{
    string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand())
        {
            cmd.CommandText = "SELECT Name, Data FROM tblFiles";
            cmd.Connection = con;
            con.Open();
            using (SqlDataReader sdr = cmd.ExecuteReader())
            {
                while (sdr.Read())
                {
                    byte[] bytes = (byte[])sdr["Data"];

                    string filePath = "~/Files/" + Path.GetFileName(sdr["Name"].ToString());
                    File.WriteAllBytes(Server.MapPath(filePath), bytes);
                }
