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;
        }
