ASP.NET生成静态页面和分页主要的原理就是替换模板里的特殊字符。

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">
        $Pager</div>
    <div style="width: 416px; height: 8px">
    <form id="form1" action="../AddComment.aspx" style="margin:0px">
        <input id="Text1" type="text" /><Img id="Image1" src="http://www.cnblogs.com/UserInfo/CheckCode.aspx"/><br />
        <textarea id="CommentContent" cols="20" rows="2"></textarea>
        <br />
        <input id="NewsId" type="hidden" value="$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">

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";//存储到数据库中
            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("http://www.cnblogs.com/"+"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();

                //创建StreamReader对象
                using (StreamReader sr = new StreamReader(Server.MapPath("http://www.cnblogs.com/" + "NewsFiles/") + ""template.html",Encoding.GetEncoding("gb2312")))
                ...{
                    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());
                strhtml = strhtml.Replace("$Time", DateTime.Now.ToString("yyyy/MM/dd"));
                strhtml = strhtml.Replace("$Content", content[i]);
                string strNumber = "";//数字分页1，2，3……
                for (int m = 1; m <=upbound; m++)
                ...{
                    if (m == 1)//如果是第一页就显示成这个样子：20070524.shtml而不是20070524_1.shtml

                    ...{
