        connStrCnt.ToString();

    // Get the configuration file.
    System.Configuration.Configuration config =
        ConfigurationManager.OpenExeConfiguration(
        ConfigurationUserLevel.None);

    // Add the connection string.
    ConnectionStringsSection csSection =
        config.ConnectionStrings;

        new ConnectionStringSettings(csName,
            "LocalSqlServer: data source=127.0.0.1;Integrated Security=SSPI;" +
            "Initial Catalog=aspnetdb", "System.Data.SqlClient"));
