NHibernate Without App.Config

Hey,
Is there a way to use NHibernate without an App.Config - configuring it with the nhibernate.cfg.xml file or doing it programmatically?
Thanks ahead

Yes, you can.
Try passing to the Configuration.Properties a hashtable with the values you want.
The keys & values should be the same as you've in the app.config.

The recommended way to set the properties programmatically is to use the const strings in the class NHibernate.Cfg.Environment and use the method Configuration.SetProperty().

eg:

Code:

cfg.SetProperty(NHibernate.Cfg.Environment.ConnectionString, "Server=(local);initial catalog=nhibernate;Integrated Security=SSPI");

To set the properties through a XML file, use the methods Configuration.Configure(...).

you can also pass the assembly with the cfg.xml file to the Configure operation of the Configuration object. Then add in your connection string dynamically.

Heres some sample code.

Code:

NH.Configuration sessionConfiguration = new NH.Configuration();
                  
//load up the assembly that contains the mappings file
AssemblyName libraryName = new AssemblyName();
libraryName.Name = this._configurationAssemblyName;
Assembly configurationAssembly = Assembly.Load(libraryName); 
                  
//configure the configuration with the specified configuration file 
sessionConfiguration.Configure(configurationAssembly, this._configurationResourceName);

//specify the connection string for the session factory - this could be done through configuration
//but we like to do this dynamically so we can encrypt it
sessionConfiguration.Properties.Add(NH.Environment.ConnectionString, this._connectionString);

First, thanks for all of your replys!
Second, jnapier - you write in your code snippet that I need to give the Configure method 2 parameters - the Assembly holding the hibernate.cfg.xml file, and the ResourceName - what do you mean by ResourceName?
Third, is there a different option instead of programmatically setting the properties of the Configuration object - i.e - to give it a path to an external configuration file?
Thanks again,

Ram

The ResourceName is the name of the xml file containing the configuration and which is embedded in your assembly; most of the time, it is something like MyAssembly.MyFile.xml. (you can use ILDAsm to see that name...)

You can call Configuration.Configure( string resource ) to use an external xml file...

Worked like a charm KPixel!
It would be nice to have one of the examples in the Quickstart use this method...
Thank you all for your help you'r doing great job!
