生成静态网页

方式1(模版):
   在模版中编辑一些符号,然后从数据库中提取数据替换这些符号并按照时间(年-月-日)或其他的规则生成到硬盘中.这种方式过于简单在此不在累述.

方式2( HttpWebRequest):
   

  1         ///   <summary>
  2           ///  Write the HTML file.
  3           ///   </summary>
  4           ///   <param name="PageUrl"> The page URL. </param>
  5           ///   <param name="EncodeTypeStr"> The encode type STR. </param>
  6           ///   <param name="LocalDiskPath"> The local disk path. </param>
  7           ///   <remarks> </remarks>
  8           ///   <example>
  9           ///   <code>
10           ///   <![CDATA[
11          ///  WriterHtmlFile("/TDD2005/Rpt_TodayFocus.aspx", "utf-8", "/TDD2005/Rpt_TodayFocus.htm")
12           ///  ]]>
13           ///   </code>
14           ///   </example>
15           ///   <returns> Is success </returns>
16           public   static   bool  WriteHtmlFile( string  PageUrl,  string  EncodeTypeStr,  string  LocalDiskPath)
17          {
18               try
19              {
20                  File.Delete(HttpContext.Current.Server.MapPath(LocalDiskPath));
21                   string  text  =   " <!--#include virtual=\ " hehe\ " --> " ;
22                  
23                  HttpWebRequest request  =  (HttpWebRequest)WebRequest.Create( " http:// "   +  HttpContext.Current.Request.ServerVariables[ " SERVER_NAME " ]  +  PageUrl);
24                  request.Timeout  =   0xc350 ;
25                  HttpWebResponse response  =  (HttpWebResponse)request.GetResponse();
26                  Encoding encoding  =  Encoding.GetEncoding(EncodeTypeStr);
27                  StreamReader reader  =   new  StreamReader(response.GetResponseStream(), encoding);
28                  text  =  reader.ReadToEnd();
29                  response.Close();
30                  reader.Close();
31                  StreamWriter writer  =   new  StreamWriter(HttpContext.Current.Server.MapPath(LocalDiskPath),  true , Encoding.GetEncoding(EncodeTypeStr));
32                  writer.WriteLine(text);
33                  writer.Close();
34                   return   true ;
35              }
36               catch (Exception ex)
37              {
38                  Utility.Error.LogSql( " 生成文件出错 " , ex.ToString());
39                   return   false ;
40              }
41          }

在启动页面Page_Load
