由于公司的产品需要用asp开发，那么我们一般都会在asp中生成静态页面并分页的程序，那么现在我们就跟爱站小编一起去解析Asp.NET生成静态页面并分页的代码。

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 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.dwww.cn/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="http://www.dwww.cn/News/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。

复制代码代码如下:

<%@ 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

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 stockbests.cn

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！"; stockbests.cn

/**////////////////////////////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());

}

}

}

}
