Asp.Net三层架构调用存储过程，详细例子（不带model层的）

首先 进行数据库操作

1、建立一个数据库【User】，建立一张数据表【UserInfo】

包含四个字段 UserID int,   UserName varchar(50),    UserSex varchar(10),     UserDesc varchar(50) 其中UserID为自动增长列

2、创建存储过程

（1）、查找表中所有数据

       create procedure [dbo].[uInfo_select]
       as
       select * from userInfo

（2）、根据ID查找表中数据

      create procedure [dbo].[uInfo_select_uid]
      @uID int
      as
      select * from UserInfo where UserID = @uID

（3）、向表中插入数据

      create procedure [dbo].[uInfo_inSert] 
      @uName varchar(50),
      @uSex varchar(10),
      @uDesc varchar(100)
      as
      insert into userInfo(UserName,UserSex,UserDesc) values (@uName,@uSex,@uDesc)

（4）、更新表中数据

      create procedure [dbo].[uInfo_update] 
      @uID int,
      @uName varchar(50),
      @uSex varchar(10),
      @uDesc varchar(100)
      as
      update userInfo set UserName=@uName,UserSex=@uSex,UserDesc=@uDesc where UserID = @uID

（5）、删除表中某条记录

      create procedure [dbo].[uInfo_delete] 
      @uID int
      as
      delete userInfo where UserID = @uID

二、DAL 里面

类名叫：DAL_uInfo    要引用接口层IDAL （其他删除什么的方法我也都写了 ，本例只实现一个添加，其他的自己写吧。）

using System;
using System.Collections.Generic;
using System.Text;

                }
            }
        }
    }

三、BLL里面

类名叫：BLL_uInfo

using System;
using System.Collections.Generic;
using System.Text;

using System.Data;

namespace BLL
{
    public class BLL_uInfo
    {

        IDAL.IDAL_uInfo dal = new DAL.DAL_uInfo();

        /// <summary>
        /// 查询表中所有的数据
        /// </summary>
        /// <returns></returns>
        public DataSet uinfo_select()
        {
            return dal.uinfo_select();
        }

        /// <summary>
        /// 查询表中所有的数据
        /// </summary>
        /// <param name="ID">根据ID</param>
        /// <returns></returns>
        public DataSet uinfo_select_id(int ID)
        {
            return dal.uinfo_select(ID);
        }

        /// <summary>
        /// 向表中插入数据
        /// </summary>
        /// <param name="uName">用户名称</param>
        /// <param name="uSex">性别</param>
        /// <param name="uDesc">信息</param>
        public void uinfo_insert(string uName, string uSex, string uDesc)
        {
            dal.uinfo_insert(uName, uSex, uDesc);
        }

        /// <summary>
        /// 更新表中数据
        /// </summary>
        /// <param name="uID">用户ID</param>
        /// <param name="uName">名称</param>
        /// <param name="uSex">性别</param>
        /// <param name="uDesc">信息</param>
        public void uinfo_update(int uID, string uName, string uSex, string uDesc)
        {
            dal.uinfo_update(uID, uName, uSex, uDesc);
        }

        /// <summary>
        /// 删除表中数据
        /// </summary>
        /// <param name="uID">用户ID</param>
        public void uinfo_delete(int uID)
        {
            dal.uinfo_delete(uID);
        }
    }
}

四、IDAL(接口层)

类名：IDAL_uInfo

using System;
using System.Collections.Generic;
using System.Text;
using System.Data.SqlClient;
using System.Data;

namespace IDAL
{
    public interface IDAL_uInfo
    {
        
        /// <summary>
        /// 查询表中所有的数据
        /// </summary>
        /// <returns></returns>
        DataSet uinfo_select();

        /// <summary>
        /// 查询表中所有的数据
        /// </summary>
        /// <param name="ID">根据ID</param>
        /// <returns></returns>
        DataSet uinfo_select(int ID);

        /// <summary>
        /// 向表中插入数据
        /// </summary>
        /// <param name="uName">用户名称</param>
        /// <param name="uSex">性别</param>
        /// <param name="uDesc">信息</param>
        void uinfo_insert(string uName, string uSex, string uDesc);

        /// <summary>
        /// 更新表中数据
        /// </summary>
        /// <param name="uID">用户ID</param>
        /// <param name="uName">名称</param>
        /// <param name="uSex">性别</param>
        /// <param name="uDesc">信息</param>
        void uinfo_updata(int uID, string uName, string uSex, string uDesc);

        /// <summary>
        /// 删除表中数据
        /// </summary>
        /// <param name="uID">用户ID</param>
        void uinfo_delete(int uID);

    }
}

五、UI

1、界面代码

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="CunchuDiaoyong._Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>无标题页</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        <br />
        <br />
        <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox><br />
        <br />
        <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox><br />
        <br />
        <asp:Button ID="btnAdd" runat="server" OnClick="btnAdd_Click" Text="添 加" /></div>
    </form>
</body>
</html>

2、后台代码

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

namespace CunchuDiaoyong
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void btnAdd_Click(object sender, EventArgs e)
        {
            string a = TextBox1.Text.Trim();
            string b = TextBox2.Text.Trim();
            string c = TextBox3.Text.Trim();

            BLL.BLL_uInfo User = new BLL.BLL_uInfo();
            User.uinfo_insert(a, b, c);

        }
    }
}

六、Web.config

<?xml version="1.0" encoding="utf-8"?>

<configuration>

<appSettings>
    <add key="ConnDb" value="Server=192.168.18.246;Database=Sy_User;User ID=sa;Pwd=123"/>
</appSettings>
    <connectionStrings/>

    <system.web>
        <!-- 
            设置 compilation debug="true" 将调试符号插入
            已编译的页面中。但由于这会 
            影响性能，因此只在开发过程中将此值 
            设置为 true。
        -->
        <compilation debug="true" />
        <!--
            通过 <authentication> 节可以配置 ASP.NET 使用的 
            安全身份验证模式，
            以标识传入的用户。 
        -->
        <authentication mode="Windows" />
        <!--
            如果在执行请求的过程中出现未处理的错误，
            则通过 <customErrors> 节可以配置相应的处理步骤。具体说来，
            开发人员通过该节可以配置
            要显示的 html 错误页
            以代替错误堆栈跟踪。

        <customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
            <error statusCode="403" redirect="NoAccess.htm" />
            <error statusCode="404" redirect="FileNotFound.htm" />
        </customErrors>
        -->
    </system.web>
</configuration>

可以了，直接复制过去就可以用，想学习的话，还是必须得自己打几遍，设个断点，一步一步，一遍一遍的看，知道看会为止，学习没有好的技巧，Never Give Up!加油！
