ActiveRecord 的类型初始值设定项引发异常

最近在研究ActiveRecord网上有很多贴子讲怎么用的。但自己照做就是出错。

最终定位在配置文件出错。应该是ActiveRecord有更新的原因。在国外的网站把配置复制了一份替换。问题解决了。我用的是castle.ActiveRecord + mysql 

<configSections>    
      <section name="activerecord" type="Castle.ActiveRecord.Framework.Config.ActiveRecordSectionHandler, Castle.ActiveRecord" />
</configSections>

<activerecord isWeb="true">
    <config>
      <add key="connection.driver_class" value="NHibernate.Driver.MySqlDataDriver" />
      <add key="dialect"                 value="NHibernate.Dialect.MySQLDialect" />
      <add key="connection.provider"     value="NHibernate.Connection.DriverConnectionProvider" />
      <add key="connection.connection_string" value="Database=test;Data Source=localhost;User Id=root;Password=root;" />
      <add key="proxyfactory.factory_class" value="NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle" />
      <add key="query.factory_class" value="NHibernate.Hql.Ast.ANTLR.ASTQueryTranslatorFactory, NHibernate" />
    </config>
  </activerecord>

这里还有关于连别的库的配置：
