废话不多说，直接上图：
这是整个项目的目录结构。
其中：User.cs代码如下：
using System;
using System.Collections;
namespace Modelse
{
#region User
/// <summary>
/// User object for NHibernate mapped table 'user'.
/// </summary>
public class User
{
#region Member Variables
protected int id;
protected string uname;
#endregion
#region Constructors
public User() { }
public User( string uname )
{
this.uname = uname;
}
#endregion
#region Public Properties
public int Id
{
get {return id;}
set {id = value;}
}
public string Uname
{
get { return uname; }
set
{
if ( value != null && value.Length > 11)
throw new ArgumentOutOfRangeException("Invalid value for Uname", value, value.ToString());
uname = value;
}
}
#endregion
}
#endregion
}
User.xml的代码如下:
<?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Models" namespace="Models"> <class name="User" entity-name="User"> <id name="Id" type="Int32" unsaved-value="0"> <column name="id" sql-type="int" not-null="true" unique="true" index="PRIMARY"/> <generator class="native" /> </id> <property name="Uname" type="String"> <column name="uname" length="11" sql-type="varchar" not-null="true"/> </property> </class> </hibernate-mapping>
hibernate.cfg.xml的代码如下：
<?xml version="1.0" encoding="utf-8"?>
<!--
This template was written to work with NHibernate.Test.
Copy the template to your NHibernate.Test project folder and rename it in hibernate.cfg.xml and change it
for your own use before compile tests in VisualStudio.
-->
<!-- This is the ByteFX.Data.dll provider for MySql -->
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" >
<session-factory name="NHibernate.Test">
<property name="connection.driver_class">NHibernate.Driver.MySqlDataDriver</property>
<property name="connection.connection_string">
server=localhost;database=mytxt;uid=root;pwd=root;
</property>
<property name="dialect">NHibernate.Dialect.MySQLDialect</property>
<property name="proxyfactory.factory_class">NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property>
<mapping assembly="Models"/>
</session-factory>
</hibernate-configuration>
NHibernateHelper.cs的代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using NHibernate.Cfg;
using NHibernate;
namespace DAL
{
public class NHibernateHelper
{
private ISessionFactory _sessionFactory;
public NHibernateHelper()
{
_sessionFactory = GetSessionFactory();
}
private ISessionFactory GetSessionFactory()
{
return (new Configuration()).Configure("hibernate.cfg.xml").BuildSessionFactory();
}
public ISession GetSession()
{
return _sessionFactory.OpenSession();
}
}
}
Helper.cs的代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using NHibernate;
using NHibernate.Cfg;
using NHibernate.Cfg.Loquacious;

public HbmMapping getMapping()

var mapper = new Mapper(orm);
return mapper.CompileMappingFor(new[] { typeof(User) });
}
public Configuration getConf()

//配置NHibernate

//在Configuration中添加HbmMapping

}
public ISessionFactory getFactory()
{
return getConf().BuildSessionFactory();
}
public ISession getSession()
{
return getFactory().OpenSession();
}
public void sessionClose(ISession session)
{
session.Close();
}
}
}
Program.cs的代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using DAL;
using NHibernate;
using Modelse;
using NHibernate.Tool.hbm2ddl;
namespace TestNH
{
class Program
{
static void Main(string[] args)
{
Helper helper = new Helper();
ISession s = helper.getSession();
User user = new User();
//user.Id = 2;
user.Uname = "222";
int num = (int)s.Save(user);
s.Flush();
s.Close();
}
public void sel()
{
Helper helper = new Helper();
ISession s = helper.getSession();
User user = new User();
Type type = user.GetType();
user = (User)s.Get(type, 1);
s.Close();
string str = user.Uname;
}
public void add()
{
Helper helper = new Helper();
ISession s = helper.getSession();
User user = new User();
user.Id = 2;
user.Uname = "222";
s.Save(user);
}
}
}
另附：引用图
这里需要注意的是：User.xml需要在它的属性里面设置为生成操作：嵌入的资源。然后nhibernate下载下来之后在Required_Bins文件夹下有nhibernate-configuration.xsd和nhibernate-mapping.xsd两个文件，需要将他们复制到X:\Program Files\Microsoft Visual Studio 9.0\Xml\Schemas目录下，这样可以在VS中添加hibernate配置文件的提示功能。
