.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>

<title>$Title</title>

</head>

<body>

<br />

$Title</div>

浏览<font color="red"><script src="NewsId]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>
