ASP.NET2.0学习5--N层代码示例(一)

ASP.NET2.0学习5--N层代码示例

一、数据库Test,

表：create table Customers

(

       CustId int IDENTITY(1,1) primary key,

       CustName varchar(20) not null,

       Address varchar(50),

       Linkman varchar(20)

)

//insert into Cusomers values('ggg','xuzhou','zhangsan');

二、配置文件web.config

<?xml version="1.0"?>

<configuration>

     <appSettings/>

     <connectionStrings>

         <add name="TestConnectionString" connectionString="Data Source=GONGCHL;Initial Catalog=Test;Persist Security Info=True;User ID=sa;Password=123" providerName="System.Data.SqlClient"/>

     </connectionStrings>

     <system.web>

         <compilation debug="true"/>

         <authentication mode="Windows"/>

     </system.web>

</configuration>

三、业务实体

using System;

using System.Collections.Generic;

using System.Text;

namespace com.Model

{

    /// <summary>

    /// 业务实体CustomerInfo

    /// </summary>

    [Serializable]

    public class CustomerInfo

    {

        /// <summary>

        /// 默认的构造函数

        /// </summary>

        public CustomerInfo()  {}

        /// <summary>

        /// 有参数的构造函数

        /// </summary>

        /// <param name="custId">客户号</param>

        /// <param name="custName">客户名称</param>

        /// <param name="address">客户地址</param>

        /// <param name="linkman">联系人</param>

        public CustomerInfo(int custId, string custName, string address, string linkman)

       {

            this.custId = custId;

            this.custName = custName;

            this.address = address;

            this.linkman = linkman;

        }

        private int custId;

        public int CustId

        {

            get { return custId; }

            set { custId = value; }

        }

        private string custName;

        public string CustName

        {

            get { return custName; }

            set { custName = value; }

        }

        private string address;

        public string Address

        {

            get { return address; }

            set { address =
