下图是三层架构列表，Models里面有模拟数据库中列的类，DAL中有DBHelper和service,BLL中有BllManager文件用于ui界面直接调用
建照片文件夹用于展示图片，数据库存地址
2、添加引用关系
DAL引用Models文件，BLL引用DAL和Models文件，主文件WebApplication1引用Bll和Models
3、根据数据库中的列写Models下的XueshengModels类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Models
public class NewsModels
private string newsID;
public string NewsID
get { return newsID; }
set { newsID = value; }
private string newsTitle;
public string NewsTitle
get { return newsTitle; }
set { newsTitle = value; }
private string newsContent;
public string NewsContent
get { return newsContent; }
set { newsContent = value; }
private string type;
public string Type
get { return type; }
set { type = value; }
private string publisher;
public string Publisher
get { return publisher; }
set { publisher = value; }
private string pian;
public string Pian
get { return pian; }
set { pian = value; }
private string pubTime;
public string PubTime
get { return pubTime; }
set { pubTime = value; }
4、DAL下的DBHelper（对数据库进行操作）
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data.SqlClient;
namespace DAL
public class DBHelper
public static string connstr = "server=.;database=NewsDB;uid=sa;pwd=123123";
public static SqlConnection conn = null;
public static void Conncet() {
if (conn==null)
conn=new SqlConnection(connstr);
conn.Close();
conn.Open();
public static bool NoQuery(string sql) {
Conncet();
SqlCommand cmd = new SqlCommand(sql,conn);
int temp= cmd.ExecuteNonQuery();
conn.Close();
return temp > 0;
public static SqlDataReader Reader(string sql) {
Conncet();
SqlCommand cmd = new SqlCommand(sql, conn);
return cmd.ExecuteReader(System.Data.CommandBehavior.CloseConnection);
5、DAL数据访问层下的service文件
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data.SqlClient;
namespace DAL
public class DalService
public static List<Models.NewsModels> Zhanshi() {
List<Models.NewsModels> list = new List<Models.NewsModels>();
string sql = "select * from News";
SqlDataReader read= DBHelper.Reader(sql);
while (read.Read())
Models.NewsModels model=new Models.NewsModels();
model.NewsID = read["NewsID"].ToString();
model.NewsTitle = read["NewsTitle"].ToString();
model.Pian = read["Pian"].ToString();
model.Publisher = read["Publisher"].ToString();
model.Type = read["Type"].ToString();
model.PubTime = read["PubTime"].ToString();
model.NewsContent = read["NewsContent"].ToString();
list.Add(model);
return list;
public static List<Models.NewsModels> Cha(string title)
List<Models.NewsModels> list = new List<Models.NewsModels>();
string sql = string.Format("select * from News where NewsTitle like '%{0}%'",title);
SqlDataReader read = DBHelper.Reader(sql);
while (read.Read())
Models.NewsModels model = new Models.NewsModels();
model.NewsID = read["NewsID"].ToString();
model.NewsTitle = read["NewsTitle"].ToString();
model.Pian = read["Pian"].ToString();
model.Publisher = read["Publisher"].ToString();
model.Type = read["Type"].ToString();
model.PubTime = read["PubTime"].ToString();
model.NewsContent = read["NewsContent"].ToString();
list.Add(model);
return list;
public static bool Jia(string title,string content,string type,string publisher){
string sql=string.Format("insert News values('{0}','{1}','{2}','{3}','Jellyfish.jpg',GETDATE())",title,content,type,publisher);
if (DBHelper.NoQuery(sql))
return true;
return false;
6、BLL业务逻辑层下调用DAL的文件
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace BLL
public class BllManager
public static List<Models.NewsModels> Zhanshi() {
return DAL.DalService.Zhanshi();
public static bool Jia(string title, string content, string type, string publisher) {
return DAL.DalService.Jia(title,content,type,publisher);
public static List<Models.NewsModels> Cha(string title) {
return DAL.DalService.Cha(title);
