Your first NHibernate based application - NHibernate

创建Winform应用程序

创建Winform项目NHibernate，NuGet引入NHibernate包

创建数据库表

USE MASTER
GOIF EXISTS (SELECT TOP 1 1 FROM SYSDATABASES WHERE NAME='Demo')DROP DATABASE Demo
GOCREATE DATABASE Demo
GOUSE Demo
GOIF EXISTS (SELECT TOP 1 1 FROM SYSOBJECTS WHERE NAME='TestTable')DROP TABLE TestTable
GOCREATE TABLE TestTable
(Id NVARCHAR(50) PRIMARY KEY NOT NULL,Contents NVARCHAR(100)
)
GO

创建实体类和xml文件

TestTable.cs

属性一定要加Virtual

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace NHibernateDemo.Entity
{public class TestTable{public virtual string Id {  get; set; }public virtual string Contents {  get; set; }}
}

TestTable.hbm.xml

主键一定要用Id标签写，固定写法

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"assembly="NHibernateDemo"namespace="NHibernateDemo.Entity"><class name="TestTable" table="TestTable"><id name="Id" column="Id" type="String"><generator class="native"/></id><property name="Contents" column="Contents" type="String"/></class>
</hibernate-mapping>

hibernate.cfg.xml

<!-- 示例的hibernate.cfg.xml配置 -->
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"><session-factory><!-- 数据库连接设置 --><property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property><property name="connection.driver_class">NHibernate.Driver.Sql2008ClientDriver</property><property name="connection.connection_string">Server=.;Database=Demo;User Id=sa;Password=123;</property><!-- SQL方言 --><property name="dialect">NHibernate.Dialect.MsSql2008Dialect</property><!-- 映射文件的位置 --><mapping assembly="NHibernateDemo" resource="NHibernateDemo.Entity.TestTable.hbm.xml"/></session-factory>
</hibernate-configuration>

创建SessionFactory的类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using NHibernate;namespace NHibernateDemo
{public class MySessionFactory{private static ISessionFactory _sessionFactory;private static ISessionFactory SessionFactory{get{if (_sessionFactory == null){var configuration = new NHibernate.Cfg.Configuration();_sessionFactory = configuration.Configure("hibernate.cfg.xml").BuildSessionFactory();}return _sessionFactory;}}public static ISession OpenSession(){return SessionFactory.OpenSession();}}
}

查询

private void BtnQuery_Click(object sender, EventArgs e)
{using (var session = MySessionFactory.OpenSession()){var list = session.QueryOver<TestTable>().List().ToList();}
}
