求解:Nhibernate Unknown entity class 的解决办法

概述:

     当运行 session.Save(tnp);时,出现这个"Unknown entity class: TestCleanSnow.TestNhibernatePerson"这个异常.

     映射文件 TestNhibernatePerson.hbm.xml如下:  

<?xml version="1.0" encoding="utf-8"?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="TestCleanSnow" namespace="TestCleanSnow">
  <class name="TestCleanSnow.TestNhibernatePerson,TestCleanSnow" table="TEST_NHIBERNATE_PERSON" lazy="false">
    <id name="Usertestid" column="USERTESTID" type="Decimal">
      <generator class="sequence">
        <param name="sequence">emp_sequence</param>
      </generator>
    </id>
    <property type="string" not-null="true" length="6" name="Usertestname" column="USERTESTNAME" />
  </class>
</hibernate-mapping>

 操作代码如下:

 

 Configuration config = new Configuration();              
                ISessionFactory factory = config.BuildSessionFactory();
                ISession session = factory.OpenSession();

                TestNhibernatePerson tnp = new TestNhibernatePerson();
 tnp.Usertestname = "test4";
  ITransaction trans = session.BeginTransaction();
           try
           {
             
               // 保存记录
               session.Save(tnp);
               trans.Commit();
               Console.WriteLine("Insert Success!");

                                          
           }
           catch (Exception ex)
           {
               trans.Rollback();
               Console.WriteLine(ex.Message);
           }

           finally
           {
               session.Close();
           }

  配置代码app.config如下: 

<configuration>
  <!-- Add this element -->
  <configSections>
    <section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" />
    <!--<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />-->
  </configSections>
  <!-- Add this element -->
  <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"  >

    <session-factory>
      <property name="dialect">NHibernate.Dialect.OracleDialect</property>
      <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
      <property name="connection.connection_string">user id=jkpt;data source=jkorasvr;password=designer;</property>
      <property name="connection.isolation" >ReadCommitted</property>
      <property name="show_sql">true</property>
      <!-- mapping files -->
      <mapping assembly="TestCleanSnow" />
    </session-factory>
  </hibernate-configuration>

说明:在操作代码中加载相应引用后 config.AddAssembly("TestCleanSnow");,就不出现错误.

如果以配置文件的形式加载引用却出现如题的错误.

解决方法1:

   可能是相应的映射文件没有设置成"嵌入式资源".我这里相应的映射文件为 TestNhibernatePerson.hbm.xml.

   在解决方案资源管理器中找到TestNhibernatePerson.hbm.xml该映射文件

   右击---属性----在将“生成操作”设置成“嵌入的资源”.

 解决方法1我已经设置成"嵌入入的资源",但还是出现如题的错误,请问哪位大侠已经解决了,给予指示.
