.NET新闻发布生成静态页面并实现分页
-
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
...{

}
//创建文件信息对象--------------------------------------------
FileInfo finfo = new FileInfo(FilePath);

catch (Exception err)
...{
//输出异常信息
Response.Write(err.ToString());
