.NET生成静态页面并分页

来源：互联网发布：关闭win7哪些端口安全编辑：程序博客网时间：2024/04/30 04:08

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>

<title>$Title</title>

</head>

<body>

<br />

$Title</div>

浏览<font color="red"><script src="http://localhost/.Net/NewsFiles/ClickCount.aspx?NewsId=$NewsId"></script></font>次 $Time</div>

$Content</div>

$Pager</div>

<br />

<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">

</head>

<body>

<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("../../"+"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("../../" + "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

strNumber = strNumber + " ["+"<a href=" + "../" + strDate + ".shtml" + ">" + m + "</a>"+"] ";

else

{

int n = m - 1;//第三页的连接应该是20070524_2.shtml，以此类推

strNumber = strNumber + " [" +"<a href=" + "../" + strDate + "_" + n + ".shtml" + ">" + m + "</a>"+"] ";

}

if (upbound == 0)//如果没有分页，就直接按日期时间保存

{

FilePath = Server.MapPath("../../") + "NewsFiles" + "//" + strDate + ".shtml";

strhtml = strhtml.Replace("$Pager", "");

}

else//否则按20070524.shtml、20070524_1.shtml 这种效果保存

{

if (i == 0)

FilePath = Server.MapPath("../../") + "NewsFiles" + "//" + strDate + ".shtml";

else

FilePath = Server.MapPath("../../") + "NewsFiles" + "//" + strDate + "_" + i + ".shtml";

if (i == 0)//第一页不显示上一页

strTable = strTable.Replace("$upUrl", "");

if (i <= 1)//上一页分页

strTable = strTable.Replace("$upUrl", "<a href=" + "../" + strDate + ".shtml" + ">上一页</a>");

else

{

int p = i - 1;

strTable = strTable.Replace("$upUrl", "<a href=" + "../" + strDate + "_" + p + ".shtml" + ">上一页</a>");

}

if(upbound==1)//如果只有一页，则不显示页码

//strNumber="";

strTable = strTable.Replace("$Number", "");

else

strTable = strTable.Replace("$Number", strNumber);//页码替换

////////////////////////

if(i==upbound-1)//最后一页不显示下一页

strTable = strTable.Replace("$downUrl", "");

if (i != upbound - 1)//下一页分页

{

int q = i + 1;

strTable = strTable.Replace("$downUrl", "<a href=" + "../" + strDate + "_" + q + ".shtml" + ">下一页</a>");

}

else

{

int j = upbound - 1;

strTable = strTable.Replace("$downUrl", "<a href=" + "../" + strDate + "_" + j + ".shtml" + ">下一页</a>");

}

strhtml = strhtml.Replace("$Pager", strTable);

}

//创建文件信息对象--------------------------------------------

FileInfo finfo = new FileInfo(FilePath);

//以打开或者写入的形式创建文件流

using (FileStream fs = finfo.OpenWrite())

{

//根据上面创建的文件流创建写数据流

StreamWriter sw = new StreamWriter(fs, System.Text.Encoding.Default);

//把新的内容写到创建的HTML页面中

sw.WriteLine(strhtml);

sw.Flush();

sw.Close();

}

catch (Exception err)

{

//输出异常信息

Response.Write(err.ToString());

}

请不要直接拷贝使用，里面的路径需要更改，但程序绝对没问题，在我本地已经测试通过。

另外在使用时，比如我要把新闻的内容分成4页，就应该这样写：111|222|333|444。
