21         public bool Create(string template, string path, string htmlname, Dictionary<string, string> dic, ref string message)
22         {
23             bool result = false;
24             string templatepath = System.Web.HttpContext.Current.Server.MapPath(template);
25             string htmlpath = System.Web.HttpContext.Current.Server.MapPath(path);
26             string htmlnamepath = Path.Combine(htmlpath, htmlname);
27             Encoding encode = Encoding.UTF8;
28             StringBuilder html = new StringBuilder();
29 
30             try
31             {
32                 //读取模版
33                 html.Append(File.ReadAllText(templatepath, encode));
34             }
35             catch (FileNotFoundException ex)
36             {

44                 html.Replace(

62 
63             return result;
64         }
65     }
66 }

模版文件：/Template/a.html

 1 <!DOCTYPE html>
 2 <html xmlns="http://www.w3.org/1999/xhtml">
 3 <head>
 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
 5     <title>$title$</title>
 6 </head>
 7 <body>
 8     $content$<br/>
 9     $author$
10 </body>
11 </html>

调用网页：test.ashx

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Web;
 4 
 5 namespace Wycz
 6 {
 7     /// <summary>
 8     /// test 的摘要说明
 9     /// </summary>
10     public class test : IHttpHandler
11     {
12 
13         public void ProcessRequest(HttpContext context)
14         {
15             //context.Response.ContentType = "text/plain";
16             //context.Response.Write("Hello World");
17             string template = "/Template/a.html";
18             string path = "/test/";
19             string htmlname = "a.html";
20             Dictionary<string, string> dic = new Dictionary<string, string>();
21             Html h = new Html();
22             string message = string.Empty;
23 
24             dic.Add("title", "动态生成html");
25             dic.Add("content", "测试内容");
26             dic.Add("author", "P.R");
27 
28             if (!h.Create(template, path, htmlname, dic, ref message))
29             {
30                 context.Response.Write("出错啦：<br/>");
31                 context.Response.Write(message);
32                 context.Response.End();
33             }
34 
35             context.Response.Redirect(path + htmlname);
36         }
37 
38         public bool IsReusable
39         {
40             get
41             {
42                 return false;
43             }
44         }
45     }
46 }
