.NET生成静态页面例子

转自:http://blog.csdn.net/hankwen/archive/2008/11/27/3388941.aspx

近期做一个项目，需要将用户添加的表单生成静态页面，这个东西很早就有了，大部分是用在新闻系统里面，新闻添加后生成静态页面，只将文章标题，简介，连接地址等简单信息存入数据库，没办法只能再研究一下了！

时间有限，只是功能实现了！主要做法如下：

1、创建网站，并创建一个模板页，template.htm

2、添加一个web窗体Default.aspx

3、在网站下新建文件夹htm，设置该文件夹的属性，确保该文件夹具有可写权限

详细代码

1、template.htm

<!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>
    <title> $title$ 生成静态页</title>
    <style type="text/css">

    </style>
</head>
<body>
<br />
<br />
<table width="100%" border="0" bgcolor="#339900">
<tr>
    <td height="34" align="center" bgcolor="#FFFFFF"><span class="STYLE1">$title$ </span></td>
</tr>
<tr>
    <td height="42" bgcolor="#FFFFFF"><br />
      <br />
    内容：$content$ </td>
</tr>
</table>

</body>
</html>
2、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>Asp.net生成静态页的两个例子</title>
</head>
<body>
    <<form id="form1" runat="server">
    <div>
        标题：<asp:TextBox ID="txtTitle" runat="server" Width="352px"></asp:TextBox><br />
        内容：<asp:TextBox ID="txtContent" runat="server" Height="179px" TextMode="MultiLine"
            Width="350px"></asp:TextBox><br />
        <br />
        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="根据模板生成" /><br />
        <br />
        <br />
        Url地址：<asp:TextBox ID="txtUrl" runat="server" ToolTip="请确认Url地址的存在" Width="359px"></asp:TextBox>
        <br />
        <br />
        <asp:Button ID="Button2" runat="server" Text="根据Url地址生成" OnClick="Button2_Click" /></div>
    </form>
</body>
</html>

3、后台代码Default.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 System.Net;
using System.Text;
using System.IO;

public partial class Default2: System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

    }
    //根据模板生成，保持在html文件夹中
    protected void Button1_Click(object sender, EventArgs e)
    {
        //源码是替换掉模板中的特征字符

        string mbPath = Server.MapPath("template.htm");
        Encoding code = Encoding.GetEncoding("gb2312");
        StreamReader sr = null;
        StreamWriter sw = null;
        string str = null;

        //读取
        try
        {
            sr = new StreamReader(mbPath, code);
            str = sr.ReadToEnd();

        }
        catch (Exception ex)
        {
            throw ex;
        }
        finally
        {
            sr.Close();
        }

        //根据时间自动重命名，扩展名也可以自行修改
        string fileName = DateTime.Now.ToString("yyyyMMddHHmmss") + ".htm";
        str = str.Replace("$title$", txtTitle.Text);//替换Title
        str = str.Replace("$content$", txtContent.Text);//替换content

        //生成静态文件
        try
        {
            sw = new StreamWriter(Server.MapPath("htm/") + fileName, false, code);
            sw.Write(str);
            sw.Flush();

        }
        catch (Exception ex)
        {
            throw ex;
        }
        finally
        {
            sw.Close();
            Response.Write("恭喜<a href=htm/" + fileName + " target=_blank>" + fileName + "</a>已经生成，保存在htm文件夹下！");
        }

    }
    //根据Url地址生成静态页保持
    protected void Button2_Click(object sender, EventArgs e)
    {
        Encoding code = Encoding.GetEncoding("utf-8");
        StreamReader sr = null;
        StreamWriter sw = null;
        string str = null;

        //读取远程路径
        WebRequest temp = WebRequest.Create(txtUrl.Text.Trim());
        WebResponse myTemp = temp.GetResponse();
        sr = new StreamReader(myTemp.GetResponseStream(), code);
        //读取
        try
        {
            sr = new StreamReader(myTemp.GetResponseStream(), code);
            str = sr.ReadToEnd();

        }
        catch (Exception ex)
        {
            throw ex;
        }
        finally
        {
            sr.Close();
        }
        string fileName = DateTime.Now.ToString("yyyyMMddHHmmss") + ".htm";

        //写入
        try
        {
            sw = new StreamWriter(Server.MapPath("htm/") + fileName, false, code);
            sw.Write(str);
            sw.Flush();
