Castle ActiveRecord配置文件中连接字符串解密

使用Castle ActiveRecord通常都是使用配置文件进行数据库连接配置。然后采用如下方式初始化：

IConfigurationSource source = ConfigurationManager.GetSection("activerecord") as IConfigurationSource;
ActiveRecordStarter.Initialize(Assembly.Load("ORM.Model"), source);

但是如果采用加密的数据库连接字符串如何进行解密呢？
通过反编译可发现source的children继承了MutableConfiguration类，MutableConfiguration类的Value并非是只读属性，因此可以通过如下方法进行实现加密连接字符串的解密。

IEncryption encrytion = new RSAEncryption();
IConfigurationSource source = ConfigurationManager.GetSection("activerecord") as IConfigurationSource;
MutableConfiguration connectionValue = source.GetConfiguration(typeof(ActiveRecordBase)).Children["connection.connection_string"] as MutableConfiguration;
connectionValue.Value = encrytion.Decrypt(connectionValue.Value);
ActiveRecordStarter.Initialize(Assembly.Load("ORM.Model"), source);

经过测试，字符串已解密成正常的连接字符串。