7、ui表现层主界面前端部分
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Index.aspx.cs" Inherits="Index.Index" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
</head>
<form id="form1" runat="server">
<a href="TianJia.aspx">添加新闻</a>
<br /> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><asp:Button ID="Button1" runat="server" Text="查询" OnClick="Button1_Click" />
<asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand">
<HeaderTemplate>
<table border="1" >
</th> <th>
</th><th>
</th> <th>
</th> <th>
</HeaderTemplate>
<ItemTemplate>
<%#Eval("NewsID") %>
<%#Eval("NewsTitle") %>
<%#Eval("NewsContent") %>
<img src="Img/<%#Eval("Pian") %>" height="50px" width="50px"/>
<%#Eval("Type") %>
<%#Eval("Publisher") %>
<%#Eval("PubTime") %>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
</form>
</body>
</html>
8、ui表现层主界面后端部分
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace Index
public partial class Index : System.Web.UI.Page
protected void Page_Load(object sender, EventArgs e)
if (!IsPostBack)
List<Models.NewsModels> list = BLL.BllManager.Zhanshi();
Repeater1.DataSource = list;
Repeater1.DataBind();
protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
protected void Button1_Click(object sender, EventArgs e)
List<Models.NewsModels> list = BLL.BllManager.Cha(TextBox1.Text.ToString());
Repeater1.DataSource = list;
Repeater1.DataBind();
9、ui表现层添加界面前端部分
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="TianJia.aspx.cs" Inherits="Index.TianJia" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
</head>
<form id="form1" runat="server">
<a href="Index.aspx">返回</a>
<br /> <asp:Label ID="Label1" runat="server" Text="标题"></asp:Label><asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="标题不能为空" ControlToValidate="TextBox1"></asp:RequiredFieldValidator>
<br /> <asp:Label ID="Label2" runat="server" Text="内容"></asp:Label><asp:TextBox Height="100px" ID="TextBox2" runat="server" TextMode="MultiLine"></asp:TextBox><asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ErrorMessage="内容不能为空" ControlToValidate="TextBox2"></asp:RequiredFieldValidator>
<br /> <asp:Label ID="Label3" runat="server" Text="类型"></asp:Label><asp:TextBox ID="TextBox3" runat="server"></asp:TextBox><asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server" ErrorMessage="类型不能为空" ControlToValidate="TextBox3"></asp:RequiredFieldValidator>
<br /> <asp:Label ID="Label4" runat="server" Text="发布人"></asp:Label><asp:TextBox ID="TextBox4" runat="server"></asp:TextBox><asp:RequiredFieldValidator ID="RequiredFieldValidator4" runat="server" ErrorMessage="发布人不能为空" ControlToValidate="TextBox4"></asp:RequiredFieldValidator>
<br /> <asp:Button ID="Button1" runat="server" Text="添加" OnClick="Button1_Click" />
</form>
</body>
</html>
10、ui表现层添加界面后端部分
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace Index
public partial class TianJia : System.Web.UI.Page
protected void Page_Load(object sender, EventArgs e)
UnobtrusiveValidationMode = UnobtrusiveValidationMode.None;
protected void Button1_Click(object sender, EventArgs e)
if (BLL.BllManager.Jia(TextBox1.Text.ToString(), TextBox2.Text.ToString(), TextBox3.Text.ToString(), TextBox4.Text.ToString()))
ClientScript.RegisterStartupScript(this.GetType(), "success", "alert('成功添加');location.href='Index.aspx'",true);
ClientScript.RegisterStartupScript(this.GetType(), "fail", "alert('失败');", true);

3.新闻内容的图文混排，并自动获取发布新闻里的所有图片
4.获取新闻图片，显示成滚动flash图片，即做成图片新闻样式（本案例只是获取图片，要flash滚动图片请大家扩展）
5.删除新闻同时删除新闻中的图片，防止垃圾的产生（图片都取出来了，自己扩展删除）
6.鼠标移动到新闻标题，显示详细标题，主要是a 标记title属性的使用，换行是
from lxml import etreeimport requestsimport osBASE_DOMAIN = "http://m2.people.cn/"HEADERS={'User-Agent':'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/...
