NHibernate 用法
错误：- The mapping for 'Model.GExam_DoctorAnswersEntity' was not added to the NHibernate configuration.
GExam_DoctorAnswers.hnm.xml文件：

<?xml version="1.0" encoding="utf-8" ?>

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Model" namespace="Model">

  <class name ="GExam_DoctorAnswersEntity,Model" table="GExam_DoctorAnswersEntity">

    <id name="C_AnsId" column="C_AnswerID" type="Int32" unsaved-value="0">

      <generator class ="native"></generator>

    <property name ="CA_DoctorAnswer" column="CA_DoctorAnswer" type="string" length="50" not-null="false"/>

  </class>

</hibernate-mapping>

bin文件下的hibernate.cfg.xml文件：

<?xml version="1.0" encoding="utf-8" ?>

<hibernate-configuration  xmlns="urn:nhibernate-configuration-2.2" >

  <session-factory >

    <!--<property name="connection.provider">NHibernate.Test.DebugConnectionProvider, NHibernate.Test</property>-->

</hibernate-configuration>

以上文件均设为嵌入的资源和始终复制，当调用  return _session.Get<GExam_DoctorAnswersEntity>(id);
会出现- The mapping for 'Model.GExam_DoctorAnswersEntity' was not added to the NHibernate configuration.错误



------解决方案--------------------
是不是你的GExam_DoctorAnswersEntity这个类的映射文件的名称问题，按道理会去取相同名称的xml，但是你却没有 而是有GExam_DoctorAnswers.hnm.xml 导致发生错误"The mapping for 'Model.GExam_DoctorAnswersEntity'
