如何从hibernate.cfg.xml文件获取连接字符串值？(How to get the connection string value from hibernate.cfg.xml file?)

 我使用Fluent NHibernate，并需要从hibernate.cfg.xml文件的connection.connection_string属性中获取我的连接字符串来创建我的Session Factory： 
 
private static ISessionFactory SessionFactory {
   get {
      return = Fluently.Configure()
         .Database(MySQLConfiguration.Standard.ConnectionString(c => c.FromConnectionStringWithKey("MyConnStr")))
         .Mappings(m => m.FluentMappings.AddFromAssemblyOf<FooMap>())
         .ExposeConfiguration(c => c.Properties.Add("hbm2ddl.keywords", "none"))
         .BuildSessionFactory();
   }
}
 
 我想从hibernate.cfg.xml文件中替换连接字符串的MyConnStr（即在我的web.config文件中）“ c => c.FromConnectionStringWithKey（”MyConnStr“） ”。 
 
 我试过使用NHibernate.Cfg.Environment.ConnectionString，但它没有工作。 
 
 我怎样才能得到这个？ 
 
 谢谢。 

I'm using Fluent NHibernate and need to get my Connection String from the connection.connection_string property on hibernate.cfg.xml file to create my Session Factory:
 
private static ISessionFactory SessionFactory {
   get {
      return = Fluently.Configure()
         .Database(MySQLConfiguration.Standard.ConnectionString(c => c.FromConnectionStringWithKey("MyConnStr")))
         .Mappings(m => m.FluentMappings.AddFromAssemblyOf<FooMap>())
         .ExposeConfiguration(c => c.Properties.Add("hbm2ddl.keywords", "none"))
         .BuildSessionFactory();
   }
}
 
I want to replace MyConnStr (that is in my web.config file) "c => c.FromConnectionStringWithKey("MyConnStr")" for the connection string from the hibernate.cfg.xml file.
 
I've tried use NHibernate.Cfg.Environment.ConnectionString, but it didn't work.
 
How can I get this?
 
Thank you.
