i have access file by name song.mdb which has field by name file
where i am storing mp3 file in binary format .
when i tried to read the field into
ret byte array i am able to read only first 25 bytes .

Why am i not getting the full array which is 1024 bytes long

byte[] ret = new byte[2000];
OleDbCommand cmd = new OleDbCommand("select file from song", mycon);
            System.Data.OleDb.OleDbDataReader dr;
            dr = cmd.ExecuteReader();
            if (dr.Read())
                ret = (byte[])dr.GetValue(0);

private void button1_Click_1(object sender, EventArgs e)
            String strFileName;
            String str;

            OpenFileDialog dialog = new OpenFileDialog();

            dialog.InitialDirectory = "C:";
            dialog.Title = "Select a text file";
            if (dialog.ShowDialog() == DialogResult.OK)
                strFileName = dialog.FileName;

            //if strFileName == " ")
            //    return; //user didn't select a file to opena

            //insertsql = "insert into songs(ID,file) values(1,data)";
            str = dialog.FileName;

            FileStream fs = new FileStream(str, FileMode.Open);
            //int Size = 1024;
            byte[] data = new byte[100000];
            int b = fs.Read(data, 0, 100000);
            while (b != 0)
                b = fs.Read(data, 0, 100000);
            OleDbCommand cmd = new OleDbCommand("INSERT INTO song VALUES('1', '" + data + "')", mycon);

        private void button2_Click(object sender, EventArgs e)
