生成静态页面——C#+asp.net————重点在于Replace
主要包含三个页面文件TempHtml.html(模板文件),default.aspx(上传新闻内容页面),deault.aspx.cs(后台实现代码)：
新闻模板文件（TempHtml.html）：
<html>
<head>
<title>$htmlkey[0]</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
</head>
<body >
<table $htmlkey[1] height="100%" border="0" width="100%" cellpadding="10" cellspacing="0" bgcolor="#eeeeee" style="border:1px solid #000000">
<tr>
<td width="100%" valign="middle" align="left">
<span style="color: $htmlkey[2];font-size: $htmlkey[3]"><marquee>$htmlkey[4]</marquee></span>
</td>
</tr>
</table>
</body>
</html>
上传新闻内容页面：default.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="default.aspx.cs" Inherits="default" %>
<!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>Untitled Page</title>
</head>
<body>
<form >
<asp:Button
runat="server" Text="创建HTML文件" OnClick="btnCreate_Click"></asp:Button>
<asp:TextBox
runat="server" TextMode="MultiLine" Height="402px" Width="352px"></asp:TextBox>
<asp:HyperLink
runat="server" Target="_blank">创建的HTML文件</asp:HyperLink>
<asp:TextBox
Width="352px"></asp:TextBox>
<asp:Label >页面标题</asp:Label>
<asp:Label >页面内容</asp:Label>
</form>
</body>
</html>
