EnterpriseLibrary数据访问应用程序块重定向部分无法找到默认数据库

我怎么能得到工作的数据重定向部分为EnterpriseLibrary数据访问应用程序块?

我想有数据库的定义从app.config删除，并放置在一个独立的数据库。配置文件。

我尝试用与日志记录相同的方式做。配置and和exception。配置文件，但我不能让它工作。

{
    class Program
    {
        static void Main(string[] args)
        {
            IConfigurationSource source = ConfigurationSourceFactory.Create();
            LogWriterFactory logwriterFactory = new LogWriterFactory(source);
            var logWriter = logwriterFactory.Create();
            Logger.SetLogWriter(logWriter);
            var exceptionPolicyFactory = new ExceptionPolicyFactory(source);
            var exceptionManager = exceptionPolicyFactory.CreateManager();
            ExceptionPolicy.SetExceptionManager(exceptionManager);
            DatabaseProviderFactory factory = new DatabaseProviderFactory(source);
            DatabaseFactory.SetDatabaseProviderFactory(factory, false);

            // Test Logging Block
            logWriter.Write("This a test");
            // Test Exception block
            try
            {
                throw new NotImplementedException();
            }
            catch (Exception exception)
            {
                Exception newException;
                var rethrowNewException = ExceptionPolicy.HandleException(exception, "Policy", out newException);
                if (rethrowNewException)
                    throw newException;
            }
            // Test Data Block fails with error code below
            //  System.InvalidOperationException was unhandled
            //  Message=The configuration file does not define a default database.
            var sqlServerDb = DatabaseFactory.CreateDatabase() as SqlDatabase;
            using (IDataReader reader = sqlServerDb.ExecuteReader(CommandType.Text, "SELECT TOP 1 * FROM Production.Product"))
            {
                while (reader.Read())
                {
                    for (int i = 0; i < reader.FieldCount; i++)
                    {
                        Console.WriteLine("{0} = {1}", reader.GetName(i), reader[i]);
                    }
                    Console.WriteLine("");
                }
            }
        }
    }
}
