    {

        using (BinaryReader br = new BinaryReader(FileUpload1.PostedFile.InputStream))
        {
            byte[] bytes = br.ReadBytes((int)FileUpload1.PostedFile.InputStream.Length);
            string strConnString = ConfigurationManager.ConnectionStrings["CMSConnectionString"].ConnectionString;
            using (SqlConnection con = new SqlConnection(strConnString))
            {
                using (SqlCommand cmd = new SqlCommand())
                {
                    cmd.CommandText = "INSERT INTO tblComplaint(customerName, type, status,reply,Date,image) VALUES (@customerName, @type, @status,@reply,@Date,@audio)";
                    cmd.Parameters.AddWithValue("@customerName", TextBox1.Text);
                    cmd.Parameters.AddWithValue("@type", TextBox2.Text);

                    cmd.Connection = con;
                    con.Open();
                    cmd.ExecuteNonQuery();
