NHibernate + AspNetPager 实现分页

NHibernate + AspNetPager 实现分页

白折腾了一天，原来NHibernate的 各种 Dll的版本不一样，配置文件经常找不到路径，

换了好几个源码都无法正常运行， 最后在CodeProject.com里找到一个思路比较清晰的Demo，

郁闷的是居然没有数据库文件，自己勉强从实体层xml还原数据库，呵呵，这会可OK了。

不知分页效果如何，顺便把分页也写进去，当然首选应该是 AspNetPager 吧，刚好集成一下，还不懒！

性能比较就没有测试过了，不知和Ado.Net相比，效果如何，本人一直都是用Ado.Net的，有望高手指点一下！！

效果图：



Sql文件

USE [NTest]
GO
/****** 对象: Table [dbo].[Customer] 脚本日期: 04/01/2011 09:31:46 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[Customer](
[CustomerID] [int] NOT NULL,
[AccountNumber] [nchar](10) COLLATE Chinese_PRC_CI_AS NULL,
[CustomerType] [nchar](10) COLLATE Chinese_PRC_CI_AS NULL,
[TerritoryID] [int] NULL,
CONSTRAINT [PK_Customer] PRIMARY KEY CLUSTERED
(
[CustomerID] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

NHibernateDataProvider.cs

分页函数

/// <summary>
/// 获取分页
/// </summary>
/// <param name="pageStart"></param>
/// <param name="pageLimit"></param>
/// <returns></returns>
public IList<Customer> GetCustomerPageModel(int pageStart, int pageLimit)
{
//HQL查询
IList<Customer> customerList = GetSession().CreateQuery("from Customer")
.SetFirstResult(pageStart * pageLimit)
.SetMaxResults(pageLimit)
.List<Customer>();
return customerList;

//条件查询
//return Session.CreateCriteria(typeof(Customer))
// .SetProjection(Projections.ProjectionList()
// .Add(Projections.Property("Id"), "Id")
// .Add(Projections.Property("Name"), "Name")
// .Add(Projections.Property("Tel"), "Tel")
// .Add(Projections.Property("Address"), "Address")
// .Add(Projections.Property("Sex"), "Sex")
// .Add(Projections.Property("CreateDate"), "CreateDate"))
// .AddOrder(Order.Asc("Id"))
// .SetFirstResult(pageStart * pageLimit)
// .SetMaxResults(pageLimit)
// .SetResultTransformer(Transformers.AliasToBean(typeof(Customer)))
// .List<Customer>();

//SQL查询
//IList<Customer> customerList = Session.CreateSQLQuery("SELECT * FROM Customer")
// .SetFirstResult(pageStart*pageLimit)
// .SetMaxResults(pageLimit)
// .SetResultTransformer(Transformers.AliasToBean<Customer>()).List<Customer>();
//return customerList;
}
