32 string temp = HttpContext.Current.Server.MapPath("/menutest/news/text.html");
33 StreamReader sr=null;
34 StreamWriter sw=null;
35 string str="";
36 try
37 {
38 sr = new StreamReader(temp,code);
39 str = sr.ReadToEnd(); // 读取文件
40 }
41 catch(Exception exp)
42 {
43 HttpContext.Current.Response.Write(exp.Message);
44 HttpContext.Current.Response.End();
45 sr.Close();

49 //string htmlfilename=DateTime.Now.ToString("yyyyMMddHHmmss")+".html";
50 string htmlfilename="kyo.html";
51 // 替换内容
52 // 这时,模板文件已经读入到名称为str的变量中了
53 str = str.Replace("ShowArticle",strText); //模板页中的ShowArticle
54 str = str.Replace("biaoti",strText);
55 str = str.Replace("content",strContent);
56 str = str.Replace("author",strAuthor);
57 // 写文件
58 try
59 {
60 sw = new StreamWriter(path + htmlfilename , false, code);
61 sw.Write(str);
62 sw.Flush();
63 }
64 catch(Exception ex)
65 {
66 HttpContext.Current.Response.Write(ex.Message);
67 HttpContext.Current.Response.End();
68 }
69 finally
70 {
71 sw.Close();
72 }
73 return true;
74 }
75 }
76 }
77 //原理是利用System.IO中的类读写模板文件,然后用Replace替换掉模板中的标签,写入静态html.
