I am runing this on a Windows 7, 64bit machine.

thanks for your help.
