　　asp.net|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"?>

</connectionStrings>

<system.web>

</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 = value; }

}

private string linkman;

public string Linkman

{

get { return linkman; }

set { linkman = value; }

}
