 1、静态模板页面 template.html,主要是定义了一些特殊字符,用来被替换。

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN""http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>$Title</title>
</head>
<body>
     <div style="width: 417px; height: 54px" align="center">
         <br />
     $Title</div>
     <div style="width: 417px; height: 8px">
         浏览<font color="red"><script src="http://localhost/.Net/NewsFiles/ClickCount.aspx?NewsId=$NewsId"></script></font>次   $Time</div>
     <div style="width: 417px; height: 100px">
         $Content</div>
     <div style="width: 416px; height: 9px">
         $Pager</div>
     <div style="width: 416px; height: 8px">
     <form id="form1" action="../AddComment.aspx" style="margin:0px">
         <input id="Text1" type="text" /><Img id="Image1" src="../../UserInfo/CheckCode.aspx"/><br />
         <textarea   id="CommentContent" cols="20" rows="2"></textarea>
         <br />
         <input id="NewsId" type="hidden" value="$NewsId"/>
         <input id="Button1" type="submit" value="button" />
         <a href="../Display.aspx?NewsId=$NewsId">查看更多评论</a></form>
         </div>
</body>
</html>

2、前态页面 NewsAdd.aspx,就是一个表单,用来填写新闻的标题和内容。

<%...@ Page Language="C#" AutoEventWireup="false" validateRequest="false" CodeFile="NewsAdd.aspx.cs" Inherits="NewsAdd.Admin_AdminPanel_NewsAdd" %>
<%...@ Register TagPRefix="FCKeditorV2" Namespace="FredCK.FCKeditorV2" Assembly="FredCK.FCKeditorV2" %>
<!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>添加新闻</title>
</head>
<body>
     <form id="form1" runat="server">
     <div>
         <asp:Label ID="Label2" runat="server" Text="标题"></asp:Label>
         <asp:TextBox ID="Title" runat="server" Width="325px"></asp:TextBox><br />
         <asp:Label ID="Label1" runat="server" Text="内容"></asp:Label>
     <FCKeditorV2:FCKeditor id="Content" basePath="~/FCKeditor/"   runat="server" Height="400px" Width="70%"></FCKeditorV2:FCKeditor>
         <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
         <asp:Label ID="Message" runat="server" ></asp:Label></div>
     </form>
</body>
</html>

 

3、后台页面 NewsAdd.aspx.cs

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;
using MySQLserver;
using System.IO;
using System.Text;
namespace NewsAdd
...{
     public partial class Admin_AdminPanel_NewsAdd : System.Web.UI.Page
     ...{
         protected void Page_Load(object sender, EventArgs e)
         ...{

         }
         protected void Button1_Click(object sender, EventArgs e)
         ...{
             string strDate = DateTime.Now.ToString("yyMMdd") + "\" + DateTime.Now.ToString("yyyymmddhhmmss");
             string strFileName = strDate + ".shtml";//存储到数据库
             string strTitle=Request.Form["Title"].ToString().Trim();//接收传过来的标题
             string strContent=Request.Form["Content"].ToString().Trim();//接收传过来的内容
             string[] content = strContent.Split(new Char[] ...{'|'});//对内容进行拆分,并保存到数组
             int upbound = content.Length;//数组的上限
             SqlServerDataBase db = new SqlServerDataBase();
             bool success = db.Insert("insert into inNews(Title,Content,FilePath)values('" + strTitle + "','" + strContent + "','" + strFileName + "')", null);
             //if (success)
                // Message.Text = "添加成功!";
             /**////////////////////////////创建当前日期的文件夹开始
             string dir = Server.MapPath("../../"+"NewsFiles/"+DateTime.Now.ToString("yyMMdd"));//用来生成文件夹
             if (!Directory.Exists(dir))
             ...{
                 Directory.CreateDirectory(dir);
             }
             /**////////////////////////////创建当前日期的文件夹结束
             try
             ...{
             for (int i = 0; i < content.Length; i++)
             ...{
             //string[] newContent = new string[4];//定义和html标记数目一致的数组
             StringBuilder strhtml = new StringBuilder();

                 ...{
                     String oneline;
                     //读取指定的HTML文件模板
                     while ((oneline = sr.ReadLine()) != null)
                     ...{
                         strhtml.Append(oneline);
                     }
                     sr.Close();
                 }

             //为标记数组赋值
             //SqlServerDataBase db = new SqlServerDataBase();
             DataSet ds = db.Select("select top 1 NewsId from inNews order by NewsId desc", null);//获取id
             string strTable = "<table><tr><td>$upUrl</td><td>$Number</td><td>$downUrl</td></tr></table>";//上下页表格,注意此处的$upUrl(上一页),$Number(页码分页),$downUrl(下一页)
             //这三个是用来替换的。

                 string FilePath="";
                 strhtml = strhtml.Replace("$Title", strTitle);
                 strhtml = strhtml.Replace("$NewsId", ds.Tables[0].Rows[0]["NewsId"].ToString());

                 string strNumber = "";//数字分页1,2,3……
                 for (int m = 1; m <=upbound; m++)
                 ...{
