小议ASP.NET模板引擎技术的使用
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
我們將從PHP模板引擎技術談談ASP.NET模板引擎技術，希望通過本文的實例和代碼，能讓大家在今后的開發過程中更加靈活的運用ASP.NET模板引擎技術。
以前聽我朋友說起php的模板引擎技術的時候似懂非懂哪時感覺真的很強，一直在想asp.net有這種技術嗎？我不知道我的理解是不是對的.其實asp.net模板引擎技術就是先建好一個靜態的html頁面我們稱它為模板頁，你如果有不同形式的頁面哪就得建立不同的靜態模板頁，然后在后臺用文件操作往這個文件里寫東西然后在把這個模板頁另存到一個靜態頁面的目錄，不好意思可能我的理解太俗，如果有更好的理解和想法可以在apolov發文章告訴我謝謝。現在我附加一下代碼
Default.aspx這個頁面只有幾個textbox控件和兩個按妞控件
<%@?Page?Language="C#"?AutoEventWireup="true"?CodeBehind="Default.aspx.cs"?ValidateRequest="false"?Inherits="ToHtml._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生成靜態頁</title>?</head>?<body>?????<form?id="form1"?runat="server">?????<div>?????????標題：<asp:TextBox?ID="txtTitle"?runat="server"?Width="352px"></asp:TextBox><br?/>?????????內容：<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="根據模板生成"?/><br?/>?????????<br?/>?????????<br?/>?????????Url地址：<asp:TextBox?ID="txtUrl"?runat="server"?ToolTip="請確認Url地址的存在"?Width="359px"></asp:TextBox>?????????<br?/>?????????<br?/>?????????<asp:Button?ID="Button2"?runat="server"?Text="根據Url地址生成"?OnClick="Button2_Click"?/></div>?????</form>?</body>?</html>?要準備的模板頁代碼，htm文件頁面比較簡單，如果有興趣的朋友可以做成更復雜的模板頁嘿嘿
!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>?$title$?生成靜態頁title>?????<style?type="text/css">?<!-- ?.STYLE1?{ ??font-size:?16px; ??font-weight:?bold; ?} ?-->?????</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?/>?????內容：$content$?</td>???</tr>?</table>??</body>?</html>?后臺生成靜態頁面的代碼Default.aspx.cs主要用到了文件操做
