Questions on Configuration

1) I undestand that NHibernate retrieves connection in app.config under nhibernate section. If I would like to hide the connection string, is there a way to retrieve from another source ?

2) For the mapping info (hbm.xml), I can either suply the file or the assembly. Is there a way to supply memory stream ?


Thanks

Re #1:

You do not have to use an app.config file to configure NHibernate. I do all of my configuration "in code".

Assumes you have a static class with a private field _nhConfiguration of NHibernate.Cfg.Configuration and a private field _nhSessionFactory of NHibernate.ISessionFactory

Code:
_nhConfiguration = new NHibernate.Cfg.Configuration();
_nhConfiguration.Properties.Add("hibernate.connection.provider", "provider string");
_nhConfiguration.Properties.Add("hibernate.dialect", "dialect string");
_nhConfiguration.Properties.Add("hibernate.connection.connection_string", "your connection string");

//blah blah more properties...

_nhConfiguration.AddAssembly("your.dll"); //the dll that contains the .hbm.xml embeded resources.

_nhSessionFactory = _nhConfiguration.BuildSessionFactory();



I use the Nini configuration library to read xml configuration files with encrypted values.

Re #2:

If you have a memory stream of the hbm.xml, perhaps you could use the AddDocument method of the Configuration class. It takes an XmlDocument type, so maybe you could create one by loading the xml from your memory stream.

Never tried it, don't know if it would work, but that's my best guess.

Actually, there are lots 'n' lots of 'AddXxx()' methods and overloads on Configuration: AddXml(), AddXmlReader(), AddFile(), AddDirectory(), AddUrl() and, yes, AddInputStream(), which will load XML right from the Stream of your choice.

They really went nuts on configuration.
