遇到的问题
在运行时，我总是得到以下信息NHibernate.MappingException：
"Could not compile the mapping document: GI.InventoryManager.CYB.Mappings.Part.hbm.xml"
是的，它的构建操作设置为Embedded Resource. InnerException 说：
"Could not find the dialect in the configuration"
要求（提供）的信息
这是我的配置文件，名为hibernate.cfg.xml：
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" >
<session-factory>
<property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
<property name="connection.connection_string">
Server=(local);initial catalog=GI_IM_CYB;Integrated Security=SSPI
</property>
<property name="adonet.batch_size">10</property>
<property name="show_sql">false</property>
<property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
<property name="use_outer_join">true</property>
<property name="command_timeout">60</property>
<property name="query.substitutions">true 1, false 0, yes 'Y', no 'N'</property>
<property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>
</session-factory>
</hibernate-configuration>
这实际上是Configuration_Templates文件夹中的复制粘贴，我只更改了以下信息：
Session Factory: "Removed the NHibernate.Test namespace and let the property for itself"
Dialect: "From MsSql2000Dialect To MsSql2005Dialect"
Connection_String: "I changed the Initial Catalog attribute to input my own database name"
Factory Class: "From LinFu to Castle"
这是我在代码中使用它的方式：
private void configBackgroundWorker_DoWork(object sender, DoWorkEventArgs e) {
Configuration c = new Configuration();
c.AddAssembly(typeof(Part).Assembly);
lock (_sessionFactory) {
_sessionFactory = c.BuildSessionFactory();
}
}

问题
我已经尝试将 dialect 属性放在配置的行上，但它都不起作用。
如何解决我遇到的这个方言问题？
