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。

复制代码代码如下:

<!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>
<br />
Title</div>
<div>
浏览<font color="red"><script src="http://localhost/.Net/NewsFiles/ClickCount.aspx?NewsId=NewsId"></script></font>次 Time</div>
<div>
Content</div>
<div>
Pager</div>
<div>
<form action="../AddComment.aspx">
<input type="text" /><Img src="http://www.d"/><br />
<textarea cols="20" rows="2"></textarea>
<br />
<input type="hidden" value="NewsId"/>
<input type="submit" value="button" />
<a href="http://www.d?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。

复制代码代码如下:

<%@ Page Language="C#" 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 runat="server">
<div>
<asp:Label runat="server" Text="标题"></asp:Label>
<asp:TextBox runat="server"></asp:TextBox><br />
<asp:Label runat="server" Text="内容"></asp:Label>
<FCKeditorV2:FCKeditor basePath="~/FCKeditor/" runat="server"></FCKeditorV2:FCKeditor>
<asp:Button runat="server" Text="Button" />
<asp:Label runat="server" ></asp:Label></div>
</form>
</body>
</html>

3、后台页面 NewsAdd.aspx.cs

复制代码代码如下:

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
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("http://www.cnblogs.com/") + "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("http://www.cnblogs.com/") + "NewsFiles" + "//" + strDate + ".shtml";
else
FilePath = Server.MapPath("http://www.cnblogs.com/") + "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());
}
}
}
}
