程序.cs

  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Text;
  using NHibernate;
  using NHibernate.Cfg;
 namespace Test
  {
   class Program
    {
      static void Main(string[] args)
       {           
        ISessionFactory factor = new Configuration().Configure().BuildSessionFactory();
        if(factor!=null){
            Console.WriteLine("Configured");
        }
        else{
            Console.WriteLine("Not Configured");
        }
        Student std = new Student { Fname = "James", Lname = "Bond", Address = "32 Baker Street", Institution = "MIT" };
        using (ISession session = factor.OpenSession()) 
        {
            using (ITransaction transaction= session.BeginTransaction())
            {
                try 
                { 
                session.Save(std);
                transaction.Commit();
                session.Close();

                }
                catch(Exception e)
                {
                    Console.WriteLine("ERROR :" + e);
                }
            }           
        }               
    }
    //protected ISessionFactory factory;


    protected void execute_query()
    {

    }
}

}

映射部分

学生.hbm.xml

  <?xml version="1.0" encoding="utf-8" ?>
      <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" auto-import="true">
      <class name="Test.Student" table="Info" lazy="true">
     <id name="Id" type="int" column="Id">
       <generator class="native" />
    </id>

       <property name="Fname" column ="Fname"/>
<property name="Lname" column="Lname"/>
<property name="Address" column="Address"/>
<property name="Institution" column="Institution"/>

<!-- We don't have to specify a column name if its the same 
     as the variable name -->

您需要add mapping assembly name在您的app.config文件中如此处所述。

   <property name="show_sql">false</property>
   <mapping assembly="Test"/>  <!-- Here -->
</session-factory>

还要确保将 XML 文件标记为Embedded Resource没有。
